This paper deals with the reliability of random access (RA) protocols formassive wireless smart grid communication (m-SGC). We propose and analyze animproved grant-free RA (GF-RA) protocol for critical SG applications understrict QoS m-SGC requirements. At first, we discuss the main features of the SGneighborhood area network (NAN) architecture. We explore the main features oflow-rate machine-type wireless networks, and also we describe a technologycharacterization of wireless neighborhood area networks (WNAN) in medium-rangecoverage applications. We propose a new-improved irregular repetition slottedALOHA, combing Raptor codes and irregular ALOHA, namely RapIRSA random accessprotocol, to better respond to critical high-reliability QoS requirements undera 5G network perspective. Then, we compare and comprehensively analyze theproposed RapIRSA protocol with two existing RA protocols, the IRSA protocol,and the classical Slotted Aloha. Finally, We summarize the potential challengesin implementing the proposed RA protocol for SG critical applicationsconsidering many smart sensors (SS).
