By the variety of its applications, Internet of things (IoT) is believed to be able to improve people’s daily life in many aspects and thus is going to prevailing everywhere in the near future. In light of the high connection demand from IoT, i.e., a huge market, the next generation of wireless cellular network, the 5G network, has made IoT connections one of its primary service categories. NB-IoT is hence proposed in 3GPP spec Rel-13 and will be enhanced in Rel-14 as its Cellular IoT solution to provide low power, low data rate, but long distance (wide coverage) wireless connections. In this talk we will discuss the pros and cons of celluar IoT and introduce the current status of the standardization of 3GPP NB-IoT.

Jen-Yeu Chen received the BS and MS degrees from National Cheng Kung University, Tainan, Taiwan, R.O.C., and the PhD degree from Purdue University, USA, in 2007, all in electrical engineering. Prior to studying at Purdue University, he was with Chunghwa Telecom Laboratories Co., Ltd., Taiwan, as an associate researcher. He is currently an associate professor with the Department of Electrical Engineering, National Dong Hwa University, Hualien, Taiwan. His research interests span over the areas of networking, control and communications. In particular, in recent years, he applies distributed randomized algorithms and probabilistic methods to solve problems arising in wireless ad hoc networks, wireless sensor networks and multi-agent systems. Some problems he has been tackling are data aggregation/fusion, distributed consensus, power control, scheduling and synchronization in wireless ad hoc networks, intrusion detection in wireless network with Random Linear Network Coding (RLNC), and coordinated probabilistic map construction by the mobile robotic sensor network (a multi-agent system). He has worked on applying distributed optimization techniques to the issues of cross-layer design in wireless networks such as the joint scheduling, routing as well as channel assignment in wireless networks, and optimal bit allocation for H.264/AVC over wireless time-varying channels. Other researches with decent results are secure wireless network coding schemes, efficient multicasting protocols, analysis framework for HetNets and small-cell mobile networks, and scientific cloud computing (HPC and soft computing over iterative MapReduce runtime –Twister and Apache Hama). He is currently a delegate of the 3GPP RAN and SA meetings. He is applying Cloud computing techniques to solve complicated optimization problem raised in next generation mobile networks with small and heterogeneous cells.
