Optimal Configuration of Intercommunicate Coding in Adhoc Network

Abstract

Network coding has recently emerged as an effectivesolution for multicast and broadcast communications in ad hocnetworks. We focus on broadcast traffic and design a networkcoding-based scheme that we compare against simpler solutions,by using the network simulator ns-2. Indeed, while often thebenefits of network coding have been shown via theoreticalanalysis or in simplified simulation scenarios, our aim is to assessthe performance of network coding in ad hoc networks when arealistic MAC protocol is considered. Our results show that theperformance of network coding for traffic broadcasting stronglydepends on the network node density and on the generation size.In particular, network coding leads to significant gains in termsof end-to-end packet loss probability and protocol overhead only

When the average number of neighbors per node is higher than.
