Signaling and QoS guarantees in mobile ad hoc networks

We propose an architecture for provisioning non-disrupted QoS guarantees in mobile ad hoc networks, and extend the scalable resource reservation protocol (SRRP) 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 request-to-reserve/object-to-reserve/clear-to-reserve (ROC) reservation mechanism, and ad-hoc MPLS. We introduce a scalable adaptable reservation architecture (SARA) as a common architecture for reservation in SRRP. SARA is a scheme for signaling, reservation and QoS adaptation in ad hoc mobile wireless networks and which can also be used in the Internet. Finally, we propose geographical subpath protection, geographical circumscribed protection, and geographical extension protection with shared virtual reservation for non-disrupted QoS guarantees in the presence of interference, high mobility, bursty traffic, and/or other faults, without wasting expensive radio resources unnecessarily.
