Question

Which among the following is a disadvantage of the signaling pipe?

a.

Lack of instant signaling

b.

Separate headers for non-adjacent layers

c.

Unreliable delivery of information

d.

Generation of interface between non-adjacent layers

Posted under Cognitive Radio

Answer: (a).Lack of instant signaling Explanation:Interlayer signaling allows signaling information to pass from layer to layer along with packet flow. The processing path in the protocol stack may pass from top to bottom or from bottom to top. This is not suitable for cross-layer implementation since it requires instant signaling.
