Abstract
The advanced metering infrastructure (AMI) with smart metering networks, which enables the two-way information exchange between utilities and end-users, is the critically important component of the overall smart grid architecture. In this paper, we propose a network coding based QoS-provisioning MAC protocol for wireless smart metering networks, which aims at providing reliable and low-latency communications services between smart meters and coordinator of the utilities. In particular, to efficiently utilize the limited bandwidth resource, we develop our proposed MAC protocol based on the contention-free orthogonal frequency division multiple access (OFDMA) methodology. Our proposed MAC protocol incorporates the opportunistic resource allocation, cooperative grouping, and network coding technique. Under our proposed MAC protocol, the coordinator adaptively allocates the resource blocks to each smart meters based on the channel conditions between the coordinator and the smart meter and among the smart meters. Also conducted are simulations to verify and evaluate our proposed MAC protocol.
