Enhanced Ad-Hoc Routing Protocol over Electrical Power Lines

This book proposes a routing algorithm 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 pröle 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 could have a problem in receiving from DC and neighbor nodes (deaf nodes), while its transmission could be received properly. Special packet structure is proposed to minimize algorithm overhead. The performance is being compared to LOADng, LOADng-CTP and AODV in terms of protocol overhead, end-to-end delay, packet delivery ratio and memory requirements.
