| 摘 要： | 为了降低无线Ad hoc网络中节点的能量消耗，该文提出了一种基于节点位置的功率控制算法(PCAP)。PCAP算法通过分析节点间的位置关系，建立节点的优化邻居集合，并对路由层报文、MAC层控制报文和其它数据类报文使用不同的功率控制策略。PCAP算法在保证网络连接性的同时能降低网络能量消耗，计算机仿真表明，PCAP算法在MAC层的吞吐量、MAC层丢包、端到端时延等方面取得较好的性能表现。

| Abstract: | In order to reduce energy consumption of nodes in the wireless ad hoc networks, a Power Control Algorithm based on Position of node (PCAP) is proposed. By analyzing the relationship between nodes, the Optimized Neighbor Set (ONS) of node is built. PCAP uses different power control policies for routing packets, control packets of MAC layer and other data packets. PCAP algorithm can reduce the energy consumption and guarantee the connectivity of network. The simulation results indicate that it can achieve well network performance, such as the throughput of MAC layer, dropped packets and end to end delay. |
