Sensor networks need to be planned but unfortunately most reported implementations are ad hoc in nature and hence lack the required robust performance. A great deal of current research on wireless sensor networks is dominated by reliance on models and experiments based on random distribution of sensors in the network and within the environments without a systematic network planning. In practice, sensor networks that will be used for day to day applications will need to be planned for coverage, performance and throughput. Understandably, the lack of planning methods for sensor networks is a limiting factor against practical implementations. Understanding how to plan sensor networks will lead to significant implementations and applications. The major objectives for planning sensor networks include enhancement of connectivity, better area of coverage, reduced interference, optimum monitoring or sensing of conditions within the geographical region of interest, topology control and network management. Unplanned sensor networks therefore effectively work against the desired objectives. Optimal placement of sensors reduces the costs of network ownership and management and enhances the detection potential of the network. A reusable sensor network planning method provides a template for rapid deployment of sensor networks in different environments and for different applications.
