This research paper explain about the wireless distributed micro sensor systems are enabling the reliable monitoring of a variety of environments for both civil and military applications. In this work, we look at routing protocols, which can have significant impact on the overall energy dissipation of these networks. Based on our findings that the conventional routing protocols of direct transmission, minimum-transmission-energy, multi hop routing, and static clustering may not be optimal for sensor networks, we propose KNN based routing protocol , a inter clustering-based protocol that utilizes randomized rotation of local cluster base stations (cluster-heads) to evenly distribute the energy load among the sensors in the network. It uses a non-localized coordination to enable scalability and robustness for dynamic networks, and incorporates data fusion into the routing protocol to reduce the amount of information that must be transmitted to the base station. Simulations show that it can achieve as much higher factor of reduction in energy dissipation compared with conventional routing protocols. In addition, it is able to distribute energy dissipation evenly throughout the sensors, doubling the useful system lifetime for the networks we simulated.
