一种基于排序蚁群算法的无线Mesh多径路由协议

无线Mesh网络因其较好的鲁棒性、可覆盖区域广、低成本、接入便利等优点,在临时布置通信网络逐渐得到了重用,在无线通信技术中扮演着越来越重要的角色。针对无线Mesh网络的特点,提出一种基于改进蚁群算法的多径路由协议Fortified Ant协议。与传统的蚁群算法路由协议相比,该协议对蚁群算法进行改进,在蚁群算法基础上加入排序算法,同时在该协议中加入多径传输,在主路由失效时马上启用备份路由,保证信息传输的时效性和可靠性。实验结果表明,与ADOV、DSR和ACO路由算法相比,该算法能迅速发现质量较优的多条路径,具有收敛快、开销少等优势。

Wireless Mesh Multipath Routing Protocol based on Sorted Ant Colony Algorithm

Due to its advantages such as good robustness,wide coverage,low cost and convenient access,wireless mesh network is gradually being reused in temporary communication networks and plays an increasingly important role in wireless communication technologies.Aiming at the characteristics of wireless mesh networks,a multi-path routing protocol based on an improved ant colony algorithm is proposed,namely the Fortified Ant protocol.Compared with the traditional ant colony algorithm routing protocol,this protocol improves the ant colony algorithm,adds a sorting algorithm on the basis of the ant colony algorithm,and at the same time,the multi-path transmission to the protocol.When the main circuit fails,the backup route is immediately enabled to ensure the timeliness and reliability of information transmission.Experimental results show that compared with ADOV,DSR,and ACO routing algorithms,this algorithm can quickly find multiple paths with better quality,and has the advantages of fast convergence and low cost.
