In this paper, competition among multiple secondary users (SUs) for spectrum access is modeled as a simultaneous repeated auction. Upon participation in an auction, a SU is charged with an entry fee. However, participation does not ensure an access to the channel. This tradeoff leads it to decide either for or against entering the auction. We consider no cooperation among the SUs, and model this situation...
One of the most desirable features of next generation wireless networks is the ability to move seamlessly over different access networks regardless of the underlying infrastructure. Handovers between dissimilar networks may be facilitated by the use of an efficient vertical handover algorithm. This paper explores ongoing research on the development of vertical handover decision methods and their effectiveness...
The ever-increasing dependence on the Internet is challenged by several factors impeding the smooth transition to the nomadic and ubiquitous future communications. These hindering factors are primarily attributed to the top-down approach in designing computer networks that resulted in adopting a layered architecture for abstracting network functionalities as well as for engineering protocols; a methodology...
