Title Study on the Technology of Network Building based on Power Line Carrier Communication
Abstract
With the rapid development of network and information technology, power line carrier communication network technology arises more and more attraction. Among power line carrier communication network technology, the method of building dynamic network draws most attention. After the research on mainstream of power line network building，a lot of work has been down. After deep discussion about dynamic network theory and routing optimization algorithm, the characteristic of Genetic Algorithm, Simulated Annealing Algorithm, Ant Colony Algorithm and other algorithms has been analyzed. And Ant Colony Algorithm is adopted as the optimal one. The characteristic of power line carrier communication network is studied. And a reasonable network topology is founded. On the basis of NS2, we simulate the optimal routing algorithm based on Ant Colony Algorithm. Throughput, packet end-to-end delay are used as performance measures. The experimental results show that the mesh topology which consists of several ring topology has the best performance in power line carrier communication network.

1 绪论
电力线载波通信是利用电力线这种介质来进行载波传输的一种通信方式。电力线作为一种不用重新布线的基础设施，过去仅仅用于远程抄表、家居自动化，传输速率很低，不适合高速信息传输。随着网络技术和信息技术的迅猛发展，国内外正积极开展利用低压电力线传输速率在1Mbps信息的高速电力线载波技术。高速电力线载波通信技术在现有电力线上实现数据，语音和视频等多业务的传输，是充满了经济气息的一种不断进步的新技术。另外，随着“十一五”规划把电力线载波通信列入大力研究项目，电力线载波通信网络受到越来越多的人的关注。其中低压电力线载波通信的发展对策明确把研究电线网络的原理和应用，探讨电力线载波通信网络的政策和运营方式，努力为实现全面电力线载波通信网络打好基础作为发展重点。目前，高速电力线载波通信技术仍然没有得到大规模的使用，这与自身技术不完善有很大的关系。
