摘要
文献[1]中提出的分布式最小能量算法,整体能耗虽低但不能避免部分节点能量过度支出。同样,按照贪心策略,本文提出一个优化整体能耗、延长系统生存时间的改进算法。算法的核心思想是在减少整体能耗的情况下,均衡网络中各个节点的负载。
The paper introduces an improved distributed minimal power routing algorithm for sensor networks. Using the greedy method which is different from the one in [1], our algorithm has a trade-off between minimizing the total power consumption (which may drain critical nodes) and maximizing the minimal residual power of the network (which may use too much total power), and therefore maximizes the lifetime of the whole system .
