摘 要: 无线传感器网络要求支持多种业务的差别服务和全网范围的资源有效利用,服务质量(quality of service, QoS)路由是解决该问题的关键技术之一。在分析无线传感器网络QoS路由问题的基础上,将现有的蚁群算法进行扩展,提出了一种组合利用路径节点最少能量和最小跳数信息的分布式QoS路由算法,并建立了仿真模型,仿真结果表明:与传统QoS路由算法相比,在不同比例的混合业务模式下,该算法可以很好地支持不同业务的资源需求分配,达到全网能耗均衡。此外,对无线传感器网络也具有较好的适应性。
关 键 词: 计算机系统结构;无线传感器网络;服务质量;网络模型;蚁群算法

Abstract: Wireless sensor networks are required to support diversiform business of differential services and efficient using resources in the whole network. QoS routing is one of the key technologies to resolve this problem. On the basis of analyzing problems of QoS routing in wireless sensor networks, this paper expands the existing ant colony algorithms, brings up one kind of distributed QoS routing algorithms which can combine minimum nodes’ energy in the path with the smallest hops, and also builds the simulation model. The simulation results indicate that the algorithm can support the different needs of resources distribution well and keep the balance of energy consumption in all the networks compared with the traditional QoS routing algorithms. Besides, the algorithm also has great adaptation for the wireless sensor networks.
