摘　　要：在6LoWPAN的DODAG网络路由拓扑中增加多网关功能和协议,有利于整个网络网际容量的提升以及节点能耗和负载的降低。以网关负载均衡为目标,同时考虑剩余能量和链路质量因素,提出一种适合于6LoWPAN网络的多网关部署算法。根据树型拓扑网络的负载累加特性,执行部署算法搜索候选网关并确定网关位置。仿真实验结果表明,该算法能够以与同等算法接近的网关数量实现较好的网关负载均衡。The addition of multi-gateway function and protocol in the Destination Oriented Directed Acyclic Graph(DODAG)network routing topology of 6LoWPAN is conducive to the improvement of the entire network capacity and the reduction of energy consumption and load of nodes.Aiming at gateway load balancing and considering the factors of residual energy and link quality,this paper proposes a multi-gateway deployment algorithm suitable for 6LoWPAN network.According to the load accumulation characteristics of the tree topology network,a deployment algorithm is executed to search for a candidate gateway and determine the location.Simulation results show that the algorithm can achieve better gateway load balancing with the number of gateways close to other algorithm.
