摘要
分析了电力线载波通信中集中式路由的瓶颈现象,为缓解这一现象,提出了k-重传机制。通过构建k-重传机制的模型,分析证实了在集中式路由策略中引入该机制能够有效提高路径可靠性和降低主节点期望等待时间。
Concentrated routing is a basic ,simple ,necessary and popular routing method in the system networked via Power Line Communication (PLC). This paper analyze the performance bottleneck arisen in the concentrated routing process employed in PLC networks. In order to alleviate this negative phenomenon, propose a mechanism called k-repeat to be used in packet travel. The analysis show that the k-repeat mechanism, in term of the expected time to complete a communication task, can greatly im- prove the performance of concentrated routing in PLC networks.
