摘要：A Mobile Ad-hoc Network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Routing in MANET is a challenging task due to mobility of nodes, infrastructure-less and lack of central administration. The main classes of MANET Routing Protocols are Proactive, Reactive and Hybrid. This paper evaluates performance of OLSR (Proactive), AODV (Reactive) and GRP (Hybrid) routing protocols by considering IEEE 802.11 Wireless LAN Standard and 48 Mbps data rate. . Two simulations have been carried out for these protocols, One for IEEE-802.11a and other for IEEE-802.11g WLAN Standard for scenario with 80 nodes and similarly for 100 nodes. The network performance is evaluated using OPNET, based on the quantitative metrics Media Access Delay (sec), Retransmission Attempts (packets), Throughput (bits/sec), Data Dropped (Retry Threshold Exceeded (bits/sec)) by varying Physical Characteristics and Network Size. The results are given with graphical representation
