The IEEE 802.16 standard was designed for Wireless Metropolitan Area Network (WMAN). The coverage of this new technology is expanded up to 50 km. IEEE 802.16 also has inherent QoS ...
Mobile elements, which can traverse the deployment area and convey the observed data from static sensor nodes to a base station, have been introduced for energy efficient data co...
The identification of holes in a wireless sensor network is of primary interest since the breakdown of sensor nodes in a larger area often indicates one of the special events to ...
This paper proposes a secure encrypted-data aggregation scheme for wireless sensor networks. Our design for data aggregation eliminates redundant sensor readings without using encr...
This work presents a user position management system for Wi-Fi networks. The location system is based on access point coverage range and beacon devices. The implementation was mad...
