1.	Which among the following is not a disadvantage ICMP protocol for direct inter layer communication?(a) IP headers are included(b) High protocol processing overhead(c) Limited to request-respond action(d) Loss of message packet cannot be identifiedThis question was addressed to me by my college director while I was bunking the class.Query is from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio
Answer» The CORRECT choice is (d) Loss of message packet cannot be identified For explanation I would say: ICMP protocol has a large protocol header and protocol processing overhead. It is limited to request-response actions. However, cross-layer DESIGN demands for ASYNCHRONOUS COMMUNICATION. This can be overcome by creating a call BACK function with a procedure suited to the needs of the layers under consideration.
