The WSN network contains the combination of Infra Structure Network and Ad hoc Networks. WSN network have high reliability as the network failure will be easily managed as the network will be well equipped. In this work, we mainly focus on minimizing end to end latency, energy efficiency and congestion control as primary design objectives of routing. It is implemented by three hops routing protocol which considers three hopes to reach the destination. It uses at most two hop in the ad hoc transmission mode and one hop in the cellular transmission node. By implementing three hop routing the reliability of network will be more as the data failure will be highly addresses. So the node selection will be from both the network. In order to select the nodes we are considering the threshold value of each node. The threshold value is the unique code assigned to each node. The clustering of nodes will be based on the threshold value assigned to it. The threshold value is to maintain security in the network so that no unauthorized spoofing nodes may enter the network. This threshold distribution and data transmission will be performed using TAS protocol. This work also implements overhearing technique in which the sending node shares it content with one or more other nodes before transmission so that the failure of node may be addressed. The main objective of our work is to transfer to the information in a WSN network in a safe and secure manner. INTRODUCTION A WSN network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location. Provide a bridge between the real physical and virtual worlds. Allow the ability to observe the previously unobservable at a fine resolution over large spatio-temporal scales. It has a wide range of potential applications to industry, science, transportation, civil infrastructure, and security. The more modern networks are bi-directional, also enabling control of sensor activity. The development of Hydrid Networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, and so on.

Communication network plays an important role in providing safe vehicular movement. The main achievement of VANET is providing comfort and safety for passengers. In addition to that, various transactions like information on accident, road condition, petrol bank details, menu in the restaurant, and discount sales can be provided to the drivers and passengers. The speed and time in which the message is sent and received plays an essential part in the Intelligent Transport System (ITS). For this the VANET requires efficient and reliable methods for data communication. Most of the earlier research works deal with the transaction based services provided by road side unit. Moreover the earlier works concentrate on the Intelligent Transport System limited to the city areas where road side units are available in plenty. But this
paper discusses the usefulness of VANET outside the city limit. Usually vehicles which move outside the city area do not get the response from the Road Side Unit (RSU) as its availability is limited. For efficient data communication, an attempt has been made to create a new clustering concept among the VANET nodes. The approach of the present paper considers the Simple Highway Vehicular model (SHWM), in which a new
clustering model has been introduced. This paper also focuses the service discovery through VANET in the absence of road side units when the vehicles are moving inside the city or outside the city.

Wireless sensor network WSNs consists of densely deployed sensor nodes, which have limited computational capabilities, power supply and computational bandwidth. These small, smart and inexpensive sensing and computing devices open new vista for scientists and engineers to observe and monitor physical phenomenon. Many works have been done through routing protocols that allow the sensor to distribute the data efficiently with limited energy supply. In this thesis, we propose a ovel routing algorithm to disseminate information via multiple path in static and energy constrained WSNs. The algorithm consists of distributed multipath search protocol and a load balancing algorithm. The multipath search protocol discovers multiple node disjoint path that connect a pair of sink and source node. The load balancing algorithm helps the sink node to allocate traffic over multiple paths found based on their cost which depends on the energy level and the hop distances of nodes along each path. We consider it as a key to improve the energy Efficiency in our protocol. The result is based on the use of ns2 simulator show that our algorithm can prolong the network life time by 9% to 18% and reduce the node energy consumption by a maximum of 34% over comparable schemes, including the energy aware routing, the directed diffusion, and the direct transmission. And these mechanism result in a significant improvement of Throughput, energy consumption and packet delivery ratio.

