A Novel Approach to Optimize Energy in WSN using BellmanFord Asynchronous - SW Protocol

Energy optimization is a prime issue in wireless sensor network that consumes less energy to give optimum performance under low battery power, limited bandwidth and network life time of each node. In this paper, first we investigate and analyze three network layer protocols, centralized, localized, bellman ford(distributive) and next we develop a new algorithm called bellman ford asynchronous sleep wake up protocol for energy saving in packet transmission and to prolong the network lifetime. The simulation results on metrics energy spent, throughput, average delay and product delivery ratio confirms that the new protocol outperforms the other protocols.
