Performance Analysis of MAC802.11 and MAC802.16 for AODV Routing Protocol in MANET

A Wireless Adhoc Network is a group of wireless mobile nodes is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. In this paper mainly focused on MAC layer because this layer is most important for data communication to control the packet loss and error, we analyze MAC layer 802.16 and 802.11 networks using Ad hoc on-demand Distance Vector Routing Protocol under MANET by varying pause time and maximum speed. These simulations are carried out using the Network simulator version-2. From the results it is seen that end to end delay is less, PDF is more packet loss is minimum on varying maximum speed and pause time of 802.16 when compared with 802.11. hence 802.16 shows better performance as compared with 802.11.
