针对网络节点负载不均衡、节点能量消耗较大、网络吞吐量较低的问题,提出基于多跳分簇算法的异构融合通信网络节点负载均衡方法。依据异构融合通信网络实时(RT)和非实时(NRT)业务的服务质量满意度,应用效用函数结合三角模融合算子,将重载网络通信业务转移至轻载网络,实现异构融合通信网络业务负载均衡;运用多跳分簇路由算法,依据节点位置和其所剩能量选取簇头,通过减少网络边缘的簇头数量,节省网络能量消耗,通过簇头节点剩余能量和链路权值大小选取下一路由,构建簇间路由通信机制,实现异构融合通信网络节点负载均衡。在实验验证方面,在5.5×15^(3)个周期时,存货节点为0,吞吐量最高可达到13.5×15^(4)bit,出色地完成异构融合通信网络节点负载均衡,合理选取簇头节点,减少节点能量的消耗,提升节点生存周期和网络吞吐量。

Aiming at the problems of unbalanced load,high energy consumption and low network throughput of network nodes,a load balancing method of heterogeneous fusion communication network nodes based on multi-hop clustering algorithm is proposed.According to the service quality satisfaction of real-time(RT)and non-real-time(NRT)services in heterogeneous converged communication networks,the utility function combined with the triangular norm fusion operator is applied to transfer the heavy load network communication services to the light load network to achieve the service load balance of heterogeneous converged communication networks.The multi-hop clustering routing algorithm is used to select cluster heads according to the node location and its residual energy.By reducing the number of cluster heads at the edge of the network,the network energy consumption is saved.The next route is selected through the residual energy of the cluster head node and the size of the link weight,and the inter cluster routing communication mechanism is constructed to achieve the load balance of heterogeneous fusion communication network nodes.In terms of experimental verification,in 5.5×15^(3) cycles,the inventory node is 0,and the maximum throughput can reach 13.5×15^(4) bit,which can achieve outstanding load balancing of heterogeneous converged communication network nodes,reasonably select cluster head nodes,reduce node energy consumption,and improve node life cycle and network throughput.
