: We propose a novel data collection architecture, called Ring-based Information Collection Architecture (RICA), for sensor networks. In the RICA scheme, sensors are organised into...
Wireless sensor networks have attracted increasing attentions considering their potentials for being widely adopted in both emerging civil and military applications. A common prac...
Sensor nets have many undisputed fields of application. A paradigm of communication is the use of one control channel in the MAC layer. We challenge this paradigm for nodes with v...
Abstract--Recent advances in wireless sensor technology facilitate the development of remote healthcare systems, which can significantly reduce the healthcare cost. Despite the ini...
Data missing is a common problem in database query processing, which can cause bias or lead to inefficient analyses, and this problem happens more often in sensor databases. The re...
