Multipath Transmission Based on Heterogeneous Wireless Network

Zhang Wei;Ma Xiao;Wang Yu;School of Physics and Information Technology, Shaanxi Normal University;  
Aiming at the problem of unreliable transmission of large capacity services and low utilization of network resources in heterogeneous wireless networks, this paper proposes a multi-path routing algorithm based on heterogeneous wireless ad hoc networks. The algorithm effectively avoids the congestion and low throughput of the transmission link under the single communication mode. Based on the characteristics of the large-capacity service, the algorithm can reasonably characterize the network environment information by certain rules and the end-to-end multipath Strategy so that services of different importance can be selected to be transmitted in parallel along the path of the corresponding link quality to avoid that it is difficult for the source node to obtain the routing information of the intermediate node caused by each node in the network independently finding the route. The simulation results show that the algorithm can achieve the entire network load balancing, alleviate the network link congestion, reduce the transmission packet loss rate and reduce the transmission delay.
