Abstract: In technological world smart grid helps in two way communication along with the transmission of the electricity on the same transmission line which strives to improve performance, security, reliabilities and lifetime of the heterogeneous network when deployed in building or industries. In this paper we discuss about architecture of smart grid, Technologies and standard protocols adopted which support the interoperability in smart grid and influence of heterogeneous infrastructure on improvising the latency, number of hops and life time.

Keywords: Smart Grid, Power Grid, Network Performance, Lifetime, Mesh Network, Latency.
