The paper cogitates about a comparative simulation for various distillation, reconciliation, and privacy amplification techniques that are used to generate secure symmetric physical layer keys. Elementary wireless model ...
A cooperative Q-learning approach for distributed resource allocation in multi-user femtocell networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
This paper studies distributed interference management for femtocells that share the same frequency band with macrocells. We propose a multi-agent learning technique based on distributed Q-learning, called subcarrier-based ...
On spectrum sharing between energy harvesting cognitive radio users and primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Delay minimization through joint routing and resource allocation in cognitive radio-based mesh networks
(
IEEE
, 2012 , Conference Paper)
We consider wireless mesh networks in which the nodes are utilizing cognitive radios and try to opportunistically gain access to spectrum resources. In such networks, the timely delivery of the traffic is a challenging ...
Optimum power and rate allocation in cluster based video sensor networks
