CTN Issue: April 2012
However, this level of Context Awareness can not be achieved with the current state of context sources. These sources (smartphones, sensor networks, online Web services, etc.) are fragmented and do not comply with any standard. An application wanting to retrieve the complete context picture of a user will need to specifically poll all of them, using different interfaces and formats, to retrieve the required data. This is not efficient by any means. IEEE Communications MagazineEvolution of the Standards for Packet Network Synchronization
CTN Issue: March 2012
The evolution of telecom networks away from the traditional circuit switched structures towards the evolving next generation network with packet switching has changed the model from one of a carefully planned and engineered network towards one in which there is a greater expectation of automatic, self-configured operation a plug and play model. IEEE Communications MagazineA General Framework for Performance Analysis of Space Shift Keying (SSK) Modulation in the Presence of Gaussian Imperfect Estimations
CTN Issue: March 2012
Spatial Modulation (SM) is a promising multiple-input-multiple-output (MIMO) transmission technique that utilizes the spatial information in a novel fashion. At each time instance, only a single transmit antenna is activated among the set of existing transmit antennas to transmit either a fixed power (no constellation symbol), as in Space Shift Keying (SSK), or a constellation data symbol from the activated transmit antenna, as in conventional SM. IEEE Communications LettersSpectrum Monitoring during Reception in Dynamic Spectrum Access Cognitive Radio Networks
CTN Issue: March 2012
If a frequency band has primary and secondary users, then the cognitive radios of the secondary users must monitor the band and cease to transmit if a primary user's radio begins to transmit. Traditional methods require the secondary users to not transmit while they monitor for the emergence of primary user signals. This article proposes and analyzes techniques by which the secondary radios can continue transmitting during monitoring. IEEE Transactions on CommunicationsA survey on facilities for experimental internet of things research
CTN Issue: February 2012
The proliferation of an enlarged gamut of devices able to be directly connected to the Internet is leading to a new ubiquitous-computing paradigm. Indeed, the Internet has experienced a tremendous growth in the past three decades, evolving from a network of a few hundred hosts to a platform capable linking billions of “things” globally, including individual people as well as enterprises of various sizes, through computers and computerized devices of any conceivable size and capability and the applications running on them.
