Mobile ad-hoc network is a network (MANET) of wireless mobile nodes (MNs) that communicate with each other without centralized control or established infrastructure. Routing protocols are divided into Proactive and Reactive. Proactive is a table?driven protocols. The proactive routing protocols use link- state routing algorithm which frequently flood the link information about its neighbors. Reactive or on-demand routing protocols create routes when they are needed by the source host and these routes are maintained while they are needed. This paper proposes a solution for performance enhancement of VoIP and HTTP in Ad-hoc WLANs. This paper compares the performance of OLSR and GRP over different IEEE standards on the basis of delay, load, media access delay and throughput, GRP total traffic sent and received OLSR neighborhood change and draws a conclusion based on performance of the network over different QoS parameters.
