【摘要】 提出了一种移动自组织网络中能量有效的跨层协议,将网络层的能量感知路由协议与MAC层的功率控制协议相结合,以提高节点的能量利用效率.在路由协议中根据节点剩余能量决定节点接入路由的延迟时间,从而使剩余能量较多的节点能够更快地接入路由,以使网络中的能量消耗更公平.在MAC层中实现功率控制,减少节点的实际能量消耗.仿真结果表明,在移动自组织网络中,该能量有效的跨层协议不但能延长网络的生存时间,减少端到端延迟,而且可以提高网络吞吐率.更多还原

【Abstract】 An energy-efficient cross-layer protocol is presented for mobile ad hoc networks.A new energy-aware routing protocol is integrated with a power control MAC(medium access control) protocol to improve the energy efficiency of the nodes.In network layer,nodes choose the jitter delay based on their current energy levels,so that the nodes with more remaining energy enter the route more quickly and energy consumption in the network can be fairer.Power control in MAC layer effectively decreases the real energy consumption of the nodes.The simulation results indicate that the proposed protocol in mobile ad hoc networks can prolong the network lifetime,decrease the end-to-end delay and improve the network throughput ratio.更多还原
