Detailed explanation-1: -The biggest drawback to using ad-hoc mode is the lack of security, which is why most new wireless devices do not support the use of ad-hoc networks.
Detailed explanation-2: -Ad hoc networks often suffer from poor wireless communication range issues, because antennas built into endpoints were not designed to be as powerful as purpose-built WAPs. Ad hoc networks also do not scale well.
Detailed explanation-3: -The QoS of ad hoc wireless networks depends not only on the available resource but also on the mobility rates of such resources. The three main constraints related to the quality of service are Bandwidth constraints, Dynamic topology of networks, Limited processing and storing capacity of mobile nodes.
Detailed explanation-4: -Answer: a Explanation: An ad-hoc wireless network is a decentralized kind of a wireless network. An access point is usually a central device and it would go against the rules of the ad-hoc network to use one. Hence it is not required.
