Un protocole de routage à basse consommation d'énergie pour les MANETs
摘要：
由于移动节点的电池容量有限，最大化网络寿命是移动自组网路由协议设计中的一个非常具有挑战性的问题。此外，在关键环境（例如战场、灾区等）中，更换电池或对电池充电通常是不可能的。长期以来，能源消耗被认为等同于带宽消耗。然而，最近的工作表明，“能量”和“带宽”是实质上不同的度量。此外，人们发现，传统的路由策略，如“最短路径”之一，可以有负面影响的能源消耗平衡。因此，已经提出了几种明确解决能源效率的新方法。我们的工作是关于能量有效路由的移动自组网问题。提出的MEA-DSR（多路径能量感知按需源路由）协议是基于移动节点之间的负载分担策略，以最大限度地提高网络的生命周期。为了实现这一目标，我们使用多路径路由，节点的剩余能量和路径长度也被考虑时，路由决策。仿真结果表明，所提出的协议的效率，在困难的情况下，其特点是高流动性，高密度和重要的流量负载。
英文摘要：
Maximizing network lifetime is a very challenging issue in routing protocol design for Mobile Ad-hoc NETworks (MANETs), since mobile nodes are powered by limited-capacity batteries. Furthermore, replacing or recharging batteries is often impossible in critical environments (e.g. battlefields, disaster areas, etc.). Energy consumption was considered for a long time equivalent to bandwidth consumption. However, recent works have shown that "energy" and "bandwidth" are substantially different metrics. Moreover, it was found that traditional routing policies such as "the shortest path" one can have a negative impact on energy consumption balance. Therefore, several new approaches have been proposed addressing energy efficiency explicitly. Our work is related to energy efficient routing for MANETs' problem. The proposed MEA-DSR (Multipath Energy-Aware on Demand Source Routing) protocol is based on a load sharing strategy between mobile nodes in order to maximize network lifetime. To achieve this goal, we used multipath routing; nodes' residual energies and paths length were also considered when making routing decisions. Simulation results have shown the efficiency of the proposed protocol under difficult scenarios characterised by high mobility, high density and important traffic load.
