TinyCoAP: A Novel Constrained Application Protocol (CoAP) Implementation for Embedding RESTful Web Services in Wireless Sensor Networks Based on TinyOS

Journal of Sensor and Actuator Networks, 2013
In this paper we present the design and implementation of the Constrained Application Protocol (CoAP) for TinyOS, which we refer to as TinyCoAP. CoAP seeks to apply the same application transfer paradigm and basic features of HTTP to constrained networks,

CoAP over BundleProtocol

This work focuses on the study and implementation of the CoAP application layer over the Bundle layer in a network architecture based on DTN. The objectives of the project are the correct transmission of CoAP packets through a DTN network with persistent storage. A practical study was conducted on implementing the CoAP application layer over the Bundle
