摘要
水声传感器网络的物理特性使其路由协议必须以节省能量为重要目标。在地理能量感知路由(GEAR)机制的基础上,提出了一种基于功率控制的地理能量感知路由(PC-GEAR)机制。该机制通过调整节点发送功率来达到提高能量效率的目的。仿真结果表明:PC-GEAR机制的效果是明显的。
Physical characteristics of underwater acoustic sensor networks make energy-saving become an important goal for designing routing protocol. On the basis of geographical and energy aware routing（GEAG） mechanism, a power control based geographical and energy aware routing （PC-GEAR） strategy is proposed. This mechanism transmit power by adjusting nodes to achieve the goal of increasing energy efficiency. Simulation results show that the effect of PC-GEAR is obvious.
