A Wireless Electricity Meter Reading Strategy Based on Lightweight IPv6

Abstract

In order to reduce the networking time and improve the success rate of wireless electricity meter reading, a RPL routing control strategy based on lightweight IPv6 is proposed. A tree network topology is built by the strategy, and the IPv6 addresses of nodes are generated according to serials number of electricity meter and vendor code. The parent nodes are chosen by considering three routing metrics including the network depth, the strength of received signal and the Expected Transmission Count (ETX). In addition, a packet retransmission mechanism and concentrator file updating mechanism are adopted to improve the efficiency and success rate of electricity meter reading. The test results show that the wireless electricity meter reading strategy can construct the network rapidly and improve the efficiency of electricity meter reading.
