Performance Evaluation of BWR Mechanism in MAC 802.16 for WI MAX in Pervasive Computing Environment Using NS-2

Performance evaluation of BWR mechanism in MAC 802.16 for WiMAX in a pervasive computing environment using NS-2 project, aims to analyze the BWR scheme in terms of the delay and throughput; then proposes evaluation to the same scheme. 

We analyze and obtain a formula for the delay incurred and throughput in BWR. In this project, we will analyze the reasons behind the delay in uplink and provide a new approach for dealing with this problem.

WiMAX is one of the widely used broadband services with IEEE standards which works on IEEE 802.16 MAC protocol. Users who use Wimax will request bandwidth through Subscriber station (SS)  to the base station which is called uplink bandwidth allocation.

In this process of bandwidth request (BWR) collision of packets is one of the problems which cause a delay in transmission time and reduce the efficiency of the wireless network.

In order to improve uplink transmission through output new mechanism is implemented called as circularity.
