【摘要】 融合延迟分配策略是影响数据融合效率的重要因素之一,而数据融合的目的是减少数据冗余,降低网络能量消耗,延长网络生存时间.提出了一种面向网络生存时间的延迟分配算法,该算法直接以网络生存时间为优化目标,根据对网络生存时间的贡献分配传输延迟;通过理论推导证明了该算法的有效性;引入动态规划方程,给出了该算法的具体实现;最后通过仿真实验给出了各参数对网络生存时间的影响关系.
【Abstract】 Transmission delay distribution strategy is one of the important factors influencing the data fusion efficiency,and the purposes of data fusion is to reduce data redundancy,reduce network energy consumption and prolong network life span.A network life span-based delay distribution algorithm is presented in this paper.This algorithm directly takes the network life span as the optimized goal,according to the different contribution to the network life span to distribute transmission delay;theoretical analysis demonstrates the effectiveness of the algorithm;dynamic programming equation is introduced to show the realization of the algorithm;and finally various parameters which reflect the different effects on network life span are given through simulation experiments.
