ASAP Adaptive QoS Support with Reduced Reservation Overhead in MANETs
Patrick Stuedi, Xue, Jianbo, Alonso, Gustavo · Repository for Publications and Research Data (ETH Zurich) · 2004
Existing QoS approaches for mobile ad hoc networks focus on optimizing end-to-end bandwidth allocation with respect to, e.g., node mobility, link-failures and packet-loss. Typically this is achieved through over-reservation. This is specially true in loosely connected networks or in high mobility scenarios where reservations take place only on part of the path because no end-to-end connection is available. In this paper, we propose ASAP, an Adaptive ReServation and Pre-Allocation Protocol for mobile ad hoc networks. ASAP provides high service quality and minimizes wasted reservations. It does so by using a simple soft/hard reservation mechanism and a flexible signaling schema.
