Mobile Ad hoc Networks (MANETs) are wireless infrastructure less networks can be easily formed or deployed due to its simple infrastructure. Since each node acts as a router, the nodes must assist in discovery and maintain the network routes for long standing which is not possible due to limited battery source. This reflects on link failures which increase the overhead. Since the MANETs has tremendous applications in commercial, military, mobile conferencing outside the office, battlefield communications, embedded sensor devices that automate household functions, etc. , the goal is to maintain the network sustain for long by reducing power consumption. The power consumption plays a vital role in MANETS, and there are lots of low power consumption techniques were designed. Among many, data compression technique is a simple technique, with the benefit of reducing the transmission rate that consumes less bandwidth and low power. Hence in this work, Lempel – Ziv – Welch (LZW) compression algorithm is implemented and the simulation results proved that the data can be transmit with low power consumption without any loss of data. This, in turn helps in reducing the battery consumption, thereby increasing the battery life.
