Levelled and sectored Meshed Multipath Routing strategy for cognitive Wireless Sensor Networks

One of the major issues of Wireless Sensor Networks is developing an energy efficient routing strategy. In this paper, we present one such protocol having Meshed Multipath Routing with Levelling and Sectoring. We first perform the levelling and sectoring of the network, where each node is assigned a Level id and Sector id with respect to the destination node. Then, we use this information in route discovery procedure and further in the actual routing process using Packet Replication method. Simulation results prove that LS-MMPR strategy gives better performance than L-MMPR and ordinary MMPR.
