Agent Based Multipath Routing in wireless sensor networks

Recently, mobile agents have been used to solve many problems in wireless sensor networks. They are usually transferred from a node to another to aggregate the sensed data and simplify the complexity of the routing algorithms. Intelligent agents can reduce the communication cost over a very low bandwidth links among the sensors. In this paper, we propose an agent based multipath routing (ABMR) algorithm for wireless sensor network. The algorithm considers many of the sensors and the monitored field parameters such as energy, reliability, and number of hops, as well as the data importance. The algorithm builds a reliable multiple paths from the source to the destination. The number of paths is selected based on the importance of the sensed data. Intelligent agents are designed to construct the multipath as well as to send the sensed data to its destination. To show the effectiveness of the proposed algorithm, ABMR is compared to non-agent based algorithm (NABMR) as well as to one of the recent multipath routing algorithm through an extensive set of experiments.
