Energy Efficient Cell Survival and Cell Merging Approaches for Auto-Configurable Wireless Sensor Networks

摘要

In practice, sensor nodes (SN) are battery-powered devices and the variant rate of depletion of power in the devices can hamper the network's efficient operation as the node lifetimes directly affect the network lifetime of wireless sensor network (WSN). There are normally, in practical systems, certain considerations taken at each layer to prolong the network lifetime. This paper focuses on the topology control process. The authors propose a new auto-configurable algorithm to re-organize the network topology efficiently. The proposed algorithm merges both cell merging and cell manager selection process together and is applied in clustered homogeneous cellular architecture. The simulation result proves that the proposed algorithm consumes less power and consequently prolongs the network lifetime than the existing auto-configurable algorithm.
