An ad hoc network is a mobile wireless network that has no fixed access point or centralized infrastructure. Each node in the network functions as a mobile router of data packets for other nodes and should maintain the network routes for long standing which is not possible due to limited battery source. Also, due to node mobility, link failures in such networks are very frequent and render certain standard protocols inefficient resulting in wastage of power and loss in throughput. The power consumption is an important issue with the goal to maintain the network lives for long by consuming less power. The power consumption can be achieved by modifying algorithms such as cryptographic algorithms,Routing algorithms, Multicast Algorithms, Energy Efficient Algorithms and Power Consumption Techniques in High Performance Computing, Compression and decompression algorithms, minimizing link failure algorithms, and by power control algorithms. In this work, we have proposed a new algorithm for minimization of power consumption in Ad hoc networks. The performance of the proposed model is analyzed and it is observed that, information could be sent with security consuminglesscomputational power, thereby increasing the battery life.

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.
