Multiple Event Source Routing (MESR) for Energy Efficient Wireless Sensor Network
The Wireless Sensor Network (WSN) is used to sense different events occurring at different sections of the remote network. The sensor nodes have limited battery power, and the nature of their deployment makes recharging almost impossible. To limit the power drain, efficient communication protocols are needed. This paper proposes Multiple Event Source Routing (MESR) for sending critical information by optimal path, so that it reaches the base station in shortest possible time. MESR sends regular or not-so-critical information in one of the multiple routing paths. MESR is capable of handling multiple events simultaneously. It defines an overhearing ratio in order to reduce an overhearing energy waste among selected paths. Thus MESR protocol improves reliability as well as network lifetime also.
