Performance Evaluation of WIMAX Using ns-2

The performance of quality of services for an IEEE 802.16 based WiMAX access network is analyzed. WiMAX is an emerging broadband wireless communication standard used as a mode of transmission and high speed internet access. WiMAX is a technology which provides more bandwidth, better QoS, better security, greater coverage and has low infrastructure cost. The quality of service related parameters i.e jitter, throughput etc. are evaluated in this study using ns-2 modeler. Problem Statements : 1/Speed of connectivity. 2/Sharing of bandwidth. 3/low bit rate over long distance. Objectives (at least five): 1/ Performance evaluation through simulation. 2/ Increasing the transmission range would improve the efficiency better for the heavy load. 3/ A new users can be added to the network without any complication which results in a less cost. 4/Analyze the performance of WIMAX & to see how the performance of the network is affected when the number of workstation connected to the WIMAX is increasing. 5/ Analyze the performance of the network based on the output of the simulator through the following parameters: delay, jitter, throughput and packet drop.
