A flexible receiver-driven cache replacement scheme for continuous media objects in best-effort networks

A cache-based mobility-aware scheme for real-time continuous media delivery in wireless networks

“…GD-multi employs a multi-parametric cost function to compute the utility of caching CM objects as many factors affect the quality of CM delivery on a network. Without loss of generality, quality of CM delivery can be measured largely in terms of the following factorspacket loss, delay and jitter [3]. The degree of influence that these factors have on CM delivery largely depends on the nature of each application.…”

“…The aim of service migration is to enable mobile clients to be serviced by information sources closer to their new point of connection, thereby, i) improving or at least maintaining QoS at the mobile clients and ii) reducing unnecessary network resources. To assess the utility of service migration, we perform comparative simulation studies of scenarios with a set of Greedy Dual-multi (GD-multi) [3] caching proxies servicing a network of mobile last hop clients. The layout of this paper is as follows:…”
