Data re-sequencing delays in smart grids

Currently, legacy electrical power grids are being modernized into Smart Grids (SG). These will in turn play a crucial role in real-time balancing between energy productions versus energy consumption. Each SG will dedicate an advanced metering infrastructure that facilitates collection, storing as well as analyzing data from smart meters to the authorized parties, and also carrying commands, requests, messages and software updates from the authorized parties to the smart meters. As such, data aggregation as well as unimpeded data relaying is a prerequisite for guaranteeing a large acceptance and deployment of SGs. In this paper we provide an overview framework for analyzing packet re-sequencing within the SG. We utilize the random shortest path calculation algorithm to select the desired routes from source to a given destination. It is from among these that ultimately multipath (dual path) routing of the AMI data is carried out, hence resulting in re-sequencing necessities.
