Paper Abstract:
|
Nowadays it is possible to deploy sensors densely into a sensing field in various sensor applications. In the densely deployed sensor networks, they select particular nodes and configure network topology with them to construct a long-lived network. Since sensor nodes have limited battery power, it is desirable to select a minimum set of working sensor nodes which should be involved in sensing and forwarding data to the sink. Previous approaches have been tried to reduce the number of active nodes to construct an energy efficient network topology but sometimes they bears a multitude of active node in a small area and makes energy consumption enlarge. In this paper, we propose a topology scheme which selects a minimum set of working nodes in the sensor network field to avoid wasting excessive energy by turning off too many redundant nodes. Our scheme offers a solution for configuring network topology with a minimal number of working nodes. Simulations show that our scheme extends the lifetime of the dense sensor networks. |
