Energy efficiency in MANET

Subject Area: Engineering

This paper presents the improvement ofenergy efficiency on a mobile ad-hoc network(MANET) using an energy optimization algorithm (EOA). The study addresses the issues of high energy consumption in MANET application. This was achieved by developing an EOA which considered the dynamic behaviour of nodes and adjusts the energy level, to minimize unnecessary energy consumption, especially during inactive periods. The algorithm was integrated in MANET nodes and simulated over 100 minutes of communication. The results in every 10 min of communication is 73.35%, with 4.06J of energy consumed per second. The results obtained were validated using ten-fold cross validation approach over 100minutes of nodes communication process and theyreported an average energy level of 73.96%, then 4.5J/s for the average energy consumed. Overall the result showed that the energy level of the nodes over 100minutes of communication remained 73.96%, which is very good, and will improve the application time of the nodes. More so, a comparative analysis of the EOA with a rule-based energy conservation algorithm in MANET, reported a reduction of 49% in energy level with EOA, and also 22.62% decreased in energy consumed per seconds with EOA.
