Abstract:

To solve the problem of unevenness in energy consumption which tends to cause the network disconnection in stripbased wireless sensor networks, a improved topology control algorithm and sleep-awake scheme is proposed. Based on the set clustering, the clusterhead nodes are periodically elected under a migrationbased scheduling mechanism designed to regulate nodes duty cycles as well as intra/intercluster communication distances. And the load balance of them is achieved by adaptively adjusting the listening schedule. Simulations show that this algorithm could effectively prolong the network lifespan and improve the network completeness of the sensing area in the later period. 

Key words: strip-based wireless sensor network, network topology, sleep-awake scheme, load balance
