Compounding humanitarian and political crises within and across countries have been met with shrinking public resources for coordination, recovery, and mitigation.This resource constrained humanitarian environment presents opportunities for multinational corporations to supplement budgets and actively participate in new markets through connecting w
In emergency situations, such as disaster area monitoring, deadlines for data collection are strict.The task time minimization problem concerning multi-UAV-assisted data collection in equi-jec 7 wireless sensor networks (WSNs), with different distribution characteristics, such as the geographical or importance of the information of the sensors, is
A new definition of a graph called Pure graph of a ring denote Pur(R) was presented , where the vertices of the graph represent the elements of R such that there is an click here edge between the two vertices ???? and ???? if and only if ????=???????? ???????? ????=????????, denoted by pur(R).In this work we studied some new properties of pur(R) fi
In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading.We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branch orthogonal space-time block coding, in comparison with the optimal power and rate adaptation policy
