Porting CoAP on Sparrow v4
Dragan Dan-Stefan - Master AAC
Introduction
The Constrained Application Protocol (CoAP) is a web transfer protocol that is intended for use with reduced-capability, low-power devices. These nodes often have 8-bit microcontrollers with small amounts of ROM and RAM. CoAP provides a request/response interaction model between application endpoints, supports built-in discovery of services and resources, and includes key concepts of the Web such as URIs and Internet media types. This project uses an existing CoAP implementation over an IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) stack and its main goal was porting the existent environment on Sparrow v4.
General Overview
6LoWPAN is a networking technology or adaptation layer that allows IPv6 packets to be carried efficiently within small link layer frames. It has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent and received over IEEE 802.15.4 based networks.
