ABSTRACT

Wireless sensor networks, trend of the past few years involves in deploying a large number of small nodes. The nodes then sense environmental changes and report them to other nodes over flexible network architecture. A prototype was developed with a mesh topology of wireless sensor network for analysis of various message costs as well as the overall cost of data messages. Here a new task of task dissemination scheme is used, that can disseminate tasks into a subset of the sensor network. In which it uses a tree which is formed when the source node broadcasts the code version messages. The source node keeps the tasks and sends it based on the requests. This scheme also supports newly emerging wireless sensor network architectures with layered structure and mobile sensor nodes.
