Host mobility is a new service that has been introduced in worldwide deployment of the Internet. Providing QoS to mobile hosts is achallenging area because of its mobility. The resource reservationprotocol (RSVP) establishes and maintains a reservation state to ensurea given QoS level between the sender and receiver. However, RSVP isdesigned for fixed networks and thus inadequate in the mobile networkingenvironment. We propose a resource reservation protocol for mobilehosts. The proposed protocol extends RSVP and introduces RSVP agents tomanage reservations in local networks. The proposed protocol reducespacket delay, bandwidth overhead without giving additional load to thebackbone network, and the number of RSVP messages to maintainreservation states. We examined the performance of the proposed protocolby simulation
