Call admission control is a key element for providing quality of service (QoS) in mobile wireless networks. Traditional admission control schemes only address call-level QoS guarantee because of the underlying circuit-based network architecture. In contrast, emerging wireless technologies such as 3G and 4G tend to be packet-switched rather than circuit-switched because the packet-based architec...

This paper describes the handover mechanism in the standard 802.16e, which has implemented three handover methods  Hard Handover (HHO), Fast Base Station Switching (FBSS) and Macro Diversity Handover (MDHO) at this moment. Moreover, the handoff scheme is presented based on fuzzy logic. The mechanism takes under consideration three criteria: geographical data, received power level and used band...

Tracking the target that maneuvers at a variable turn rate is a challenging problem. The traditional solution for this problem is the use of the switching multiple models technique, which includes several dynamic models with different turn rates for matching the motion mode of the target at each point in time. However, the actual motion mode of a target at any time may be different from all of ...

In the first part of the paper, daily price data for the past three summer seasons in the PJM wholesale market are used to estimate a stochastic regime switching model. These data show that the average price in 1999, when market-based offers were allowed, was twice as high as it was in the previous two seasons when offers had to be cost-based. The primary cause was that the price spikes in 1999...

This paper is a tutorial review of some former and recent work in classification of switching functions. Considered are different approaches to the classification and discussed features of resulting classification methods.

Two tournaments T1 and T2 on the same vertex set X are said to be switching equivalent if X has a subset Y such that T2 arises from T1 by switching all arcs between Y and its complement X \ Y . The main result of this paper is a characterisation of the abstract finite groups which are full automorphism groups of switching classes of tournaments: they are those whose Sylow 2-subgroups are cyclic...

Hypermarkets play an increasingly important role in the retail industry in Taiwan. In this study hypermarket customers in Taiwan were surveyed, using switching costs as a variable, to explore the relationship between customer value, customer satisfaction, and customer loyalty. The results indicate that a customer with a more positive perception of the value of products/services has a more posit...
