  • Planar unclustered graphs to model technological and biological networks 

    Miralles de la Asunción, Alicia; Chen, Lichao; Zhang, Zhongzhi; Comellas Padró, Francesc de Paula (2009-02-25)
    Article
    Open Access
    Many real life networks present an average path length logarithmic with the number of nodes and a degree distribution which follows a power law. Often these networks have also a modular and self-similar structure and, in ...

  • Self-similar non-clustered planar graphs as models for complex networks 

    Comellas Padró, Francesc de Paula; Zhang, Zhongzhi; Chen, Lichao (2008-10-10)
    Article
    Open Access
    In this paper we introduce a family of planar, modular and self-similar graphs which have small-world and scale-free properties. The main parameters of this family are comparable to those of networks associated with complex ...
  • Token-MAC : a fair MAC protocol for passive RFID systems 

    Chen, Lichao; Seyfettin Demirkol, Ilker; Heinzelman, W. (IEEE, 2011)
    Conference report
    Restricted access - publisher's policy
    Passive RFID systems typically utilize contention-based MAC protocols, such as the standard C1G2 protocol. While these protocols are easy to implement, they suffer from unfairness and low throughput. This paper proposes a ...
