An Overlapping Routing Tree Transmission Model Based on Segment Identification: OTSI Model

Abstract

In the Internet of Things (IOT) based on IPv6. For large-scale multi-gateway WSN, the sensor device has its own certain limitations, and the processing capability of the node is very limited. Due to the limitations of the traditional WSN routing transmission protocol, this paper proposes an overlapping routing tree transmission model (OTSI) based on segment identifiers and a method to generate the model. We design a segment identifier based on the model, specifying transmission gateways and service demands for nodes in different manifestations of segment identifiers. We also designed a data transmission model of the OTSI in different scenarios. Through the OMNeT simulation experiment, it's found that the model can effectively specify the transmission gateway for the node according to the service demand, and achieve the balance of traffic transmission.
