A routing algorithm is proposed to increase link
reliability in smart metering over low-tension power line grid.
The algorithm assumes data concentrator (DC) is polling meters
connected to the power line to send energy consumption, loading
profile and any other crucial data to the utility. The proposed
algorithm is designed to keep the needed complexity at the meters
at minimum, while moving the intelligence up to the DC. The
protocol accounts for asymmetric characteristics of the power
line channel, where some nodes couldn’t receive data from DC
and neighbor nodes (deaf nodes), while its transmission could be
received properly. Special packet structure is proposed to
minimize algorithm overhead. Performance comparison with
AODV protocol in terms of average throughput, reachability,
and protocol overhead is in progress.
