Joint optimal access point selection and channel assignment in wireless networks
(2007)
In wireless cellular networks or in other networks with single-hop communication, the fundamental access control problem pertains to access point (AP) selection and channel allocation for each user. For users in the coverage ...
The impact of space division multiplexing on resource allocation: A unified treatment of TDMA,OFDMA and CDMA
(2008)
Space division multiple access (SDMA) with an antenna array at the transmitter is a promising means for increasing system capacity and supporting rate-demanding services. However, the presence of an antenna array at the ...
Cross-layer design for power efficiency and QoS provisioning in multi-hop wireless networks
(2006)
In recent years, it has become common consensus that independent consideration of communication layers often turns out to be inadequate in terms of providing the desired quality of service (QoS) and power efficiency in ...
Cross-layer adaptive techniques for throughput enhancement in wireless OFDM-based networks
(2006)
Although independent consideration of layers simplifies wireless system design, it is inadequate since: 1) it does not consider the effect of co-channel user interference on higher layers; 2) it does not address the impact ...
Challenges in Demand Load Control for the Smart Grid
(2011)
The ground to address challenges in demand load control for the smart power grid is now more fertile than ever, due to advances in communication infrastructures and the creation of a two-way channel for real-time communication ...
Adaptive channel allocation in OFDM/SDMA wireless LANs with limited transceiver resources
(2004)
Smart antennas increase capacity of wireless systems by allowing channel reuse by several users in the same cell through space division multiple access (SDMA). Orthogonal Frequency Division Multiplexing (OFDM) creates ...
Fast neighbor positioning and medium access in wireless networks with directional antennas
(2013)
We study the problem of fast neighbor positioning and medium access in wireless networks with directional antennas. In this problem, the cross-layer dimension inherently comes into stage through the impact of PHY-layer ...
Client-server games and their equilibria in peer-to-peer networks
(2014)
In peer-to-peer networks, each peer acts simultaneously as client and server, by issuing and satisfying content requests respectively. In this work, we use concepts from non-cooperative game theory to model the interaction ...
Experimentation on end-to-end performance aware algorithms Cross Mark in the federated environment of the heterogeneous PlanetLab and NITOS testbeds
(2014)
The constantly increasing diversity of the infrastructure used to deliver Internet services to the end user has created a demand for experimental network facilities featuring heterogeneous resources. Therefore, federation ...
Dynamic resource allocation in CDMA systems with deterministic codes and multirate provisioning
(2006)
Next generation wireless CDMA systems will provide high and variable data rates by using multicode structures, controllable code spreading gains, and transmit power adaptation. We address the emerging resource allocation ...
