Abstract

In wireless sensor networks (WSNs)

energy hole problem is a key factor for affecting the lifetime of networks.In a circular multi-hop sensor network (modeled as concentric coronas)

the optimal transmission ranges of all coronas can effectively improve system lifetime.For the WSN with non-uniform data generating rate

an energy-efficient algorithm for non-uniform data generating rate (EANR) can search approximate optimal transmission ranges of all coronas in order to prolong network lifetime by constructing coronas relationship table.EANR can reduce the searching complexity and get results approximated to the optimal solution.The simulation results indicate that the lifetime got from EANR approximates to the lifetime from the optimal list.Compared with the algorithms in other literatures

EANR can prolong the network lifetime.
