Comparative Study of Proactive Routing Protocols for MANETs

Mobile Ad hoc Network is an infrastructure-less self-configuring network of nodes. Each node of this type of network can move independently in any direction and will change its links to other devices frequently. To communicate to one node to another one each node can act as both host as well as router at the same time and perform all the routing and state maintenance operations. Due to frequently topology changes routing have always been one of key challenges in Mobile Ad hoc Networks and become more difficult when network size increases. In this paper we survey some multipath proactive routing protocols for Mobile Ad hoc networks also compare the performance of each one.
