Abstract:

Event detection is one of the important applications of wireless sensor networks. However detection accuracy is limited by the amount of noise associa ted with the measurement and the reliability of usually low-end, inexpensive sensor nodes. It is necessary to take use of the characteristics of the WSN whose nodes are usually densely distributed and can percept the environment independently to eollaboratively detect events. This paper summarizes the s  tudies on the detection of the application-related and network-maintenance-related events and finally shows the merits and demerits of different kinds o f detection algorithms with different collaboration models.

Key words: event detection, boundary detection, fault detection, distributed collaboration
