一种双层树型高能效多链路由算法
A Two-Layer Tree-Type Energy Efficient Multi-Link Routing Algorithm
摘要
Abstract
In order to overcome the high maintenance cost of the single-link of the PEGASIS protocol algorithm,and solve the defects of the COSEN protocol algorithm such as the large number of cross-links and long-links,data reverse transmission,a two-layer tree-type energy efficient multi-link routing algorithm(TTEMR) is proposed. TTEMR algorithm divides the network nodes into two layers, the bottom layer constructs the network nodes into multiple sublinks, then select the main link-leader and the sub-link-leaders to construct the top layer link-leader link. To reduce the length of the data transfer path,handling isolated points using a tree structure during the linking process,optimizing the selection strategies of the main link-leader and the sub-link-leaders and the link-forming rules,and avoid common nodes and sub-link-leaders near the Sink node into the link to reduce the reverse transmission of data. Simulation results show that compared with LEACH,PEGASIS and COSEN algorithm,TTEMR algorithm excels in the performance of each round of nodes, the stability period and life cycle of the network, the total energy remaining in each round,and the average path length per unit link segment.关键词
