Modern networks provide QoS model to go beyond best-effort services, but current QoS models are oriented towards low level network parameters (e.g. bandwidth, latency, jitter) application developers on the other hand are interested in quality models that are meaningful to the end-user and therefore struggle to bridge the gap between networks and application QoS models. Network-aware applications are...
This paper studies the problem of adaptive resource allocation for downlink transmission at the base station (BS) of future multi-service IP-based networks. A delay margin based scheduling (DMS) approach is proposed to determine the queuing priority of an incoming packet by taking into consideration the distance between its currently experienced delay and its maximum allowed limit since such an instantaneous...
Resource reservation in mobile environments is an important task in the future when the userpsilas point of attachment to the network changes frequently due to mobility. One crucial issue of this task is to release unnecessary reservation along old path after departure of mobile node(s). Although this can be done automatically by a soft state mechanism, default soft statepsilas lifetime which is conceived...
Guarantees on quality-of-service (QoS) are essential for multimedia applications such as wireless TV and VoIP (voice over IP) to be successfully utilized over a WMN (Wireless Mesh Networks). As a consequence of providing Internet access to many clients over such a network, throughput is affected by the number of hops that a client is from its backhaul and how traffic load distributing. These spatial...
