Design-and-Implementation-of-Adaptive-CoCoA++

Course Code - CO365

An attempt to design and implement Adaptive CoCoA++

Overview

CoAP is a wide application layer protocol used on top of UDP to ensure reliability in IoT network. It used exponential backoff. CoCoA and CoCoA+ used the information from the network i.e. RTT to calculate RTO and accordingly backoff. CoCoA++ is another modification that uses the concepts of CDG to do the backoff.

Approach

Studied CoAP,CoCoA,CoCoA+,CDG.
Documented understanding.
Took the implementation of CoCoA++ from mentor.
Understood it and ran various experiments on it & recorded the results.
Proposed a mechanism to make the backoff adaptive.
Implemented the algorithm and used fixed point arithmetic to do so.
Tested the algorithm and obtained the results.
