**2.1 Differentiated Bandwidth Allocation Mechanism (DBAM)**

There shall be three different categories of users/MS as listed in Table 1.


Table 1. Classification of Users into three different categories.

Fig. 2. DBAM Algorithm.

From the algorithm in fig.2, we see that when the BS receives bandwidth requests for BE traffic from High-Prioirty, Regular and Low-Priority users, BS shall allocate bandwidth first to the high-priority user then the regular user and finally to the low-priority user (Kumar et al. 2011a).
