| description | This paper reviews quorum systems (QS) from
the perspective of cognitive radio networks. Quorum systems
were originally developed for and widely used in the scope
of operating systems. Recently, quorum systems have been also
started to be applied to wireless communications. The objective
of this paper is threefold. First, the paper provides survey and
guidance on the use of quorum systems. Second,
it shows that QS properties provide an interesting alternative
towards an asynchronous communication in cognitive radio ad
hoc networks (CRANs). Due to properties of quorum systems it is
possible to establish CRANs without employing a common control
channel (CCC), perfect synchronization, or central controller
architecture. QS properties can be efficiently utilized to handle
the rendezvous (RDV) problem in CRANs. New RDV protocols
must be designed in such a way that there is a guarantee that
all nodes meet periodically within reasonable periods of time.
Since pseudorandom solutions do not provide this guarantee,
systematic approaches are needed such as QSs. Third, we also
propose a novel distributed RDV protocol, MtQS-DSrdv, which
is based on mirror torus QS and difference set concepts. The
proposed protocol guarantees RDVs on all available channels
while CR nodes have the same channel set. |
