A dynamic load balancing algorithm for wireless mesh networks based on network calculus

To make ensure the quality of service of wireless Mesh networks and improve network performance, this paper aims at the problem of load imbalance caused by several existing main wireless Mesh network load balancing algorithms without fully considering the backbone network nodes and link states. A dynamic load balancing algorithm based on network calculus. First, use the depth-first traversal algorithm to construct available paths; then, establish the queuing delay and data backlog model of nodes, and combine the comprehensive calculation of path reliability with nodes and links to obtain a set of reliable paths; finally, calculate the allocation data of different paths The weight of the packet, and distribute data packets on demand according to the weight. Simulation results show that compared with traditional AODV protocol, HWMP protocol and improved LB-HWMP protocol, the algorithm proposed in this paper is superior in delay and throughput.
