Wireless Sensor Networks (WSNs) have important applications in remote environmental monitoring and target tracking. The development of WSNs in recent years has been facilitated by the availability of sensors that are smaller, less expensive, and more intelligent. Each sensor node is battery powered and it is not convenient to recharge or replace the batteries in most of the cases, especially in remote and hostile environments. The design of a WSN depends significantly on its desired applications and must take into account factors such as the environment, the design objectives of the application, the associated costs, the necessary hardware, and any applicable system constraints.
