摘要: In a data collection sensor network, how to maximize the network lifetime through topology control remains an open research problem. Previous work has studied this problem by aiming build max-lifetime tree, however, tree-based does not necessarily yield maximum lifetime. paper, we consider collaborative multipath delivery and formulate maximization as max-fair-flow problem, then study collaboratively adjust transmission power of nodes achieve maxfair-flow, thus maximizing We give both theoretical proofs simulations validate its correctness performance.
