An Experimental Architecture for providing QoS guarantees in Mobile Networks using RSVP

Efforts are underway to enhance the Internet with Quality of Service(QoS) capabilities for transporting real-time data. The ReSerVation Protocol(RSVP) provides a signaling mechanism for end-to-end QoS negotiation. The issue of wireless networks and mobile hosts being able to support applications that require QoS has become very significant. Reservation of resources and the maintenance of QoS for the mobile as it moves from one region to another creates a new set of challenges. In our paper, we describe an architecture where a modified RSVP protocol helps provide QoS support for mobile hosts. The modified RSVP protocol will be implemented in an experimental wireless and mobile testbed to study the effects of mobility on QoS, and the feasibility and performance of our approach
