An ad hoc network is a group of wireless mobile computers or nodes in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. In this paper I presented the design and performance evaluation of a new on demand ad hoc routing protocol, called SWARM. SWARM used mechanisms of swarm intelligence to based select good...
For safety and privacy protection, nodes participating in ad hoc networks must keep their precise location in secret. When having to report its location (for routing purposes, etc.), a node can report only a cloaking region, a spatial region that contains its current position. Reducing location resolution has a significant impact on the applications that rely on nodes' location information. These...
In mobile ad hoc networks the nodes are dynamically changing and they have a fully decentralized topology. Hence, security is hard to achieve due to the dynamic nature of the relationships between the participating nodes as well as the vulnerabilities and limitations of the wireless transmissions medium. We proposed a novel agent based framework to monitor, detect, and isolate misbehaving nodes in...
