【摘要】：针对间断连接无线网络节点能量受限特性,提出一种带有动态反馈的自适应异步节能机制,以解决节点在空闲侦听中能耗过大的问题;并在此基础上,设计了一种能够根据网络通信错失率和节点能耗动态反馈调整的占空比机制,以有效延长生命周期,提升网络的投递性能。数值结果表明,与同类自适应节能机制相比,所提机制能够在不损失网络投递性能的情况下,极大限度地延长网络和节点的生命周期。
[Abstract]:An adaptive asynchronous energy saving mechanism with dynamic feedback is proposed to solve the problem that nodes consume too much energy in idle listening. A duty cycle mechanism which can be adjusted according to network communication miss rate and node energy consumption dynamic feedback is designed in order to prolong the life cycle effectively and improve the delivery performance of the network. Numerical results show that compared with the similar adaptive energy saving mechanism, the proposed mechanism can greatly prolong the lifetime of the network and nodes without losing the network delivery performance.
