This report summarizes research activities of the investigating R&D
committee on sensor networks of IEEJ. The committee consists of 16 members
from electric power and telecommunication companies, railway and electrical
research institutes, manufacturers and a university, and extensive research
activities are recognized from October 2005 for 2 years. Chapter 2 of this
report deals with study trends of sensor networks: waiting current reduction
technology, timing control of packet transmission, low power consumption,
security and privacy, key distribution, position and location estimation,
fault sensing, time synchronization. In chapter 3, demonstration and trial
of sensor network are described: trials of electric power companies and
railway companies, pedestrian assistance ITS, demonstrations of Aichi EXPO
and Kurashiki shi, Ubila project of government initiatives. In chapter
4, development of sensor nodes are introduced by three member companies.
In chapter 5, standardization trend in sensor networks is summarized: Bluetooth,
UWB, ZigBee, IETF, and radio frequency allocation of Japan is described.
