Analysis of routing and security issues in OLSR protocol for video streaming over MANET

Abstract

Mobile ad-hoc networks (MANETs) are autonomous, self-organizing networks without infrastructure support. The nodes in MANET network are dynamic and these nodes create creates a topological map through exchange of routing information defined by some set of rules called routing protocols which are further classified as proactive, reactive and hybrid. OLSR is proactive type of protocol which is widely used in MANET. The basic principal of OLSR is based on selection of Multipoint Relays (MPR) through flooding mechanism. There have been many enhancements in OLSR routing protocol to improve routing and security issues. But there is still a very vital scope for enhancement in OLSR to overcome these issues. In this paper, we review the different enhancements in OLSR and attempt to find out different routing and security challenges that can be further enhanced in OLSR for video streaming over MANET
