What are Cons of wireless network?
The cons of a wireless LAN (Local Area Network - the type of network you have in your home or business) are speed and security.
Speed - This is a con when comparing a wi-fi/wireless network to a wired one. Typical wired ethernet networks operate at 100Mbps whereas the typical wireless network operates at about half that, 54Mbps. Of course your internet connection is likely to be much, much slower than either of these speeds so this will only affect you when transfering files on your LAN, not with Internet browsing or downloading files from the Internet, etc.
Security - Out of the box, most wi-fi routers and access points have no security enabled. This makes it easy for you to connect but it also makes it easy for anyone within range to connect. More and more newer wireless equipment is now coming with installation software that will help you set up the proper security to keep outsiders off of your network.

UDP protocol.
-----------------------------------
Well my version of answer is:
In the case of IP and UDP, these are unreliable protocols that do not guarantee delivery, so they do not notify the source. TCP does guarantee delivery. However, the technique that is used is a timeout. If the source does not receive an acknowledgment to data within a given period of time, the source retransmits.
