【摘要】：近年來,無線傳感器網(wǎng)絡(luò)技術(shù)得到了飛速發(fā)展和廣泛關(guān)注。作為影響傳感器網(wǎng)絡(luò)性能的一個核心因素,網(wǎng)絡(luò)的能耗問題己成為當(dāng)前的研究熱點(diǎn)之一。本論文重點(diǎn)研究了與無線傳感器網(wǎng)絡(luò)節(jié)能相關(guān)的兩個方面的問題：節(jié)點(diǎn)能耗問題及能量感知路由問題,提出了相應(yīng)的模型和算法,并進(jìn)行了仿真驗(yàn)證與分析。 首先,文章研究介紹了無線傳感器網(wǎng)絡(luò)的網(wǎng)絡(luò)體系結(jié)構(gòu)及標(biāo)準(zhǔn)化進(jìn)程。第二,研究介紹了無線傳感器網(wǎng)絡(luò)現(xiàn)有的路由協(xié)議,并對它們的優(yōu)缺點(diǎn)進(jìn)行了對比分析。第三,為了降低傳感器節(jié)點(diǎn)能量消耗,提出一種基于DVS和DMS協(xié)作的節(jié)能技術(shù)。該技術(shù)采用了預(yù)測機(jī)制,通過對日志數(shù)據(jù)的分析處理,估算傳感器節(jié)點(diǎn)的微處理器及無線電傳輸設(shè)備的負(fù)荷,從而實(shí)現(xiàn)DVS和DMS很好地協(xié)作。仿真結(jié)果表明,相比未使用任何節(jié)點(diǎn)節(jié)能技術(shù)的傳感器,提出的方法能夠?qū)崿F(xiàn)節(jié)點(diǎn)節(jié)能高達(dá)40%左右。第四,提出具有三個不同的版本路由算法——OPA。該算法采用負(fù)載均衡技術(shù)及網(wǎng)絡(luò)的能量估算技術(shù),通過平均在每個傳輸輪的最大歸一化能量而進(jìn)行路徑選擇。最后,對三個版本的OPA進(jìn)行了算法描述和實(shí)驗(yàn)仿真。仿真結(jié)果表明,提出的算法的性能優(yōu)越,能大幅度地提高網(wǎng)絡(luò)的生命周期及匯聚節(jié)點(diǎn)收到的數(shù)據(jù)包數(shù)量。
[Abstract]:In recent years, wireless sensor networks (WSN) technology has been rapidly developed and widely concerned, as a core factor affecting the performance of WSN. The energy consumption of wireless sensor networks has become one of the current research hotspots. This paper focuses on two issues related to energy saving in wireless sensor networks: node energy consumption and energy-aware routing. The corresponding model and algorithm are put forward, and the simulation results are verified and analyzed. Firstly, this paper introduces the network architecture and standardization process of wireless sensor networks. Secondly, it introduces the existing routing protocols of wireless sensor networks. And their advantages and disadvantages are compared and analyzed. Third, in order to reduce the energy consumption of sensor nodes, a energy-saving technology based on DVS and DMS cooperation is proposed. Through the analysis and processing of log data, the load of microprocessor and radio transmission equipment of sensor node is estimated, so that DVS and DMS can cooperate well. The simulation results show that. Compared with the sensor without any node energy saving technology, the proposed method can realize the node energy saving up to 40%. 4th. In this paper, three versions of routing algorithm, OPA, are proposed. The algorithm uses load balancing technology and network energy estimation technology. Path selection is made by averaging the maximum normalized energy of each transmission wheel. Finally, three versions of OPA are described and simulated. The simulation results show that the proposed algorithm is superior in performance. It can greatly increase the lifetime of the network and the number of packets received by the convergence node.
