Signaling and QoS guarantees in mobile ad hoc networks

In this paper, we propose an architecture for provisioning nondisrupted QoS guarantees in mobile ad hoc networks, and extend the scalable resource reservation protocol (SRPP) for signaling in ad hoc networks. In particular, we present a number of techniques that can enable QoS guarantees In ad hoc networks, including geographical reservation and clusterhead election (GRACE), the quest-to-reserve/object-to-reserse/clear-to-reserve (ROC) reservation mechanism, and ad-hoc MPLS. We introduce a scheme for signaling, reservation, and QoS adaptation in ad hoc mobile wireless networks and the Internet. Finally, we propose geographical sub-path protection, geographical circumscribed protection, and geographical extension protection with shared virtual reservation for nondisrupted QoS guarantees In the presence of interference, high mobility, bursty traffic, and/or other faults, without wasting expensive radio resources unnecessarily.
