AN OPTIMAL ROUTING PROTOCOL FOR ENERGY EFFICIENT CLUSTERING IN WIRELESS SENSOR NETWORK

Electronics and Communication Engineering

Wireless sensors nodes are made up of small electronic devices which are capable of sensing, computing and transmitting data from harsh physical environments like a surveillance field. These sensor nodes are sensitive to energy consumption and gets exhausted on working. So we need to emphasize on reducing energy dissipation of sensor nodes in order to improve network lifetime. These sensor nodes majorly depend on batteries for energy, which get deplete data faster rate because of the computation and communication operations they have to perform Communication protocols can be designed to make efficient utilization of energy resources of a sensor. Various routing protocols are developed to enhance network scalability and stability. The cluster based routing is an efficient way of reducing energy dissipation by limiting data transmission from nodes to base station. A new routing method was proposed for this purpose which improves the life span of network, its data transmitting capability with low energy consumption. A set of previously reported routing and MAC(Medium Access Control) layer protocols has abilities to achieve energy efficiency and supports real-time functionality. Multi hop routing is proposed for the transmission of data. Reduction of energy consumption is achieved with the help of TDMA scheduling. Time division multiple access (TDMA)-based MAC can potentially reduce the delay and provide real-time guarantees as well as save power by eliminating collisions. A detailed study of these protocols have been carried out and perform new approach on Network Simulator Tool the proposed protocol performance on some factors like energy awareness, network life time and packet delivery ratio and some other factors. Conclusions have been drawn the different type of graph generated by NS2 and show the comparison between op-leach and our proposed method in different parameters of how the protocol performs.
