基于牛顿插值的MANET能量有效路由机制

Power-aware routing mechanism based on Newton's interpolation in MANET

移动AdHoc网络中的一个主要问题是节点的能量有限。因此,许多研究侧重于减少能量消耗。提出一种基于牛顿插值的能量有效路由机制,首先根据节点的剩余电池能量和流经该节点的当前流量大小,计算出该节点的寿命;从寿命较长的节点中,选择当前状态下的最小功率路由。这样不仅保证了各节点的能量均衡问题,而且考虑到整个网络的最小功率路由。实验模拟结果显示,与以前算法相比,其具有更好的性能。

One main constraint in Mobile Ad Hoc Network （MANETs） is limited by the power of the node. Therefore, much effort has been paid to reduce power consumption. A new power-aware routing mechanism is presented based on Newton＇s interpolation. According to the remaining energy and the traffic load at nodes, the life of the nodes was calculated out, and then from the bearable life of nodes, one minimum power drain routing can be choused. In this way, the mechanism not only takes account of the balance of the power at nodes, but also pays attention to the minimum power drain routing problem of the whole network. Simulations show that, compared to previous algorithms, it has better performance.
