In the WSN- (wireless sensor network-) based surveillance system to detect undesired intrusion, all detected objects are not intruders. In order to reduce false alarms, human detection mechanism needs to determine if the detected object is a human. F

In some surveillance system, it is important to detect undesired intrusion in a monitored space. However, all detected objects are not intruders. In order to reduce the false alarms, it is needed to determine if the detected object is human. Thus, we

In WSN (Wireless Sensor Networks) based surveillance system, it needs to know the occurrence of events or objects and their locations, because the data have no meaning without location information. Using traditional 2D localization mechanisms provide
