Improving Quality of Experience by Adding Device Resource Reservation to Service Discovery Protocols

Current service discovery protocols (SDP) hardly provide information on the actual availability of resources in the network or a mechanism for (device) resource reservation. When the resources cannot serve all multiple client requests at the same time, conflicts happen, often involving heavy and frequent reconfiguration traffic. This paper presents a generic resource reservation scheme. Its properties are derived from common SDP operations. We built a prototype, measured the extra overhead such a reservation manager introduces and simulated the gain in network scalability. The main conclusion is that our solution improves the scalability and the sustainability of the service access significantly, and at a minor cost.
