Wireless communications technologies play an irreplaceable role in emergency and disaster relief situations. It is generally acknowledged that the existing public safety (PS) wireless communications facilities frequently fall short of meeting users' needs in many critical situations. Emergency scenarios usually lead to exceptionally high traffic loads, and the lack of network capacity is one of the major limitations to overcome. In this context, this article first discusses about several… Expand
