【摘要】:為了在無線多媒體傳感器網(wǎng)絡(luò)WMSNs通信中提供QoS支持,研究了WMSNs最小能耗實時路由算法問題。首先,定義了數(shù)據(jù)融合的概念及其在路由設(shè)計中的作用,在此基礎(chǔ)上設(shè)計了一個最小能耗實時路由算法LERTR,用于構(gòu)造WMSNs最小能耗實時路由樹。該算法首先使用ADH算法生成一棵最小能耗路由樹;若時延不滿足要求,則通過合并最小時延路徑來產(chǎn)生一個滿足時延約束的路由樹。仿真實驗表明:LERTR算法生成的路由樹在保障時延約束的情況下,具有很好的能耗代價性能。
[Abstract]:In order to provide QoS support for WMSNs communication in wireless multimedia sensor networks, the WMSNs minimum energy consumption real-time routing algorithm is studied. Firstly, the concept of data fusion and its role in routing design are defined. On this basis, a minimum energy consumption real-time routing algorithm, LERTR, is designed to construct the WMSNs minimum energy real-time routing tree. Firstly, the ADH algorithm is used to generate a minimum energy consumption routing tree. If the delay does not meet the requirements, a routing tree satisfying the delay constraints is generated by merging the minimum delay path. Simulation results show that the routing tree generated by LERTR algorithm has good energy consumption cost performance under the condition of guaranteeing delay constraints.
