Wireless Signal Processing & Networking Workshop:
Advanced Wireless Technologies

Date: 21 December (Friday),2012

Venue: Main Conference Room, CENTER HALL Building, Engineerings, Tohoku University

Time: 11:15~

Title: Large-Scale Machine-to-Machine (M2M) Mobile Networking

Speaker: Prof. Phone Lin

Affiliation: National Taiwan Universit


  In the M2M mobile networks, the number of devices in M2M mobile networks is hundreds of thousands times larger than that in the existing mobile networks. With the growing number of devices, the volume of signaling transmissions for networking functionalities increases drastically. More network bandwidth is consumed to handle such surge in signaling transmissions, resulting in less network bandwidth available and poor robustness/reliability for data transmission of existing mobile applications and future M2M applications. Furthermore, network congestion may occur due to mass concurrent data of M2M applications, such as when bursty data are generated by M2M devices in an interval.

Networking functionalities with less signaling overhead is desired in the M2M mobile networks so that more network bandwidth can be available to serve mass concurrent data transmission. Energy conservation and effective packet routing also becomes thorny issues, especially with incoming mass concurrent M2M data. Finally, security functions on M2M mobile networks face the challenge of key management for large-scale M2M mobile network, because the network requires large quantity of key exchanges and key storage space.

This talk will identifies the technical challenges that may exist in the existing mobile network to support large-scale machine-to-machine communications, and enumerates possible solutions that may be applied to resolve the challenges. Some current research results related to the robust and efficiency M2M networks will also be presented in this talk.
