摘　　要：针对移动自组网中不同种类业务QoS保障问题,提出基于蚁群优化的混合多路径QoS路由协议(HMQ-ACO),该协议融合了反应式路由建立与主动式路由维护的策略并支持多路径,根据多约束QoS条件建立目标函数,并基于该目标函数设计信息素更新机制,同时考虑节点拥塞度和费用,利用蚁群优化算法寻找满足带宽、时延、丢包率约束的路径集合,依据目标函数值选择合适路径。仿真结果表明,所提出的协议在端到端时延、分组传递率方面优于其他传统路由协议。To address the quality of service(QoS)guarantee issues of different types of services in mobile ad hoc networks,a hybrid multipath QoS routing protocol based on ant colony optimization(HMQ-ACO)is proposed.This protocol integrates reactive route establishment and proactive route maintenance strategies and supports multipath.An objective function is established based on multi-constraint QoS conditions,where a pheromone update mechanism is designed.Meanwhile,taking into account node congestion and cost,the ant colony optimization algorithm is used to find a set of paths that meet bandwidth,delay,and packet loss rate constraints,and appropriate paths are selected based on the objective function value.The simulation results show that the proposed protocol outperforms other traditional routing protocols in terms of end-to-end latency and packet delivery rate.
