Interference management using one bit feedback

This paper studies the performance of quasi-static spectrum sharing networks utilizing one bit interference indicator feedback. Assuming no channel state information at the transmitters, the channel average rate is obtained under different power allocation strategies. Simulation results show that interference indicator feedback leads to considerable rate increment even with no transmitter channel state information

Improved Animal Tracking Algorithm using Distributed Kalman Filter-based Algortihms

Animal tracking has been addressed by different initiatives over the last two decades. Most of them rely on satellite connectivity on every single node and lack of energy-saving strategies. This paper presents several new contributions on the tracking of dynamic heterogeneous asynchronous networks (primary nodes with GPS and secondary nodes with a kinetic generator) motivated by the animal tracking paradigm with random transmissions. A simple approach based on connectivity and coverage intersection is compared with more sophisticated algorithms based on ad-hoc implementations of distributed Kalman-based filters that integrate measurement information using Consensus principles in order to provide enhanced accuracy. Several simulations varying the coverage range, the random behavior of the kinetic generator (modeled as a Poisson Process) and the periodic activation of GPS are included. In addition, this study is enhanced with HW developments and implementations on commercial off-the-shelf equipment which show the feasibility for performing these proposals on real hardware

Smart Grid Traffic Modeling in GSM and LTE using Multidimensional Markovian Process

The traditional electrical grid has provided electricity over a decades. Since then it has been of static nature without significant update and offers limited control. But as of now with rise in demand of power the traditional grid is not capable of meeting them. Also, several blackouts have occurred which raises the serious Questions on grid reliability and efficiency. Recently smarter solution has been suggested to address the above problem. It will take the advantage of advanced Information and Communication technology (ICT) and transform the grid into Smart grid
