• Update Ph.D. Courses Section
• CVs Update

[06/07/2010]

• Our paper "A Bargaining Approach to Power Control in Networks of Autonomous Wireless Entities" was accepted as a regular paper in the ACM MobiWAC Symposium   

• We submit a paper that combines power control and bargaining to find feasible solutions in cases where the classic power control algorithm fails  
• Here are the results of my evaluation as TA in Algorithms

• Update Teaching Assistant and Ph.D. Courses Sections
• CVs Update

[24/10/2009]

• Added material from my participation in the Future Internet Summer School 2009 (FISS 09). See Sections Publications and Personal.

[18/10/2009]

• Site was redesigned from scratch :-)
• CVs update
• Update Teaching Assistant Section

• CVs update
• A survey paper on Power Control in Cellular Networks is on the way to be submitted in a journal/ magazine
• I gave a related talk on "Power Control in Wireless Networks: Challenges, Solutions and Some Open Issues". Enjoy! ;-)
• I am going to attend a summer school in Bremen in a couple of weeks... busy period!

• A topic for M.Sc. Thesis (which may suitably downgrade to a B.Sc. Thesis for advanced undergraduate students) is now available. Title: "Uniform Performance Evaluation of Power Control Algorithms in Wireless Networks through Simulation". A small description can be found here. Some initial references are also available.

  Some preliminary comments:
  This thesis is expected in its final form someday during 201Y, WHERE 2<=Y<=? (an upper theoretical bound for '?' may be 9!!!) ;-)
  I will do my best to update all this stuff but you have to be a bit patient!...
  How long? Answer: Just (201Y-2008) years! :-)... Please, remember that I am always keeping my (important) promises! :-)

  Motivation - Abstract:
  Our motivation is based on the following scenario: If some friends stay in the same neighborhood, each one being owner of one Access Point -AP and they all transmit at the same frequency, could the adoption of power control algorithms be capable of distribute their incomes in a fair way?... more
