摘要
移动自组网是由一组带有无线收发装置的移动节点组成的一个支持多跳的临时性的网络自治系统。由于移动自组网的大多数节点是由有限寿命的电池来提供的,因此能量保护策略成为制定路由协议的一个重要依据。该文提出了一种新的基于动态源路由协议的节能路由策略,仿真表明该策略有效地延长了网络的生存时间,并很好地均衡了节约能耗和保护网络传统性能的需求。
MANET (mobile ad hoc network) is multi-hop wireless network that is composed of mobile hosts communicating with each other through wireless links. Efficient energy conservation plays an important role in the performance of MANET because mobile nodes in such networks are usually battery-operated. A new DSR-based energy saving routing strategy is proposed and analyzed in this paper. Simulations show it maximizes the lifetime of network, and trades off the energy saving and conventional network performance.
