    • Connectivity Issues for Ultraviolet UV-C Networks 

      Vavoulas, A.; Sandalidis, H. G.; Varoutas, D. (2011)
      This paper focuses on the connectivity issues of a non-line-of-sight (NLOS) optical wireless network operating in the ultraviolet UV-C spectral region. NLOS UV-C transmitters have a limited effective coverage and, hence, ...

    • Node Isolation Probability for Serial Ultraviolet UV-C Multi-hop Networks 

      Vavoulas, A.; Sandalidis, H. G.; Varoutas, D. (2011)
      Non-line-of-sight optical wireless transmission, operated in the unlicensed ultraviolet UV-C band, has been recently suggested as an alternative means of communication. However, due to limited coverage, relayed UV-C networks ...

    • Underwater Optical Wireless Networks: A k-Connectivity Analysis 

      Vavoulas, A.; Sandalidis, H. G.; Varoutas, D. (2014)
      In this paper, optical wireless has been addressed as a promising technology to provide high-bandwidth services for underwater communications. However, the significant attenuation degree due to high absorption and scattering ...

    • Weather Effects on FSO Network Connectivity 

      Vavoulas, A.; Sandalidis, H. G.; Varoutas, D. (2012)
      The use of relays is one of the most promising methods for mitigating impairments of the performance of free-space optical (FSO) systems and extending their limited transmission range. However, several factors contribute ...
