In order to improve smart home’s wireless control measure and overall level of smart home, the current concerned problem is to design a wireless network protocol that is low-cost, easy to develop and oriented to the field of smart home. The paper puts forward the general framework of smart home’s wireless control on smart home’s wireless control protocol and specific applications, and designs hardware and network structure for this system. By combining with design and algorithm implementation of repeaters, the paper improves WSN routing protocol, which is based on applications of smart home, and geographical routing protocol, which is appropriate for this scene. Meanwhile, the paper applies double bounce greedy algorithm and routing void mark to improve the problem of routing void. In this way, it avoids from the generation of routing void to the greatest extent. Through the simulation experiment, it can draw a conclusion that comparing with GPSR protocol and GEAR protocol, the improved protocol has a great improvement on node energy consumption and effective avoidance of routing void. It makes network performance improve to a greater degree. Before deploying smart home’s network nodes, it should pay more attention to deploy the number of nodes. In appropriate node deployment, better network performance of smart home can be obtained.
