Optimum of Routing in Wireless Sensor Networks Based on Hierarchical Protocols

Wireless sensor network consists of many sensor nodes that they are distributed in the environment and are connected via a wireless link. The main task of nodes is collecting data from their surroundings and send it to the control center itself. The advantage of wireless sensor networks is : Easy to set up, being in certain places inaccessible, no need for special infrastructure and stability in the face of the failure of nodes. In wireless sensor networks, there are also limitations. The most important limitation of nodes is energy supply The main purpose of this paper is to study Routing protocols in wireless sensor networks and the optimization in a hierarchical protocol to reduce energy consumption and increase the lifetime of wireless sensor network.
