Collaborative Topology Control for Lifetime Maximization


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 to build a max-lifetime data collection tree, however, tree-based data collection does not necessarily yield maximum network lifetime. In this paper, we consider collaborative multipath data delivery and formulate the lifetime maximization problem as a max-fair-flow problem, then study how to collaboratively adjust the transmission power of sensor nodes to achieve the maxfair-flow, thus maximizing the network lifetime. We give both theoretical proofs and simulations to validate its correctness and performance.
