Using directional antennas in wireless ad hoc networks can significantly improve network performance. However, the deafness problem greatly limits the network performance. This pa...
In this paper, we describe an on-going project called Concept and Sensor Networks (CSN). The development of this project has been described in past PSMP workshops [1]. The purpose ...
Clock synchronization is critical for Wireless Sensor Networks (WSNs) due to the need of inter-node coordination and collaborative information processing. Although many message pa...
Outlier detection in wireless sensor networks is essential to ensure data quality, secure monitoring and reliable detection of interesting and critical events. A key challenge for...
In this paper, we propose a new control method to cover the “holes” in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are d...
