基于功率约束及节点频谱选择的认知协同路由
Cognitive cooperative routing based on power constraints and node select spectrum
摘要
Abstract
This paper proposed a cooperative routing algorithm to enhance the efficiency of data transmission and optimize the energy load on cognitive radio network.Design of a collaborative network architecture based on collaboration between the cover technology and the underlying technology,the architecture provided a new spectrum policy choice for the network band performance diversification,to enhance the effectiveness of spectrum resources.Spectrum and node power allocation method of maximize link capacity was proposed by combining interference characteristics of collaborative network spectrum selection and according spectrum interference and power constraints.Spectrum utility parameter was introduced in collabo-rative routing design to optimize energy and transport efficiency of the routing nodes,while the metric parameters related to the residual energy and link capacity.Comparison simulation results show that effectively using channel access opportuni-ties,the algorithm could improve the transmission efficiency.Compared with the multicast routing method based on the competitive evolution algorithm,the cooperative routing algorithm has advantages respectively in increasing the success rate of data package transmission by 1.4%,increasing the average internet throughput by 8.4%,and increasing the average re-maining energy load by 3.2%,it also has a good performance in load balancing node.关键词
