Abstract
As technology has changed over the years many applications have kept pace with the changes and huge improvements have been made, such as cell phones. The power grid however has not stayed current with what technology has to offer. Resolving the gap between the existing grid and the smart grid is an area of fervent research. Much of the success of the smart grid relies on new communication architecture to allow for smart metering, quality of service implementations, and distributed power generation.
In a way there is an opportunity not just to incrementally change the grid, but to architect it intelligently for current and future needs. In this paper we review three papers that investigate communication needs in the emerging smart grid. There are varying mechanisms suggested to meet requirements, however there is a common theme that a fast, reliable, distributed communication architecture is needed. Without a well thought out architecture the smart grid will be plagued with latency, security, and reliability issues. Index Terms

MART grid is different from traditional power grid, which is a system made of electrical generators, transformers, transmission, and distribution lines used to deliver electricity power to users, in that it also consists of complex networks of intelligent
electronic devices, wired and wireless sensors, smart meters [1], distributed generators, and dispersed loads that require cooperation and coordination. The first paper we review details the technologies integrated in power grid, to be specific, smart grid. Then the second paper proposes a heterogeneous communication paradigm based on the requirements of the smart grid network. As smart grid has not been developed until recent years, every aspects of this new power grid architecture have yet to be implemented. Even for those implemented,
