The modernization of the current power grid has brought forward many requirements in order to make possible the vision of a smarter grid. This paper presents these challenges and the current achievements in order to aid in its transformation. It identifies developing applications within the power network; from centralized generation to distribution in terms of power electronics, power systems, and...
Dynamic spectrum access (DSA) is proposed to deal with the growing shortage of available leased spectrum for wireless communication. We investigate a subset of DSA referred to as Dynamic Spectrum Leasing (DSL). At its core, DSL allows spectrum lease holders and cognitive radios to cooperate in an effort to leverage spatial diversity to improve channel utilization for both parties. In this research,...
In this work, an Adaptive Channel Hopping (ACH) mechanism for sensor networks is proposed to avoid interference from other sources and narrow-band jamming. Under unfavorable channel conditions, ACH lets sensors switch to a new operating channel. ACH reduces the channel scanning and selection latency by ordering available channels using link quality indicator measurements and weights. The proposed...
