Abstract: Data aggregation problem with maximising network lifetime is one of important issues in wireless sensor networks. In this paper, we study the maximum lifetime many-to-one data gathering with aggregation (MLMTODA) problem: given locations of sensors and a base station together with available energy of each sensor, and a set of sources, find a schedule in which data should be gathered from all the sources and transmitted to the base station, such that the lifetime of the network is maximised. We propose efficient algorithms to solve the MLMTODA problem. Our simulations demonstrate that the proposed algorithm has a good performance for the MLMTODA problem.

Keywords: data aggregation; many-to-one; maximum lifetime; wireless sensor networks; WSNs; wireless networks; network lifetime; scheduling; simulation.
