In this paper, we propose DIME (DIffServ MAC Extension), an extension of the IEEE 802.11 MAC protocol to support Differentiated Services. The proposed extension consists of two optional modules: the Expedited Forwarding (EF) and the Assured Forwarding (AF). The Expedited Forwarding extension (DIMEEF) reuses the Interframe space of the Point Coordination Function (PCF) of the IEEE 802.11 standar...

In this paper we present a new mechanism to provide an assured service in terms of target rate and fair excess bandwidth, like the Internet Assured Service. Research in Internet Assured Service faced up both questions in separate ways proposing different traffic conditioners to work with the RIO buffer management, and proposing different modifications to this buffer management, among others. In...

This is a case report of the effective use of bi-level positive airway pressure support (BPAP) using the volume-assured pressure support feature in a pediatric patient with a congenital myopathy and significant nocturnal hypoventilation. Our patient was started on nocturnal nasal mask BPAP but required high pressures to improve her oxygen saturations and CO2 baseline. She was then trialed on a ...

Current and upcoming avionics systems must be able to accommodate expected growing application software volume and capability. The software domain has struggled to meet increasing demands while retaining the necessary level of confidence in its appropriate operation. Meanwhile, although computing components are becoming less expensive, the fixed and operational costs of hardening them to their ...

Many users require IP networks with the capacity to guarantee a minimum throughput even during periods of congestion. Furthermore, it is also desirable to share the excess unsubscribed bandwidth among active users if aggregate demand does not exceed network capacity. This kind of service, named assured service, can be provided through the Assured Forwarding (AF) Per Hop Behavior (PHB) defined i...

The theory of assured fitness returns proposes that individuals nesting in groups gain fitness benefits from effort expended in brood-rearing, even if they die before the young that they have raised reach independence. These benefits, however, require that surviving nest-mates take up the task of rearing these young. It has been suggested that assured fitness returns could have favoured group n...

Presented cloud computing billing model is designed for maximizing value-adding throughput of a multiuser parallel computing platform across a set of users of the platform. The model enables maximally demand driven computing capacity allocation while guaranteeing each user application its contract-based assured minimum capacity access level whenever actually demanded. The billing model thus fac...
