| Networking technology is one of the foundations to the large scale WSNs. Network model and node location deployment is an important part of networking in WSNs. According to the characteristics of the large scale WSNs and the analysis in IoT needs, a new type of network model suitable was presented which combined the advantages of Star model and Mesh model. In the meantime after the improvement in the RDF algorithm through united density priority with neighbor information, the NDF algorithm that Suitable for network node deployment to large scale WSNs was presented which would be saved and prolonged the network life time. Tests showed that through the new network model and NDF algorithm to form a large scale WSNs networks for the IoT, complete real time monitoring and accurately data acquisition, and that to achieve the requirements on rapid and accurate data. |
