AB  - A major proliferating architecture, that extends its services globally in wireless networks, is Ad Hoc network, which endows more research areas to work with. In next generation networks, user can be accurately determined and maintained by the network on per-user basis. This study investigates the design of Ad Hoc network architecture that exploits user profiles to maximize network efficiency and promote better quality of service by differentiated bandwidth reservation and resource allocation to different classes of users. A model called High-Privileged and Low-Privileged Architecture (HPLP) for the forthcoming Ad Hoc network is proposed through which differentiated services can be achieved for different class of users. A new MAC protocol named as D-MACAW is also suggested for the proposed architecture. Among the various factors influencing the differentiated services, bandwidth reservation is only considered and different factors that can influence the efficiency of the bandwidth reservation are identified. Two classes of users are considered as high-privileged, a high-cost and efficient service users and low-privileged, low-cost and best effort service users. The differentiated service provided for the different classes of users is proved through simulation analysis. The results obtained using ns2 show that efficient quality of service is guaranteed to users who subscribe high-privileged profile.
