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.
