Item type:Publication, Access status: without files , M2M Communications in 5G: State-of-the-Art Architecture, Recent Advances, and Research ChallengesM2M communication offers ubiquitous applications and is one of the leading facilitators of the Internet of Things paradigm. Unlike human-tohuman communication, distinct features of M2M traffic necessitates specialized and interoperable communication technologies. However, most existing solutions offering wired or wireless connectivity have limitations that hinder widespread horizons of M2M applications. To cope with the peculiar nature of M2M traffic, the evolving 5G system considers the integration of key enabling networking technologies for ubiquitous connectivity and guaranteed QoS. This study outlines the state-of-the-art architecture, recent advances, and open research challenges in communication technologies for M2M. Also, an overview of considerable architectural enhancements and novel techniques expected in 5G networks is presented, followed by the resultant services and benefits for M2M communications.Publicationtype: Journal Article219 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , A radio resource sharing scheme for IoT/M2M communication in LTE-A downlink(2016-07-05); ; Machine-to-Machine (M2M) communication is an emerging technology which offers various ubiquitous services and is one of the main enablers of the Internet-of-Things (IoT) paradigm. Nevertheless, the notion of cellular-M2M communication is emerging due to the wide range, high reliability, increased capacity and decreased costs of future mobile networks. Consequently, M2M traffic is anticipated to pose severe challenges to mobile networks due to a myriad of devices sending and receiving small sized data. Moreover, mobile M2M traffic is expected to degrade the performance of traditional cellular traffic due to inefficient utilization of the scarce radio spectrum. This paper proposes a packet aggregation scheme to efficiently utilize radio spectrum for downlink M2M/IoT traffic. Therefore, the small sized data packets are aggregated at the Donor eNBs (DeNB) by considering the latest 3rd Generation Partnership Project (3GPP) standardized Long-Term-Evolution-Advanced (LTE-A) networks. Additionally, 3GPP standardized layer 3 inband Relay Nodes (RNs) are used for de-multiplexing of aggregated packets in downlink. The proposed scheme is validated through extensive system level simulations in an LTE-A based implementation for the RIVERBED modeler simulator. Our simulation results show that the number of M2M/IoT devices served per PRB (Physical Resource Block) is approximately doubled with the proposed packet aggregation scheme as compared to conventional relaying.Publicationtype: Conference Paper154
