Abstract: One of the most important metrics in wide area wireless sensor networking (WAWSN) is to maximize the network lifetime. In this paper, a relay selection scheme is proposed under the topology constraints to maximize the lifetime of WAWSNs through solving an optimization problem where relay selection of each node acts as optimization variable. Considering the diversity of the sensor nodes in WAWSNs, the optimization problem takes not only energy consumption rate but also energy difference among sensor nodes into account to improve the network lifetime performance. Since it is Non-deterministic Polynomial-hard (NP-hard) and intractable, a heuristic solution is then designed to rapidly address the optimization. The simulation results assumed indicates that the proposed relay selection scheme has better performance in network lifetime compared with existing algorithms and that the heuristic solution has low time complexity with only a negligible performance degradation gap from optimal value. Furthermore, we also assumed simulations based on a general WAWSN model to comprehensively illustrate the advantages of the proposed algorithm.
