Description

Method for Providing a Direct Communication Between 6LoWPAN Communicator and 6LoWPAN Sensor Node
Field of the Invention
The present invention relates generally to a method for providing a direct communication between a 6LoWPAN Communicator and a 6LoWPAN sensor node, and more particularly to a method for requesting data by the 6LoWPAN communicator from a sensor node, and sending data from the sensor node to the 6LoWPAN communicator without using routing mechanism.
Background of the Invention Generally, data packets in a conventional network traverse to the outside network through a router or gateway. The routing of the packets depends on the routing protocol used in a specific network.
Low power wireless sensor devices are used in low power wireless private area network (LoWPAN) and standard IEE 802.15.4- based network. The use of
Internet Protocol Version 6 (IPv6) makes the communication more visible across various networks and devices. 6LoWPAN, one of the Internet Engineering Task
Force (IETF) standard is adopted for the sensor devices so that it becomes an open standard in the market (compares to other dominated proprietary standards available in the market).
The present invention provides a method for sending IPv6 packets directly to 6LoWPAN communicator without going through a router or gateway. The transmission of the packets to the communicator occurs only when the packets are requested by the communicator.

The present invention provides a method for providing a direct communication between a 6LoWPAN communicator and 6LoWPAN sensor nodes. The method includes data requesting and forwarding algorithms in a
6LoWPAN which send packets from a sensor node to the 6LoWPAN communicator in a single hop without using routing mechanism. The algorithm needs to be loaded into both communicator and sensor nodes to allow the communicator to request for packets and to allow the sensor nodes to send packets.
According to the present invention, the method for requesting information from a sensor node by a communicator, and sending data from the sensor node to the communicator in a network such as 6LoWPAN , the method comprising
a) locating sensor nodes within the network range by using a node detection mechanism in the communicator
b) requesting data from a particular sensor node by sending specified header and data;
c) verifying and processing the data wherein the processes are perform in the sensor node;
d) transmitting the processed data from the sensor node directly to the communicator in a single hop without using a router or gateway by sending specified header and data;
e) verifying the transmitted data for validity by checking whether it is originated from a valid sensor node;
f) processing the transmitted data for obtaining its IPv6 address wherein the address will be translated and displayed on the communicator. According to the present invention, the method includes the use of is 6LoWPAN- communicator and 6LoWPAN sensor node. The 6LoWPAN communicator detects the present of sensor node in a 6LoWPAN network. The 6LoWPAN communicator which acts as a requestor will generate a request message to a particular sensor node for acquiring its information. The information transmitted from the sensor node to the communicator will be translated and generated into an appropriate IPv6 address and preferably displayed on the communicator. During this communication, the 6LoWPAN sensor node verifies the validity of the requestor. The sensor node will process the valid data and send the processed data back directly to the communicator.
Detailed Description of the Invention
Using sensors in low power wireless private area network gives an added advantage to the network compared to a conventional method whereby it breaks the barrier of end-to-end communication. Data from the sensors can be either sent to a web server, as in conventional method, or sent directly to the requestor.. A direct communication is possible because the network protocol used in this network is the same. The transmission of packets in both communication method uses sensor router of the gateway.
According to the present invention, a 6LoWPAN communicator is configured to communicate and get information directly from a sensor node without the packets i.e. transmitted data going through a router or gateway. The 6LoWPAN communicator has 802.15.4 interface for communicating with the sensor node(s). Preferably, the communicator has multiple interfaces which includes the 802.15.4 interface for 6LoWPAN network and at least another interface for accessing backhaul network. For example, the backhaul network could be WiFi, WiMAX, HSDPA or any other access. If the communicator has the access for both backhaul network and standard 802.15.4, the priority to request the data is by using the backhaul network. In the absence of the backhaul coverage, the communicator retrieve information from the sensor using 802.15.4 interface directly.
The present invention allows peer-to-peer communication between a 6LoWPAN communicator and sensor node(s). Data requesting by the communicator, data processing by the sensor node and data transmission by the sensor node to the communicator occur without an intermediate route. This does not disrupt the normal transmission to the outside network which uses an intermediate router. The communicator, for example, is a mobile device which has the capability of detecting the sensors available on a network. When a user identified and selected a particular sensor node of which he want to receive information from, a request message will be sent to the sensor node. The sensor node will verify the request message and its source in order to avoid security violation.
Then, the sensor node will then send the requested information. The data would be sent either in a single hop or in multiple hops from sensor to the communicator.
If the communicator is only reachable using multiple hops, a separate packet forwarding mechanism need to be in place. The method used in the present invention is single hop packet forwarding.
Fig. 1 is a flow diagram showing the steps involved when a 6LoWPAN communicator or requestor requesting information from sensor nodes in a 6LoWPAN network according to a preferred embodiment of the present invention. In this communication, a dedicated communicator, for example a mobile device, will request data from the sensor node. In other words, the communicator acts as a requestor. A node detection mechanism of the communicator will detect sensor nodes within the network range. Once the sensor nodes are detected, a preferable node is selected for requesting its data. The communicator packet, which is different from a router packet will be sent to selected node wherein the communicator packet comprises a header with a specified data.
In this communication, the sensor nodes are configured with specified parameter to response to requests from the dedicated communicator wherein the nodes will verify the data for further processing. If the requested data matches the parameter, the request will be processed and information will be transmitted to the communicator. Otherwise the request will be dropped by the sensor node. The transmitted information comprises a header with a specified data or character which is known only by the dedicated communicator or requestor. As shown in Fig. 2, the communicator will verify the validity of the information by checking whether the information is originated from a valid sensor node. The communicator will then check the address of the information. If the address is in the form of full IPv6, the information will be directly displayed on the communicator. If the address is short address, the communicator will translate the short address and the full IPv6 address will be generated before displaying the information on the communicator.
An overview of the communication mechanism between communicator and sensor node are shown in Figs. 3 and 4. As shown in Fig. 4, information from a sensor node is transmitted to and displayed on a mobile communicator.
