Performance evaluation of a rpl hybrid objective function for the smart grid network

Abstract

Multiple heterogeneous communication technologies offer great opportunities in Smart grid network by using wire, wireless and optic fiber. Most of future smart meters will use Powerline Communication (PLC) technology in addition to one or more wireless interfaces to tackle the physical constraints and failure of the PLC network. When a smart meter is connected using two different technologies, choosing the best relay node and the best link to transmit the message is a key decision to provide a good quality of service and increase the reliability of the communication network. In this paper, we propose an algorithm to manage multiple interfaces at the routing level (using RPL), and a re-transmission scheme to improve the reliability of the network when a PLC interface fails.
