Frequency rolling: a cooperative frequency hopping for mutually interfering wpans

A Wireless Personal Area Network (WPAN) provides wireless links among proximate devices, usually carried by an individual. As WPAN gains momentum in ubiquitous usage, the interference that collocated WPANs cause to each other, termed self-interference, becomes one of the major sources that degrade the communication performance of WPAN. This paper introduces the Frequency Rolling (FR), a particular instance of frequency hopping (FH) that enables the collocated WPANs to cooperate and avoid the self-interference. The FR uses as input solely the observed packet error rate (PER) and it does not require any exchange of information among the collocated WPANs. The effect of the FR over a longer time interval is that the WPANs use the complete set of disposable channels in an implicit time-division and cooperative manner. The parameters of the FR are chosen such that a WPAN which uses FR never occupies the channels in the unlicensed spectrum more than what is permitted by the current regulatio...
