Wifi là tên gọi thường dùng mà chúng ta hay gọi một mạng không dây nội bộ Wireless Local Area Network (WLAN). Mạng không dây mang đến sự tiện lợi rõ rệt so với kiểu kết nối bằng cáp mạng truyền thống. Thiết bị nào được trang bị anten thu sóng là có thể kết nối vào Wifi, miễn là ở trong vùng phủ són[r]

Time synchronization plays an important role in wireless sensor networks which aim at bridging the gap between the physical and virtual world. In this thesis, two time synchronization approaches are investigated and implemented for BTnodes: global continuous clock synchronization and local on demand[r]

Energy efficient routing protocols are consistently cited as efficient solutions for Wireless Sensor Networks (WSNs) routing. The area of WSNs is one of the emerging and fast growing fields which brought low cost, low power and multifunctional sensor nodes. In this paper, we examine some protocols r[r]
