Performance Evaluation of MU-MIMO WLANs Under the Impact of Traffic Dynamics
… shows that 802.11ac MU-MIMO has severely limited throughput under closed loop traffic. Furthermore, we find that with the AP's co-ordination the system performance shifts closer to the maximum achievable throughput which is not possible under a contention based access mechanism. Next we show that …

Geographic location and geographic prediction performance benefits for infrastructureless wireless networks
… in the area of IWNs has been on connectivity and throughput/energy/delay (T/E/D) tradeoffs, which are important and valuable metrics. When specific IWN routing protocols are developed, they are often difficult to characterize analytically. In this thesis we review some of the important results in …

Precoder Design for Cooperative Cognitive Radio Systems
… with an aim of achieving maximum possible throughput for the secondary system for two different scenarios: one with multiple secondary relay nodes with a single antenna at each of the source, relay and destination nodes of the secondary system, and the other with a single secondary relay …

The role of control information in wireless link scheduling
… of the wireless channels to achieve maximum throughput. These opportunistic policies require global knowledge of the current network state to schedule transmissions eciently; however, providing a controller with complete channel state information (CSI) requires signicant bandwidth. In this …

Optimising energy efficiency and spectral efficiency in multi-tier heterogeneous networks : performance and tradeoffs
… between the two conflicting objectives such as achievable throughput and minimising the power consumption in two-tier HetNets for the downlink transmission scheme. Finally, a multi-objective optimization problem is formulated that jointly maximizes the EE and SE in two-tier HetNets. In this …

Connectivity, throughput, and end-to-end latency in infrastructureless wireless Networks with beamforming-enabled devices
… network connectivity, we analyze the achievable network throughput and scalability of both fixed and variable rate beamforming-enabled power-limited networks operating in a bounded region. Our study of the scaling behavior of the network is concerned with three QoS metrics of central …

Wireless Physical Layer Security: Towards Practical Assumptions and Requirements
… show how the optimal transmission design and the achievable throughput vary with the amount of knowledge on the eavesdropper's channel. Apart from the assumption of perfect CSI, the analysis of physical layer security often ideally assumed the number of eavesdropper antennas to be known. We …

Design Space Exploration of Digital Circuits for Ultra-low Energy Dissipation
… energy dissipation requirements on a design are achievable by employing various optimization techniques. Voltage scaling is the most effective knob to reduce energy dissipation. For this reason ultra-low energy design usually translates into ultra-low voltage or subthreshold (sub-VT) domain …
