The opening of the ultrahigh frequency (UHF) TV band by the Federal Communications Commission for opportunistic operation promises to relieve the demand on the industrial, scientific, and medical (ISM) bands. However, supporting bandwidth-intensive applications over TV white spaces can be quite challenging, due to the unpredictable nature of spectrum availability and the fluctuations in channel quality...
Rendezvous is a vital process for connection establishment and recovery in dynamic spectrum access (DSA) networks. Frequency hopping (FH) is an effective rendezvous method that does not rely on a predetermined control channel. Recently, quorum-based FH approaches have been proposed for enabling asynchronous rendezvous between two or more secondary users (SUs). In this paper, we consider two collocated...
Establishing communications in a dynamic spectrum access (DSA) network requires communicating nodes to “rendezvous” before transmitting their data packets. Frequency hopping (FH) provides an effective method for rendezvousing without relying on a predetermined control channel. FH rendezvous protocols have mainly targeted pairwise rendezvous, using fixed (non-adaptive) FH sequences and assuming a homogeneous...
