Abstract
The longevity of wireless sensor networks (WSNs) is a major issue that impacts the application of networks. When communication protocols are striving to save energy by acting on can be prolonged by further involving sink mobility. The most proposals give their evidence of lifetime improvement through either (small-scale) field tests or numerical simulations on rather cases, theoretical understanding of the reason for this improvement and the tractability of the joint optimization problem is still missing. In our project, we are attempting to build a framework for investigating the joint sink mobility and routing problem by constraining the sink to a finite number of locations. We also investigate the induced subproblems. In particular, we are using an efficient primal-dual algorithm to solve the sub-problem involving a single sink, and then we generalize this algorithm to approximate the original problem involving more sinks. Last we apply the algorithm to a set of typical topological graphs; the results demonstrate the benefit of involving sink mobility.
