An analytical model for Energy Consumption in Y-MAC Protocol

This paper presents an analytical model for estimating energy consumption in Y-MAC protocol for Wireless Sensor Networks (WSN). This protocol has been proposed to reduce the energy consumption of a node when involved in unicast or broadcast transmission of frames. In WSN a node consumes energy in transmitting and receiving of data, listening transmissions of other nodes, and in sleep mode. Therefore, energy consumption of a node has been estimated by adding up the energy consumed in each of the above activities. This has been achieved by estimating the time spent in each activity by a node. The protocol has been simulated using MATLAB. The simulation results show comparable energy savings as compared to Y-MAC protocol, therefore, the model validates the existing protocol.
