Prolonging network lifetime is one of the most important design objectives in energy-constrained wireless sensor networks (WSNs). Using a mobile instead of a static base station (BS) to reduce or alleviate the non-uniform energy consumption among sensor nodes is an efficient mechanism to prolong the network lifetime. In this paper, we deal with the problem of prolonging network lifetime in data gathering by employing a mobile BS. To achieve that, we devise a novel clustering-based heuristic...[Show more]
