Abstract
This project discusses home area networks in Smart Grid. A Home Area Network plays a very important role in communication among various devices in a home. There are multiple technologies that are in contention to be used to implement home area networks. This project analyses various communication protocols in Home Area Networks and their corressponding underlying standards in detail. The protocols and standards covered in this project are ZigBee, Z-Wave, IEEE 802.15.4 and IEEE 802.11. Only wireless protocols have been discussed and evaluated. Various security threats present in the protocols mentioned above along with the counter measures to most of the threats have been discussed as well. Some of the threats where the counter measures are inadequate have been identified as potential areas of research.
