摘要
为了研究水下传感器网络多址接入(MAC)协议的能量损耗,在集中式拓扑结构下,对ALOHA和MACAW两种协议的能量效率进行了理论分析,并通过Matlab进行了仿真。结果表明:通过改进的MA-CAW协议在网络节点数较多,数据到达率较高,数据包较大的网络中比ALOHA协议具有更高的能量效率。
To study the energy loss of the MAC protocol for underwater sensor networks,the energy efficiency of the ALOHA and MACAW are analyzed and simulated based on Matlab in centralized topology.The results show that the improved MACAW protocol has much higher energy efficiency than ALOHA protocol in network which has more nodes,data arrival rate and larger packet size.
