摘要：Mobile Ad hoc NETwork (MANET) is a collection of mobile nodes that are arbitrarily located such that the interconnections between nodes are dynamically changing. In MANET, mobile nodes form a temporary network without using any kind of existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. Route should be discovered and maintained with a minimum of overhead and bandwidth consumption. A wide range of routing protocols for MANETs has been proposed by researchers to overcome the limitations of wired routing protocols. This paper evaluated performance of proactive routing protocol and reactive routing protocol in variable pause time and variable number of nodes. We have used Optimized Link State Routing (OLSR) protocol as proactive routing protocol and Location-Aided Routing Scheme 1 (LAR1) protocol as reactive routing protocol. We have used RWP (random waypoint) mobility model and performed simulations by using QualNet version 5.0 Simulator from Scalable Networks. Performance of OLSR and LAR1 is evaluated based on Average end to end delay, Packet delivery ratio, Throughput and Average Jitter.
