Handoff delay in cognitive radios — A concept paper on utilization of guard channels
2011
In today's world of communication, everything is going wireless. The licensed and unlicensed bands of the Radio Frequency (RF) spectrum play a key role in wireless communication. Considering the tremendous growth in wireless applications and devices, the RF spectrum can be thought of as a sacred resource as it is the vital component which makes wireless communication possible. In addition, RF spectrum is a limited resource which makes it even more important to utilize it efficiently. Cognitive Radio (CR) technology is considered a solution for the efficient usage of RF spectrum. Keeping the significance of RF spectrum in mind, this paper describes a concept of using the guard channels in the spectrum mobility process which will help in preventing the scarcity of spectrum usage. Further more it will mitigate the handoff delay resulting in high-speed service times.