Nowadays, wireless sensor networks (WSNs) seen as an emerging technology due to its multi serviceable, low cost and low power sensor nodes that are deployed randomly and densely over a network to collect useful information from there. Since the nodes are deployed densely, makes it hard to recharge or replace their batteries. In this paper introduce the new protocol Energy Efficient Low Cost Clustering (EELCC) four-layer framework is proposed for mobile data collection in wireless sensor networks, which includes the sensor layer, cluster head layer, least cost routing layer, mobile collector layer, here cluster heads send a short range advertisement broadcast message. The sensor nodes receive the advertisements and choose their cluster heads based on the signal strength of the advertisement messages. Each sensor node sends an acknowledgment message to its cluster head. Moreover, in each iteration, the cluster heads choose a set of associate heads based on the signal strength of the acknowledgments. A head-set consists of a cluster head and the associates. The head-set member is responsible to send messages to the base station. Each data transfer phase consists of several epochs. Each member of head-set becomes a cluster head once during an epoch. A round consists of several iterations Results show that this protocol reduces energy consumption quite significantly and prolongs the life time of sensor network as compared to Low-Energy Adaptive Clustering Hierarchy (LEACH).

ABSTRACT On transferring voice over a packet switched network, packet loss is unavoidable. Hence it is necessary to recover lost voice packets. Many recovery techniques were developed to recover in real-time as voice is a real-time traffic. These recovery techniques repair only during loss periods neglecting the effect of loss on the subsequent speech segments. This paper has developed an enhanced technique called Parallel Recovery Technique (PRT) to alleviate this shortcoming in other recovery techniques. PRT is found to perform better than other methods with a close to zero added complexity. The results show improvement in perceived voice quality of about 10% at 20% loss rate.

Modern companies, including telecommunication ones and mobile operators, working in the global environment, need to guarantee technological effectiveness and innovation, renewing their technologies and services. Communication technologies and variety of services are to be improved and developed extremely fast. This results in the need for constant adaptation and reconfiguration of complex software systems, used in global environment to provide and monitor deployed services. For instance, OSS/BSS is used in the domain of telecommunication companies. Reconfiguration of complex software systems covers application development for service provisioning, their dynamic monitoring and reconfiguration. Currently, system adaptation and service design strategies are poorly formalized and validated. In current state-of-the-art approaches, several iterations involving analysts and system architects are necessary, resulting in time and money consuming service development. The approach proposed in ...

In this paper Autonomous Mobile Mesh Network with security. In Mobile Adhoc Network nodes move from one place to another place in free directions. The movement of the nodes may split the network and form more than one group. In this case communication between two nodes will be disconnected. To maintain the communication between all nodes even they are in different groups Mesh Nodes are used. Mesh Nodes which have the capability of changing its nature into Inter-group router or Intra-group router. Even it can act as a bridge router. To make the communication effective One-hop neighbor information update is used to find the shortest path between any two nodes. Since nodes move from one place to another place intruder may join the group. To avoid this problem private key is assigned for all the nodes in the network and it is shared among the nodes. If any node want to communicate with the other node first private key must be exchanged. Only if private key matches nodes can communicate. If key does not matches then the node ID will be registered in the Blacklist. If any node registered in the blacklist says the private key wrongly, then the node will be removed from the network. In this way security can be provided to the network. Now a Days MANETs, however, may suffer from network partitioning. This limitation makes MANETs unsuitable for applications such as crisis management and battlefield communications, in which team members might need to work in groups scattered in the application terrain. A new cryptographic algorithm is developed to improve the time for encryption and decryption of data of end-to-end delay and provide higher level of security.

Abstract Location-based routing has received significant attention for ad hoc networking. The motivation to use location-based routing is that it eliminates the need to maintain routes and therefore is very well suited for highly mobile networks. However, as an essential prerequisite for location-based routing, a location service is needed from which a node can learn the current position of other nodes present in the network. We present a zone-based location service (ZLS), which provides a mechanism to track the location information of ...

In this work, we propose a Comprehensive Learning Particle Swarm Optimization (CLPSO) based weighted clustering algorithm for mobile ad hoc networks. It finds the optimal number of clusters to efficiently manage the resources of the network. The proposed CLPSO based clustering algorithm takes into consideration the ideal degree, transmission power, mobility, and battery power of the mobile nodes. A weight is assigned to each of these parameters of the network. Each particle contains information about the cluster-heads and the members of each cluster. The simulation results are compared with two other well-known clustering algorithms. Results show that the proposed technique works better than the other techniques especially in dense networks.
