OMNeT++ based Opportunistic Routing Protocols Simulation: A Framework

This paper describes a framework for simulating opportunistic routing protocols in the INETMANET framework of OMNeT++. The proposed modules adopt an abstraction of the generic functions of the most representative opportunistic routing algorithms. The main contribution is an OMNeT++ modeling architecture that could be extended to implement different opportunistic routing schemes. Our work provides an analysis of the most representative opportunistic routing algorithms. We decouple the opportunistic routing schemes into four procedures Forwarder Candidate Selection, Forwarder Selection, Forwarder Role Change Notification and Collision Avoidance. Different protocols should have specific implementations of each procedure. In the framework, these four procedures are defined as virtual functions and act as implementation stubs such that different protocols could be implemented by overriding them in the derived function according to their distributed strategies.
