为了减少网络能量消耗,优化网络性能,在网络节点MAC层发射功率可控条件下,提出了一种基于平均分组时延与分组能量消耗乘积最小的路由路径选择算法.该算法根据链路平均分组时延和分组能量消耗情况来进行路由路径选择.仿真表明,该算法可以动态调整网络路由路径,使所选路径的平均分组时延与分组能量消耗乘积达到最小,从而达到减少网络能量消耗及降低网络分组时延目的.

In order to save the network energy and optimize the network performance, under the emission power of node being controllable, a routing path selection algorithm based on the minimal product of packet delay and packet energy consumption is presented. The algorithm is based on packet delay and energy consumption in selecting routing path. Simulation results show that the presented algorithm can dynamically adjust the routing path, which can make the product of packet delay and energy consumption of routing path minimized in Ad hoc networks.
