Abstract

For the IPv6-based Wireless Sensor Networks (WSN), there exists a difficulty in applying Internet protocol into Internet of Things (IoT) due to the constrained resources. Constrained Application Protocol (CoAP) is a lightweight protocol which is proposed and standardized by Internet Engineering Task Force (IETF). And it is designed for constrained environments, such as sensor nodes and sensor networks. However, there are some shortcomings for the CoAP proxying and cache scheme, e.g., without considering the topology changes adequately, and requiring a large cache space at proxy endpoints, etc. In order to address these issues, some improvement schemes on proxying and cache are proposed in this paper. The results verify that, through reducing the router throughput and time delay, the enhanced proxying and cache scheme can improve the network performance effectively.
