Abstract
IEEE 802.16e classifies packets into 5 different service classes, namely, UGS, rtPS, ertPS, nrtPS and BE. Bandwidth is allocated to SS based on the need of the service class. In this paper we propose a user based bandwidth allocation mechanism called Differentiated Bandwidth Allocation Mechanism (DBAM). WiMAX users shall be divided into 3 different priority levels as high-priority users, regular users and low-priority users. Bandwidth shall be allocated to the service flows of these service class based on the priority of the users. This method of bandwidth allocation provides a differentiated QoS to users for the same service class. Simulation results revel that when the number of Subscriber Stations (SS) is 10, high-priority and Regular users are able to transmit 25% more ertPS data compared to low-priority users and when the number of SS is 14, high-priority user transmits 30% more data compared to regular user.
