Maximizing Network Topology Lifetime Using Mobile Node Rotation

摘要: One of the key challenges facing wireless sensor networks (WSNs) is extending network lifetime due to nodes having limited power supplies. Extending WSN complicated because often experience differential consumption. For example, closer sink in a given routing topology transmit more data and thus consume rapidly than farther from sink. Inspired by huddling behavior emperor penguins where take turns on cold extremities penguin “huddle”, we propose mobile node rotation, new method for using low-cost address consumption extend lifetime. Specifically, rotate through high locations. We efficient algorithms single multiple rounds rotations. Our extensive simulations show that rotation can eight times average which significantly better existing alternatives.
