Study of Routing Protocols in MANET
Mobile ad-hoc network (MANET) is a collection of wireless mobile devices which dynamically forms a temporary network without any support of central administration. The network is ad hoc because it does not rely on any pre-existing network infrastructure like routers in wired networks. Such networks have no fixed topology due to the high degree of node mobility. Node mobility may cause the routes change. Hence, routing in MANET is a critical task due to its highly dynamic environment. To accomplish routing, a variety of routing algorithms have been proposed and also modifications are made to these algorithms to improve its performance. These protocols fall in to mainly three categories---Proactive, Reactive and Hybrid. But, it is difficult to determine which protocol performs best under a number of different scenarios. This paper presents the qualitative comparison of selected proactive routing protocols DSDV, OLSR and CGSR based on security.
