A robust M2M Gateway for effective integration of capillary and 3GPP networks

Machine to Machine (M2M) communication has gained much momentum in the recent past, both within academia and across different industries. Many of the M2M applications are required to send data to the M2M server connected directly or indirectly to the communication network such as 3GPP network. This requires connecting millions of M2M devices, apart from usual mobile devices, to the 3GPP network. However, this imposes a major deployment and management challenge, since the network was originally not designed to support billions of simultaneous connections. This paper discusses a practical M2M network deployment scenario and the architectural details. The paper provides a novel method to efficiently and effectively maintain and monitor multiplicity of M2M devices deployed for various applications such as monitoring, surveillance and tracking. Simulation result shows the benefits and practical uses of the proposed method.

An energy-efficient scheme for WiFi-capable M2M devices in hybrid LTE network

Machine to Machine (M2M) communication has gained much interest in the recent past, both within academia and across different industries. Power saving has become a priority issue recently due to accelerated growth of mobile devices with more and more processor power, more storage capacity, better display technology and much richer-applications. It assumes even greater significance when it comes to M2M devices since unlike hand-held mobile devices which has possibility to get re-charged after certain period of time, many of the M2M devices overall life is almost equal to its one-time charged battery life. This paper proposes an energy-efficient solution for M2M devices to minimize overall energy consumption. Simulation results based on OPNET simulator show that the proposed method significantly improves power saving, especially in time-tolerant M2M applications with long periodic report cycles.
