Dynamic Sleeping Algorithm Based on AHP for Wireless Sensor Networks

Saving energy is one of the key problems of applying wireless sensor network. Clustering and sleeping scheme have good influence on prolonging of lifetime of network and enhancing of energy efficiency. This paper proposes a dynamic sleeping algorithm basing on analytic hierarchy process (AHP), under the condition of heterogeneous industrial sensor clustered-networks. The simulation result indicates that dynamic sleeping algorithm basing on AHP is feasible. It has notable benefit on prolonging of lifetime of network and enhancing of energy efficiency.
