摘要:

根据最大独立集和首次适应算法,设计了一种基于牡丹树的数据聚合算法.在基于牡丹树的数据聚合算法的基础上,采用时分复用方法,在聚合周期时隙内引入低能耗的睡眠调度的概念,从很大程度上减少了数据传输量,降低了网络聚合时延,实现了低能耗的数据聚合.实验与仿真结果表明,新算法有效地降低了网络能耗,延长了网络生命周期,减少了网络时延消耗.

Abstract:

Based on the maximum independent set and first-fit algorithm, we design a data aggregation algorithm, Peony-tree-based Data Aggregation (PDA). On the basis of the PDA, using the time-division multiplexing method, we introduce the concept of low-power sleep schedule in the cyclical time slot of data aggregation. It is largely possible to reduce the amount of data transmission,network time delay and achieve low-power data aggregation. Simulation results show that the proposed algorithm can reduce network energy consumption, prolong the network lifetime and reduce the network delay cost.

Key words: wireless sensor network, data aggregation, sleep scheduling, delay cost
