This paper investigates the adaptive local resource reservation call admission control protocols. The algorithms are built upon the concept of guard channel and we use an adaptive algorithm to track the optimal number of guard channel resources to reserve at a base station. We compare the following adaptive algorithms, one based on the Wiener prediction theory and the other based on the arrival...

In this paper, a rate-based admission control scheme for a single shared wireless base station with opportunistic scheduling and adaptive modulation and coding (AMC) is proposed. The proposed admission scheme maintains minimum average rates of the admitted users, i.e., new users will be admitted if the base station has enough resources to support the requiredminimum average transmission rates o...

QoS guarantees for an integrated CDMA system can be provided by a combination of admission and flow control. The admission control restricts the number of users in the system such that QoS requirements for all calls can be met. The flow control balances the system interference on a slot by slot basis such that Bit Error Rate requirements are met for all users and the real time users are given t...

The history of telephone networks indicates a trend of employing sophisticated switches and dumb hosts. Hence, it is often expensive and difficult to replace switches and add new applications. In contrast, Internet employs simple routers and sophisticated applications in hosts. New applications can be added without requiring infrastructural changes. In order to keep routers simple, there is a g...

In our earlier work, we have presented a simple measurement-based admission control (MBAC) scheme for modified Bandwidth Broker framework. In that scheme, real time (RT) traffic is basically able to starve non-admission controlled non-real time (NRT) traffic. By concentrating on real time application requirements it may be hard or even impossible to use other objectives in admission decisions; ...

Large-scale datacenters (DCs) host tens of thousands of diverse applications each day. Apart from determining where to schedule workloads, the cluster manager should also decide when to constrain application admission to prevent system oversubscription. At the same time datacenter users care not only for fast execution time but for low waiting time (fast scheduling) as well. Recent work has add...

Universal mobile telecommunications system (UMTS) is one of the 3 generation (3G) cell phone technologies. The capacity of UMTS is interference limited. Radio resources management (RRM) functions are therefore used. They are responsible for supplying optimum coverage, ensuring efficient use of physical resources, and providing the maximum planned capacity. This paper deals with admission contro...

In this paper we study measurement{based admission control for buuerless multi-plexing, which is very attractive for real{time traac. We rst discuss a novel Large Deviations (LD) approach to measurement{based admission control. We then provide an extensive review of the existing literature on measurement{based admission control. We conduct simulation studies with traces of MPEG 1 encoded movies...
