Boundary Detection in 2-D and 3-D Wireless Sensor Networks.pdf

In order to track and detect continuous natured objects in wireless sensor networks, large number of sensor nodes are involved. These continuous objects like bio-chemical diffusions, forest fires, oil spills usually spread over larger area. The nodes that sense the phenomena need to communicate with each other for exchanging the information and also send sensing information to sink, possibly by passing through many intermediate nodes. In this paper, we have reviewed boundary detection in 2-D wireless sensor networks as well as in 3-D wireless sensor networks. A comparative study between the both has also been shown. The various challenges encountered in 3-D wireless sensor networks have also been discussed.
