Performance Analysis of IEEE 802.11 and IEEE 802.11 Ext. Mac Protocols in MANET

The wireless communication is advancement in sensor network which motivates the wireless sensor networking. Network technologies are traditionally based on wireline solutions. But the introduction of the IEEE 802.11 standards have made a huge impact on the market such that laptops, PCs, printers, cellphones, and VoIP phones, in our homes, in our offices and also in public areas have incorporated the wireless LAN technology. Wireless broadband technologies nowadays provide unlimited broadband access to users which were previously offered only to connection oriented users. In this thesis IEEE 802.11, which is a set of physical layer standard for implementing wireless local area network computer communication in the 2.4,3.6,5 and 60GHz frequency band is compared with IEEE 801.11 extension by taking various parameters like throughput, packet delivery ratio and packet drop ratio etc. the simulation is done using NS2 simulator by taking 20,40 and 80 nodes for both IEEE 802.11 as well as IEEE 802.11 extension.
