In this article, the authors outline some key benefits that stem from the use of mechanical relaying within or across the cells in future wireless mobile networks. The authors have argued that, when information messages that can be stored are elastic enough and subsequently carried by mobile nodes, before relayed to other terminals or the BS at a later time, interference and energy consumption lev...

The decentralization of wireless networks to reduce the dependence on fixed infrastructures such as base stations has become the subject of vast interest in the past few years. In the future, this might form the backbone of general commercial mobile networks too. Such a system would be quite attractive for network operators and users alike, as it is inherently better suited to respond robustly to ... View full abstract»

The exponentially increasing demand for wireless data services requires a massive network densification that is neither economically nor ecologically viable with the current cellular system architectures. A promising solution to this problem is the concept of small-cell networks (SCNs), which is founded by the idea of a very dense deployment of self-organizing, low-cost, low-power, base stations (...

Recently, considerable attention has been devoted to the potential cognitive femtocell to allow for higher capacity and intelligent coverage, with guaranteed quality of service (QoS) for future indoor services. This interest is because of the fact that femtocells can access a resource, sufficiently and locally, to known users with higher throughput. In this article, cognitive femtocell is proposed...

In this article, a basic scheme and numerous variants on the use of SSCs were presented. Typical scorecard content, including critical user and device identification categories, was also provided. In presenting the basic architecture for the scorecards, key infrastructure elements were introduced: 1) an SC-I that provides a signature, timestamp, and queries assertion information providers; 2) an S...

In this article, a network-level, service-usage solution, which provides assured accounting information strongly bound to the host identity, so that the user is unable to repudiate the charges. To protect the user, the solution employs a granular approach, where evidence of service usage is provided in a piecemeal manner, i.e., pay as you go. An implementation of such a solution is presented, whic... View full abstract»
