Many tasks require multiple sensing capabilities; in Wireless Sensor Networks (WSN), it is expensive to deploy a homogeneous network wherein every sensor has the same functionality. Instead, it is economical to deploy a heterogeneous network wherein sensors differ in their capabilities; in such a network, efficient data querying is essential. We propose a multi- keyword routing protocol, iBubble, for Heterogeneous

There has been a vast amount of research and development effort aimed at providing solutions and products that address the security needs in the information age. Each solution tends to address only a particular facet of the security problem and only accessible to limited protocols or applications. Moreover, ad hoc deployment of some solutions (e.g., firewalls and IPsec) can hinder our ability to collaborate across networks. A very important question is how any application can discover policy restrictions brought about by these solutions/mechanisms, and make efficient use of them to satisfy the application's security goals. The Celestial project addresses this question by developing a security management architecture that can (1) automatically discover effective security policies and mechanisms along any network path, (2) dynamically configure security mechanisms across protocol layers and across the network, (3) adaptively re-configure these mechanisms to maintain certain levels of security services when the network is under stress. This paper describes the Celestial system design and implementation, and reports the current status of the project

As wireless motes are battery powered, many listen- sleep Medium Access Control (MAC) protocols have been pro- posed to reduce energy consumption. Security issues related to the design of these protocols have, however, largely been ignored. In this paper, we present a novel attack (the synchronization attack) on listen-sleep MAC protocols. This attack can cause 100% message loss and approximately

A coordination language, MELDC, for open systems programming is presented. MELDC is a C- based, concurrent, distributed object-oriented language built on a reflective architecture. Unlike other language research, the focus of MELDC is not only to study what specific language features should be designed for solving certain open system problems but also to provide programmers a high-level and efficient way

The JiNao IDS project focuses on detecting intrusions, especially insider attacks, against the OSPF (Open Shortest Path First) routing protocol. This paper presents the design, implementation and experiments of the protocol analysis and statistic anomaly detection modules in JiNao. Three OSPF insider attacks (i.e., maxseq, maxage, and seq++ attacks) have been developed for evaluating JiNao's detecting capability. JiNao's protocol analysis
