Security is extremely important for the deployment of a mobile ad-hoc networks (MANET) due to its openness to attackers, the absence of an infrastructure, and the lack of centralized administration. Most research efforts have been focused on secure routing protocols, the distributed certificate authority, and key distribution, while a few projects have focused on secure autoconfiguration. However,...
Wireless Sensor Networks (WSNs) are exposed to numerous security threats that can affect the execution of applications. Securing WSNs is challenging due to their unique nature as an application and a network, and due to their limited capabilities. Therefore we introduce SM-Sens, a secure middleware that helps bridge the gap between high-level application requirements and WSN managing complexity. Our...
Previous research on sensor network security mainly considers homogeneous sensor networks, where all sensor nodes have the same capabilities. Research has shown that homogeneous ad hoc networks have poor performance and scalability. The many-to-one traffic pattern dominates in sensor networks, and hence a sensor may only communicate with a small portion of its neighbors. Key management is a fundamental...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
Mobile ad-hoc networks (MANET) have found strategic importance in real world applications like environment management, remote explorations, disaster and warfare conditions due to their dynamic, self tailoring and adaptive nature. These networks can be quickly deployed in situations where no infrastructure exists. Effective use of these networks is largely dependent on secure and reliable behavior...
