A density-based self-configuration scheme in wireless sensor networks

A sensor network application that should be deployed densely selects particular nodes and configures network topology with them to construct a long-lived network. Only the active nodes participate in message transmission through a routing path and the other nodes turn off their radios to save energy. Previous approaches have been tried to reduce the number of active nodes to construct an energy efficient network topology. However, they preclude the existence multiple active nodes within a small area. The crowded active nodes can reduce network efficiency since they make frequent collisions of messages. In this paper, we propose a self-configuring sensor network topology scheme, that can achieve scalable, robust and energy efficient sensor network based on distance between active nodes. Our scheme may uniformly distribute active nodes in a sensor field and get good energy utilization.
