Energy-Efficient Resource Allocation in Wireless Networks with Quality-of-Service Constraints
Energy efficiency delay quality of service game theory Nash equilibrium power and rate control admission control cross-layer design
2015/9/29
A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks. In the proposed game, each us...
Compressed Neighbor Discovery for Wireless Networks
Compressed Neighbor Discover Wireless Networks
2011/3/2
This paper studies the problem of neighbor discovery in wireless networks, namely, each node wishes to discovery and identify the network interface address (NIA) of those nodes within a single hop.
Hybrid FEC/ARQ performance and audio quality over wireless links
Hybrid FEC/ ARQ Markov Model audio quality
2010/9/25
Real time flows transmission over wireless networks often suffers from packet loss, delay and jitter. The main problem to implement a wireless network is the high and variable bit error rate in the ra...
Energy and Utility Optimization in Wireless Networks with Random Access
Wireless Networks Random Access
2010/11/24
Energy consumption is a main issue of concern in wireless networks. Energy minimization increases the time that networks’ nodes work properly without recharging or substituting batteries. Another crit...
Sensor Selection for Event Detection in Wireless Sensor Networks
Sensor Selection Wireless Sensor Networks
2010/11/24
We consider the problem of sensor selection for event detection in wireless sensor networks (WSNs). We want to choose a subset of p out of n sensors that yields the best detection performance. As the ...
We study a wireless broadcast network, where a single source reliably communicates independent messages to multiple destinations, with the aid of relays and cooperation between destinations. The wire...
Asymptotic Spectral Efficiency of Multi-antenna Links in Wireless Networks with Limited Tx CSI
Asymptotic Spectral Efficiency Multi-antenna Links Wireless Networks
2010/12/9
An asymptotic technique is presented for finding the spectral efficiency of multi-antenna links in wireless networks where transmitters have Channel-State-Information (CSI) corresponding to their targ...
Two-Way Transmission Capacity of Wireless Ad-hoc Networks
Two-Way Transmission Capacity Wireless Ad-hoc Networks
2010/12/1
The transmission capacity of an ad-hoc network is the maximum density of active transmitters per unit area, given an outage constraint at each receiver for a fixed rate of transmission. Most prior wor...
