Questions related to Network technology
LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices. And with claims such as that it is 100 times faster than the existing WiFi technology in terms of internet connectivity. Surely this is THE TECHNOLOGY OF CHOICE IN THIS ERA OF BIG DATA, CLOUD COMPUTING, THE INTERNET OF THINGS.
Low Power Wide Area Network (LPWAN) is communication technology providing connectivity for the IoT. The LPWAN technologies reside between the existing cellular mobile network technologies and the short-range technologies, providing a cost and energy efficient connectivity solution for such devices as smart meters, infrastructure and environmental sensors, or tracking devices. The LoRaWAN technology combines the proprietary LoRa modulation developed by Semtech company, and an open-source media access (MAC) and network level (NWK) standard developed by the LoRa Aliiance. One of the key features of this technology is the use of chirpspread-spectrum modulation technique with variable spreading factor (SF), appended on top of the linearly changing carrier frequency.

CAC is one of the proposed algorithm in ATM that accept new call and communicate with the bandwidth allocator to allocate a peak bandwidth then it chooses a routing strategy from three types:DLCP and SP and DNSP algorithms for the call data to be either accepted or rejected , now Hoc can it choose one of these routing ??based on what? and can the rejected data be return back again and the CAC choose another routing to be accepted??
Importing a network or graph is very common which can be visualized and analyzed using various software like Gephi etc but to design a family of networks or graphs that have say a desired set of network properties e.g. 5-8 links per node with node density dependent on space variables or something like that? If it is also done, please mention some reference or web-links. Thanks in advance!
