Split- and Aggregated-Transmission Control Protocol (SA-TCP) for Smart Power Grid

摘要

This paper introduces our proposed Split- and Aggregated-TCP (SA-TCP) scheme's enhanced TCP performance in a smart metering infrastructure (SMI). The scheme is based on upgrading intermediate devices (e.g., regional collectors) to aggregate TCP connections. An SA-TCP aggregator collects data packets from smart meters in a certain region over separate TCP connections, then reliably aggregates them in one TCP connection to the management server of the utility. Our proposed scheme responds better to data traffic dynamics of smart meters and makes TCP congestion control effective.
