A Traffic Adaptive Routing Protocol for Mobile Sensor Networks
Ki-Sup Hong, Sanghoon Lee, Lynn Choi · 2011
In this paper we propose a traffic adaptive routing protocol called TAR for mobile sensor networks (MSNs) where any node can move any time. Although MANET routing protocols can be used for MSN they generate too much unnecessary traffic for low mobility environment and also by assuming peer-to-peer communication patterns. TAR can mitigate such overheads by analyzing and predicting the source, volume, and the patterns of the traffic as well as those of the mobility. TAR also provides fast route recovery to dynamic topology changes. We have implemented TAR in the NS-2 simulator. Our experimental evaluation confirms that TAR can improve both the network and energy performance by up to 53 percent for MSNs compared to the MANET routing protocols.
