(
Springer International Publishing
, 2015 , Article)
Wireless sensor networks (WSNs) were envisaged to become the fabric of our environment and society. However, they are yet unable to surmount many operational challenges such as limited network lifetime, which strangle their ...
Interference-based optimal power-efficient access scheme for cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new optimization-based access strategy of multi-packet reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectrum. We devise an analytical model that ...
Large-scale cognitive cellular systems: Resource management overview
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article Review)
This article presents recent advancements in resource management for large-scale DSA systems. Although the problem of spectrum and power allocation is well addressed in the literature, the need for more efficient algorithms ...
