Metrical calibration is very critical for the accuracy of a 3d sensor. Measuring uncertainty of about 1:3000 of the z-range requires a calibration accuracy of about 1:104 . Severa...
Wireless Sensor Networks (WSNs) have been widely used in environment monitoring to collect useful information. Packet broadcasting is an essential function for establishing a comm...
With the development of location aware sensor applications, location determination has become an increasingly important middleware technology. Numerous current technologies for lo...

Due to the fragility of small sensors, their finite energy supply and the loss of packets in the wireless channel, reports from sensors may not reach the sink node. In this paper ...
Wireless Sensor Networks are extremely vulnerable against any kind of internal or external attacks, due to several factors such as resource-constrained nodes and lack of tamper-res...
