Wireless Sensor Networks (WSNs) have gained a lot of attention in both public and research communities. One issue in wireless sensor networks is achieving efficient operation because of the limited available power. Many Heuristics were designed to enhance power reservoir of sensors and maximize their life time. Online Maximum Lifetime heuristics (OML) and Capacity Maximization (CMAX) are a well-known routing heuristic for maximizing lifetime of WSN. The connectivity and placement of sensors were simulated based on Uniform distribution. Uniform distribution simulates a terrain free environment. Recent study shows the effect of different distribution (Poisson distribution) to simulate the terrain changes of earth surface and the effect on both the lifetime of WSN and the stability of protocols under study.
