created standards that they would later number 802.x, where x was the subcommittee developing the particular standard (Pidgeon, 2001b). The subcommittee that developed the standards for the CSMA/CD, functionally very similar to the DIX Ethernet system, was 802.3. Later in 1985, the official standards were released for the IEEE 802.3.

A Survey on Internet of Things: Security and Privacy Issues

from a PHY perspective, the current IEEE 802.15.4-2006 PHY layer(s) suffice in terms of energy efficiency. Given that a large amount of IoT applications however will require only a few bits to be send. It may be advisable to commence looking into a …
