| 摘 要： | 针对无线传感网（WSNs）中节点间不对称的发射功率引起的隐藏节点和暴露节点问题,提出一种用于传感网功率控制的MAC协议（MAC4PC）.该协议采用邻节点向量表对邻节点的状态及当前会话的信息进行记录,并设计了相关的控制帧收发时序和干扰度判断准则,以保证新建立会话与当前会话互不干涉,从而实现暴露节点的并行传输.仿真结果表明,与802.11 DCF协议、SB-FSMA/CA协议以及GLPCB-PMAC协议相比较,MAC4PC协议提高了网络平均吞吐量,降低了节点平均能耗和数据分组的平均传输时延.

| Abstract: | Aiming at the hidden node and exposed node problem caused by asymmetry transmit power in wireless sensor networks(WSNs),an MAC protocol for power control(MAC4PC) is proposed,which adopts a neighbor vector to record the status of neighbor nodes and the information of current conservations.Furthermore,a time schedule of the control frames and an interference degree criterion are designed to ensure the feasibility of parallel transmission in this protocol. Simulation results show that,in comparison with 802.11 DCF,SB-FSMA/ CA and GLPCB-PMAC,MAC 4 PC protocol not only improves the average network throughput,but also reduces the average energy consumption and the average delivery delay. |
