Hotspot Problem, Inadequate for Time Critical Applications, Stationary Sink which is impractical ofcourse, Limited Scaling

Hello Sander Ali Sir thanks

but sir u can tell me that which wireless standard is more usable for it?

Try Stable Election Protocols like DEEC and DDEEC but if you want to extend the lifetime of the network as well then EDEEC and TDEEC protocols are used. You can easily find the literature for these protocols on internet

Thanks sir @sanket tapadia
