Abstract
Abstract: Host mobility is one of the new services that have been introduced in the booming of world wide deployment of Internet. Providing QoS to mobile hosts is a challenging area because of its mobility. The resource ReSerVation Protocol (RSVP) establishes and maintains a reservation state to ensure a given QoS level between the sender and receiver. However, RSVP is designed for fixed networks and thus inadequate in the mobile networking environment. In this paper, we propose a resource reservation protocol for mobile hosts. The proposed protocol extends the RSVP and introduces RSVP agents to manage reservations in local networks. The proposed protocol reduces packet delay, bandwidth overhead without giving additional load to the backbone network, and the number of RSVP messages to maintain reservation states. We examined the performance of the proposed protocol by simulation.
