  • 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

    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 ...
