将图的染色理论与合作博弈论相结合,建立起一个理性节点的收益模型,然后基于此模型提出了一种适用于无线多媒体传感器网络的节点不相交多路径路由算法,算法采用源路由方式建立,中间节点基于节点收益对路由请求消息进行转发,目的节点回复路由答复消息,源节点收到答复消息后迅速建立到目的节点的路由.该算法不仅能够建立质量更好的多路径,还能够平衡网络节点的能耗,从整体上达到多路径路由建立和优化的目的.仿真结果表明:与SMR,Tin-yONDMR算法相比,利用该算法所建立的多路径在数据传输时具有更高的能量效率,网络中节点的能量分布更理想.
Based on the combination of stained graph theory and cooperative game theory, a profit model of rational nodes is established. Based on this model, a node disjoint multipath routing algorithm for wireless multimedia sensor networks is proposed. The algorithm uses source routing to establish , The intermediate node forwards the route request message based on the node profit, and the destination node replies the route reply message, and the source node quickly establishes the route to the destination node after receiving the reply message. This algorithm can not only establish a better quality multi-path but also balance The energy consumption of network nodes achieves the goal of multipath routing establishment and optimization as a whole.The simulation results show that compared with SMR and Tin-yONDMR algorithms, the multipath established by this algorithm has higher energy in data transmission Efficiency, the energy distribution of nodes in the network is more ideal.
