Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. ...

    GEMS IoT

    IoT Device, Gateway, Server platform

    ...Bi-WSLP runs fast and provides a response rapidly, yet it takes a small code size occupies small memory. Bi-WSLP can be easily ported to various hardware platforms because it is coded in C, which is the most popular programming language for embedded systems. In addition, Bi-WSLP allows transmission of large-size data such as still images as well as common sensor data such as temperature and humidity. Bi-WSLP can be modified to conform to the IEEE 802.15.4 standard. Bi-WSLP supports bidirectional data transmission, so it allows a user not only to control the operation of sensor nodes immediately, but also to receive responses to the user almost in real-time.
