Wireless sensor networks are infrastructure-less and fully distributed systems of self-configurable and self-organized nodes that are wishing to share data over the air. Nodes could be PCs, mobile phones, printers, etc. The main challenge of sensor networks is its characteristics (dynamic topology, variable capacity, infrastructure less, bandwidth, computing power, battery lifetime, etc.). Another challenge is the deployment operation. In this paper, the authors proposed a method of random deployment (algorithm) and simulation tool to simulate how these sensors work and find the solutions to increase their lifetime, and find the suitable method for deploying sensors in the targeted area (such as isolated area, military area and in areas infested with terrorist) by using some algorithms that reduce the sensor energy.
