Simulation Tools for Opportunistic Networks

Abstract

The Opportunistic Network (OppNet) is an emerging approach nowadays for different applications like space communication, wildlife tracking, satellite communication, etc. Such a network can support longer delays and infrastructure-less patterns of communication. The real-time implementation of opportunistic networks is very expensive and quite complex. So, the only way to observe the performance of different scenarios of OppNets is to use simulation software and tools. Some tools are available to implement the scenario of OppNets, e.g., Opportunistic Network Environment (ONE), Network Simulator-2 (NS-2), OPNET, and OMNet++. In this chapter, the implementation of OppNets using the ONE simulator for different parametric settings will be discussed. Here, we will summarize how to install and run the ONE simulator and then how to set up different settings for different scenarios and analyze the results from the simulated values. Moreover, we exhibit step-by-step simulation settings for different scenarios, e.g., the variation of message copies, number of nodes, buffer size, and TTL, and discuss their impact on delivery ratio, delay, overhead, average hop count, and buffer time.
