【摘要】由于水下传感器网络能量非常有限,所以研究节能的水下传感器网络通信协议具有非常重要的现实意义。为了节省数据传输过程中消耗的能量,文中在S-MAC协议的基础上,设计了一种新的节能MAC协议,在数据传输过程中,通过引进CA-ACK自适应机制,根据信道情况,自动选择No-ACK或Imm-ACK机制,通过减少ACK确认帧的数量,减少能量的消耗。理论分析和仿真实验结果表明,SE-MAC协议有效地减少了数据传输中的能量消耗,同时也提高了网络的吞吐量。?cause the energy of the underwater sensor networks is limited,studying the energy efficient MAC protocol for underwater sensor networks is very meaningful. In order to save the energy consumption in data transmission process,present a new type of energy ef-ficient MAC protocol based on S-MAC. In the process of the date transmission,introduce an adaptive CA-ACK mechanism,which can reduce the number of ACK frames by choosing No-ACK or Imm-ACK automatically,so the MAC protocol can reduce the depletion of energy. Theoretical analysis and simulation results show that SE-MAC protocol can reduce the depletion of the energy,at the same time, SE-MAC can improve the throughput of the network. 【总页数】4页(67-70)
