摘要:
 随着无线多媒体传感器网络的发展,单Sink节点网络逐渐难以满足多媒体信息传输的可靠性和实时性等要求,而多Sink节点网络可以有效减少数据平均传输距离、平衡网络整体能耗.针对多Sink节点的无线多媒体传感器网络,结合网络的服务质量(QoS)保障要求,提出了基于蚁群优化的QoS保障多径路由算法.该算法考虑网络的实时性、带宽、延迟等多QoS保障要求,基于改进蚁群算法,以路径的带宽、时延、丢包率及最小剩余能量等作为路径的评价指标,综合考虑Sink节点的负载能力,选择质量较高的路径进行数据传输,实现了QoS保障的多径路由算法.以OMNeT++和Matlab为平台,对所提出的算法进行了仿真验证与分析.仿真结果表明,所提出的算法能有效地平衡网络负载,降低网络丢包率,延长网络生命期.
Abstract:
 With the development of Wireless Multimedia Sensor Networks (WMSNs),the network of a single sink node is gradually difficult to meet the requirements of real-time and reliability.Multiple sink nodes network can effectively reduce the data average transmission distance and balance networks energy.A multi-path routing algorithm based on ant colony optimization has been proposed for multi-sink WMSNs according to the Quality of Service (QoS) requirements related to various applications,which takes several QoS requirements such as the bandwidth,end-to-end delay,packet loss,reliability and so on into account.Then a multi-path routing algorithm has been constructed with improved ant colony algorithm,which can evaluate a path with several QoS parameters and the capacity of the sink node.The simulations have been conducted with OMNet++ and Matlab.The results of experiment show that the new algorithm can effectively balance the traffic load,reduce packet loss probability and prolong the network lifetime.
