This paper presents a solution to count all moving vehicles in a target region. This is a large-scale counting that cannot be easily solved without a global view. However, there is no single force that can provide such a global view. To achieve an accurate result without either double- or miscounting, the local counting at each checkpoint is synchronized in our wireless communication by using the...
Due to the low cost and capabilities of sensors, wireless sensor networks (WSNs) are promising for military and civilian surveillance of people and vehicles. One important aspect of surveillance is target localization. A location can be estimated by collecting and analyzing sensing data on signal strength, time of arrival, time difference of arrival, or angle of arrival. However, this data is subject...
End-users agree that data surveillance approach are an interesting new topic in the field of B/S and C/S structure. In fact, few system administrators would disagree with the development of data surveillance approach, which embodies the extensive principles of algorithms. In this work, we show that even though Boolean logic and red-black trees can collude to accomplish this objective, the famous data...
We propose a new tracking framework by organizing nodes into a polygonal spatial neighborhood in order to detect and track unauthorized traversals in surveillance wireless sensor networks. During a tracking, the neighborhood is further constructed ahead of the target traversal, and this features a timely forwarding with guaranteed delivery property. Instead of estimating future movement and position...
