A Comparative Study of Mobile Ad-Hoc Network Protocols

Mobile Ad hoc networks are wireless network that use multi-hop routing instead of static networks infrastructure to provide network connectivity. The network topology in MANETs usually changes with time. Therefore, these are new changes for routing protocol in MANETs since traditional routing protocols may not be suitable for MANETs. In mobile Ad-hoc network, the reactive and proactive routing protocols face many challenges like frequently changing topologies increases random number of nodes, connection brakes etc. For facing these types of challenges, this paper evaluates a lot of reactive and proactive routing protocols. This work is an attempt towards a comprehensive performance evaluation of five commonly used Mobile Ad hoc routing protocols . In this paper, we studied and compared the performance of various routing protocols like Ad hoc (AODV), (DSR), (TORA), (DSDV), (OLSR). In this paper few of the on demand ad hoc protocols are introduced and compared in order to find out for which kind of networks protocol is most suitable.
