This paper proposes a concept for a new technical field called wireless distributed network (WDN) as a strategic technical field to enable flexible networking and radio resource management (RRM) to cope with dynamic variation of spatially distributed traffic demands. As the core technical subject areas for the WDN, this paper identifies distributed networking for flexible network creation, coop...

The performance of a mobile network is essentially based on the capacity of its radio access technology. A mobile network is spatially and functionally distributed. Its subsystems are in constant interaction with each other and with their geographic environment. Finding an appropriate approach to evaluate the capacity of a radio access technology with respect to a wide range of parameters (radi...

Introduction: The General Packet Radio Service (GPRS) is a packetoriented extension to the Global System for Mobile Communications (GSM) that supplies higher data rates and sharing of radio resources. The performance of the Internet protocols in GPRS is dependent not only on the quality of the radio link, but also on buffering in the GPRS network. According to [1–3], the over-sized network buff...

In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology. ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximat...

A wireless sensor network that employs passive radio wake-up of the sensor nodes can reduce the energy cost for unnecessary idle listening and communication overhead, extending the network lifetime. A passive wake-up radio is powered by the electromagnetic waves transmitted by a wake-up transmitter rather than a battery on the sensor node. However, this method of powering the wake-up radio resu...

Software Defined Radio (SDR) and Cognitive Radio (CR) are the key enabling technologies to overcome the spectrum scarcity problem a bit, by supporting dynamic spectrum access in which either a network or a wireless node reconfigures its transmission or reception parameters to communicate efficiently, avoiding interference with licensed or unlicensed users. CR senses the environment and enables ...
