【摘要】：隨著信息通信技術(shù)的飛速發(fā)展,移動多跳無線網(wǎng)絡(luò)已經(jīng)成為無線通信中的一種重要通信方式,其重要性隨著現(xiàn)今研究的深入得到越來越多的重視。近年來,移動多跳無線網(wǎng)絡(luò)中的流量呈指數(shù)持續(xù)增長,隨之帶來的結(jié)果是網(wǎng)絡(luò)設(shè)備的能耗驚人的遞增,根據(jù)最新相關(guān)的統(tǒng)計數(shù)據(jù)表明,通信業(yè)每年消耗的電能達兩百多億度以上,耗電總量在各行業(yè)中排名呈現(xiàn)持續(xù)上升的趨勢,且其中能耗的一半以上來自于移動多跳無線網(wǎng)絡(luò)的能量消耗。因此,研究如何大幅度提高移動多跳無線網(wǎng)絡(luò)能效的傳輸技術(shù)與理論,已經(jīng)成為了當前無線通信領(lǐng)域里的前沿課題。然而目前針對移動多跳無線通信網(wǎng)絡(luò)環(huán)境的研究,還沒有統(tǒng)一的能效度量標準和能效模型,本文通過分析無線通信的能耗模型,然后考慮其在傳輸過程中存在一定的誤碼率這一特性,提出了相應(yīng)的能效度量標準和能效模型,以及相應(yīng)的能效路由算法。首先,本文研究了無線通信能耗的基本模型,并考慮了傳輸過程中存在誤碼率這一特性,提出了靜態(tài)條件下多跳無線網(wǎng)絡(luò)的能效度量和能效模型,進而最后提出了本文的能效路由算法。近年來,研究高能效的路由算法,是解決目前無線通信傳輸高能耗、低效率的重要手段之一。很多學者已經(jīng)對此進行了大量深入細致的研究,并提出了相應(yīng)不同的能效度量標準,然而很多設(shè)計模型考慮卻并不夠細致,僅僅考慮了能量消耗一個方面的代價,并沒有充分考慮其路由的傳輸時延及其傳輸?shù)目偩嚯x等代價參量,同時也沒有考慮誤碼傳輸?shù)膶嶋H情況,從而導致能效模型不能更好的體現(xiàn)出網(wǎng)絡(luò)的性能及其路由算法的有效性,本文仔細考慮了傳輸過程中路由上傳輸時延及其傳輸?shù)目偩嚯x等因素,提出了基于誤碼率的綠色能效度量模型,然后在此基礎(chǔ)上提出了基于能耗均衡的能效路由算法,仿真結(jié)果表明,本文所提的能效度量模型能進一步真實的反映出網(wǎng)絡(luò)性能及節(jié)點的傳輸效率,同時本文所提的能效路由算法能夠明顯的提高網(wǎng)絡(luò)的能效性能。其次,針對移動多跳無線網(wǎng)絡(luò)中節(jié)點和鏈路具有動態(tài)性和隨機性等變化特性,其結(jié)果造成網(wǎng)絡(luò)的能耗過高以及節(jié)點傳輸?shù)男蔬^低的這一問題。本文通過分析無線通信的信道容量模型,傳輸速率與信噪比的關(guān)系,進而得到其與發(fā)射功率的聯(lián)系,再結(jié)合傳輸時存在誤碼率這一特性,提出了基于網(wǎng)絡(luò)節(jié)點和鏈路動態(tài)變化以及傳輸存在誤碼率的條件下的綠色能效度量模型,在此模型基礎(chǔ)上,結(jié)合傳輸?shù)膶嶋H情況,通過考慮路由上的傳輸時延以及能耗,提出了基于最小時延能量積的能效路由算法,仿真結(jié)果表明,本文提出的綠色能效度量模型能更加符合實際的動態(tài)情形,更好體現(xiàn)出網(wǎng)絡(luò)性能及節(jié)點的傳輸效率,同時提出的能效路由算法能夠明顯的提高網(wǎng)絡(luò)的能效性能。
[Abstract]:With the rapid development of information and communication technology, mobile multi-hop wireless network has become an important communication mode in wireless communication. In recent years, the traffic in mobile multi-hop wireless network has been increasing exponentially, and the result is that the energy consumption of network equipment is increasing dramatically, according to the latest relevant statistics, The electric energy consumed by the communication industry is more than 20 billion degrees each year, and the total power consumption in each industry shows a rising trend, and more than half of the energy consumption comes from the energy consumption of the mobile multi-hop wireless network. Therefore, the research on the transmission technology and theory of how to improve the efficiency of mobile multi-hop wireless networks has become a frontier topic in the field of wireless communication. However, there is no unified energy efficiency measurement standard and energy efficiency model for mobile multi-hop wireless communication network environment. This paper analyzes the energy consumption model of wireless communication. Then, considering that there is a certain bit error rate in the transmission process, the energy efficiency metric, energy efficiency model and the corresponding energy efficiency routing algorithm are proposed. Firstly, this paper studies the basic model of wireless communication energy consumption, and considers the characteristic of bit error rate (BER) in the transmission process, and puts forward the energy efficiency measurement and energy efficiency model of multi-hop wireless network under static condition. Finally, the energy efficiency routing algorithm is proposed. In recent years, the research of efficient routing algorithm is one of the most important methods to solve the problem of high energy consumption and low efficiency in wireless communication. Many scholars have done a lot of intensive research and put forward different energy efficiency metrics. However, many design models are not careful enough to consider the cost of energy consumption. The cost parameters such as the transmission delay and the total distance of the route are not fully considered, and the actual situation of the error transmission is not taken into account. As a result, the energy efficiency model can not better reflect the performance of the network and the effectiveness of the routing algorithm. In this paper, the factors such as the transmission delay and the total distance on the route are carefully considered. A green energy efficiency metric model based on bit error rate (BER) is proposed, and then an energy efficiency routing algorithm based on energy balance is proposed. The simulation results show that, The energy efficiency metric model proposed in this paper can further reflect the network performance and the transmission efficiency of nodes, and the energy efficiency routing algorithm proposed in this paper can significantly improve the energy efficiency performance of the network. Secondly, the dynamic and random characteristics of nodes and links in mobile multi-hop wireless networks are discussed, which results in the high energy consumption and low transmission efficiency of nodes in mobile multi-hop wireless networks. By analyzing the channel capacity model of wireless communication and the relation between transmission rate and signal-to-noise ratio, the relationship between transmission power and transmission rate is obtained in this paper. A green energy efficiency measurement model based on the dynamic changes of network nodes and links and the presence of bit error rate (BER) in transmission is proposed. Based on this model, considering the transmission delay and energy consumption in routing, combined with the actual situation of transmission, An energy efficiency routing algorithm based on minimum delay energy product is proposed. The simulation results show that the proposed green energy efficiency metric model is more suitable to the actual dynamic situation and better reflects the network performance and the transmission efficiency of nodes. At the same time, the proposed energy efficiency routing algorithm can significantly improve the energy efficiency performance of the network.
