Analysis and implementation of optimized energy-based CH selection for WSN using sun SPOT

The main constraint that affects the practical design of Wireless Sensor Networks (WSNs) is the network energy as network nodes has limited resources capabilities. Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol is one of the popular clustering based algorithms that optimize energy consumption of WSN. The selection of Cluster Heads (CHs) in each round is determined depending on a random number generated by each node, which compared to a threshold value. The generated random number is the main factor in CH selection process. Normally, the random number is varied each time when calling the random number generator. The effect of the generated random numbers is neutralized during this work to get real effect of the suggested enhancements.
