ENERGY OPTIMIZATION IN WSN USING CHANNEL CODING
Journal Title: World Journal of Engineering Research and Technology - Year 2018, Vol 4, Issue 1
Abstract
The Wireless Sensor networks are highly distributed networks of small, lightweight wireless nodes, deployed in large numbers to monitor the physical or environmental conditions. The major challenges of WSN arerobust, reliability and power consumption Source of Power supply used in sensor nodes are often battery powered. Hence a frequent requirement for charging of battery or sometimes replacement of sensor nodes itself is necessary. For maximizing the lifetime of sensor node, Optimization[5] of power consumption plays an important role. Error correction codes (ECC) is an efficient method implemented to optimize the transmitted power. In this paper a systematic approach for selection of suitable error correction codes for wireless sensor networks is followed. Coding gain of ECC results in energy conservation during transmission. Suitable Error correction code will be chosen based on the trade off in performance between BER (Bit Error Rate) and power consumption.
