PJ6400: Mobile Collector in Defense against Jamming Attack

A jamming attack on a wireless network is an attack in which the adversary attempts to cause a denialof-service (DoS) by conducting simple, continuous or intermittent, transmission of high-power interfering signal. Wireless sensor networks (WSNs) are particular vulnerable to jamming attacks due to its natural characters. In our work, we propose to combat jamming attacks on WSNs through the deployment of mobile nodes. Specifically, we consider sending a mobile node inside the jammed area to periodically collect/sense data. Subsequently, the mobile is responsible for bringing the data to the most optimal exit point/node on the boundary of the attacked region. An algorithm named COEP is proposed for calculating the optimal exit point according to varies network conditions.
