Comparative Analysis of FH and CFH Spread Spectrum Under Different Jammers

The wireless nodes often share the information through communication channel with other wireless technologies. Since the transmission medium is an open medium, nodes must transmit the information in a secured manner and to achieve better transmission rates in the presence of static and dynamic interference. The FHSS technique plays a major role to mitigate interference. In FHSS, if the current hop is corrupted by the interference, the node can send the data successfully when it switch to another new channel. But, when number of channels corrupted by interference are more, then the performance of FHSS gets degraded. So to overcome this issue a Chaotic Frequency Hopping (CFH) technique is used. The CFH selects the hopping channel based on the chaotic map. The CFH technique increases security in the presence of static and dynamic interference. In this paper, we performed a comparative analysis of FHSS and CFHSS in presence of different jammers.
