The science of computer networking and the advancements in the mobile devices enabled the capability of communicating with each other even in the absence of preexisting communication infrastructure. These networks require specialized routing protocols due to their ad hoc nature. Currently, the wireless sensor network is facing four major issues namely power management, localization, routing and deployment techniques. Out of these in power management, energy conservation and coverage efficiency are the main issues. Energy is the main constraint of wireless sensor networks (WSNs) due to irreplaceable and limited power sources of the sensor nodes. We will study the AODV routing protocol and use some algorithms to improve the AODV routing and to make the AODV routing protocol more efficient and reliable. AODV is the ad-hoc on demand routing protocol in which the routes are created and terminated as per requirement of the data transfer in the network. Hence the shortest path is required for data transfer. If the same path is followed again and again, nodes will be out of battery and whole network will be affected. So we need to decrease the power consumption by the nodes by decreasing the load on the nodes and hence thereby increasing the lifetime of the nodes. In wireless monitoring systems, these quality of service factors are very crucial and are required to make the system reliable. In this paper we have proposed an efficient optimized routing technique using flower pollination algorithm.
