WSN: Lifetime Maximization of Rumor Routing Protocol with Optimization Scheme and Bandwidth Evaluation

Rumor routing protocol in wireless sensor networks (WSNs), is based on query system. It selects the next hop randomly, but the resultant path from source to destination is not optimal. Most of the work reported on energy efficient and bandwidth estimation in the literature are based on hierarchical protocol. However in this work we have considered data centric protocol and used optimization scheme. We have used ant colony optimization (ACO) in rumor routing protocol. This approach optimizes the route search and helps in establishing a complete route by minimizing the probability of the loop route generated by routing scheme. Energy of the nodes has been calculated and compared for normal routing process with optimizing route searching using ACO. Results are compared with non-optimized route of rumor routing protocol. Further the bandwidth of non-optimal route has been calculated and compared with optimize route.
