Wireless sensor network is a highly distributed network with small wireless nodes that are deployed in large numbers to monitor the environment by measurements of physical parameters. Wireless sensor networks have limited bandwidth, processing power and energy. Each node in the wireless sensor network may provide multiple services that when communicated to the base station will consume more energy as the distance between them increases. Such a dynamic environment requires a continuous adaptation of the composition of services. Service composition can be categorized as static and dynamic compositions.
