Final answer:
The two conventional channel allocation schemes are Fixed Channel Allocation (FCA) and Dynamic Channel Allocation (DCA), with the combination called Hybrid Channel Allocation (HCA). FCA has fixed assignments to avoid interference, whereas DCA adapts to network conditions by assigning channels on demand. HCA combines the predictability of FCA with the flexibility of DCA.
Step-by-step explanation:
The two conventional channel allocation schemes used in networks and telecommunications are Fixed Channel Allocation (FCA) and Dynamic Channel Allocation (DCA). A combination of these is called Hybrid Channel Allocation (HCA).
In FCA, a channel is assigned to a cell in a network and cannot be used by neighboring cells to avoid interference, ensuring that only certain channels are available at any given time in a particular area. This is easy to implement but can be inefficient if the traffic is unevenly distributed, as some channels can be idle while others are overloaded.
DCA, on the other hand, allows channels to be allocated on demand based on the current network conditions. This method improves efficiency by dynamically assigning channels where they are needed, allowing for a better distribution of channel usage according to traffic.
HCA attempts to leverage the best of both FCA and DCA by using a static allocation as a base and dynamically distributing additional channels based on immediate demand. This provides a balance between the predictability and stability of FCA with the adaptability and efficiency of DCA.
