Abstract: This paper focuses on the issue of QoS routing problem in medium and high rate sensor networks. The corresponding model is set up and analyzed. An improved ant colony optimization algorithm to QoS routing problem is introduced. It guarantees that different services have different QoS parameters in medium and high rate sensor networks. Reverse inhibition is set to ensure the service with higher priority can obtain more resorces. Simulation results show that improved routing protocol is suitable for medium and high rate sensor networks, which can meet different QoS requirements of different services.

Key words: medium and high rate sensor networks, QoS guarantee technology, ant colony optimization algorithm

摘要： 通过对中高速传感器网络的QoS路由算法问题进行建模和分析，提出一种改进的基于蚁群优化算法的QoS路由算法，以满足网络中多种混合服务对QoS质量的不同要求。利用反向抑制机制优先保证高优先级别服务的QoS要求。仿真结果表明，该路由协议可以满足中高速传感器网络对不同业务的QoS需求。
