一种适用于Ad Hoc网络的多信道能量高效MAC协议

Adaptive Power Efficient Mechanism for Multi-channel MAC Protocol in Ad Hoc Networks

对多信道条件下MAC协议功率控制机制进行了分析,提出一种能够根据各个接收节点的通信状况,动态地调整数据信道上数据帧的传输功率和控制信道上CTS帧的发送功率的多信道Ad Hoc网络能量高效的MAC协议(MPEMAC).仿真表明,该协议有效的节省了节点能耗,延长了网络节点的生存时间,同时还能够增大空间信道的利用率,从而进一步提高网络的平均吞吐量.

Proposes a comprehensive solution for multi-channel power control MAC protocol in Ad Hoc networks. By adaptively ad- justing the required transmission power for data packets and route request packets, the protocol allows for more interference-limited simultaneous transmissions to take place in the neighborhood of a receiving node via multi-channel. Simulation results indicate that the proposed protocol achieves a significant decrease in the total energy consumption while increase in the channel utilization and end to end network throughput.
