Abstract The Third Generation Partnership Project's Long Term Evolution-Advanced is
considering relaying for cost-effective throughput enhancement and coverage extension …

Shrinking cell sizes, primarily a result of kee** up with the increasing demand for higher
data rates, are stretching thin the notion of our traditional cellular system architecture. More …

Data communication over power line networks has a number of similarities with
communication using wireless transmission. This (probably) goes back to fact that neither …

The increasing demand for wireless services has led to a severe energy consumption
problem with the rising of greenhouse gas emission. While the renewable energy can …

Optimizing vehicular communication strategies is important for an efficient usage of the
available wireless bandwidth and also critical for the success of VANETs. In this paper we …

In this paper, we propose a new concept called mobile Femtocell (MFemtocell) network,
which can be considered as a practical implementation of mobile relays (more precisely …
