Coverage-Preserving Multi-Path Routing Algorithm for Wireless Sensor Networks
A major challenge in sensor network is to preserve the coverage of the sensing network for the maximum possible time. When the density is sparse, coverage needs to be preserved by using energy-efficient route-selection algorithms. Coverage-preserving multi-path routing algorithm has been proposed that conserve energy while increasing the lifetime of routes and keep preserving network coverage.
