Ramakrishnan · Journal of Computer Science · 2009
Problem statement: Extending lifetime of the battery operated wireless sensor nodes through the design of low power medium access control protocols dealt in this study.Approach: In this study energy efficient Optimal Power Control MAC with Overhearing Avoidance (OPC-OA) was proposed.The transmission power of every node was dynamically changed for the optimal connectivity between nodes.The optimal transmission power for a link was estimated in this OPC-AC algorithm by measuring the link quality by using RSSI.The energy consumption analysis of proposed MAC had been done in MATLAB based discrete event simulation.Results: The comparison of energy consumption analysis of the proposed MAC with the On Demand Transmission Power Control (ODTPC) had been done.Conclusion: The results showed the proposed transmission power control MAC with overhearing avoidance outperforms the On Demand Transmission Power Control (ODTPC) in terms of energy consumption.
