Enhancement of Transmission Range Assignment for Clustered Wireless Sensor Networks

摘要

Transmitter range assignment in clustered wireless networks is the bottleneck of the balance betweenenergy conservation and the connectivity to deliver data to the sink or gateway node. The aim of thisresearch is to optimize the energy consumption through reducing the transmission ranges of the nodes,while maintaining high probability to have end-to-end connectivity to the network’s data sink. We modifiedthe approach given in [1] to achieve more than 25% power saving through reducing cluster head (CH)transmission range of the backbone nodes in a multihop wireless sensor network with ensuring at least95% end-to-end connectivity probability.
