Adaptation of SMAC Protocol with Adaptive Listening for Wireless Sensor Networks

Wireless sensor networks consist of sensor nodes which are expected to be battery-powered and hard to replace or recharge. Thus, reducing the energy consumption of sensor nodes is an important design consideration in wireless sensor networks. The purpose of this paper is to simulate the study of S-MAC protocol under dynamic spectrum access, lot of energy is wasted in wireless sensor networks (like in idle listening, retransmission etc.) to solve this problem we have implemented S-MAC protocol with periodic sleep and adaptive listening that reduces the energy consumption by (minimizing the wastage of energy) The proposed model is compared with S-MAC with periodic sleep, S-MAC without sleep and IEEE 802.11 Simulation results describes that the proposed model optimizes the energy consumption and increases the throughput network simulator 2 has been used to develop the entire model.
