TL;DR: This paper presents an AES encryption hardware core suited for devices in which low cost and low power consumption are desired and constitutes of a novel 8-bit architecture and supports encryption with 128-bit keys.

TL;DR: A framework in which a middleware distributes the application processing to a WSN so that the application lifetime is maximized is recommended, and an approach providing a complete distributed environment for applications is absent.

TL;DR: A novel algorithm to rapidly create a high quality network plan for IEEE 802.11 based WLAN according to assigned design requirements was used in WLAN planning for a suburb, which is under development in Tampere-Lempaala area in Finland.

TL;DR: This paper analyses the performance of IEEE 802.15.4 Low-Rate Wireless Personal Area Network (LR-WPAN) in a large-scale Wireless Sensor Network (WSN) application and finds that the minimum device power consumption is as low as 73 μW, when beacon interval is 3.93 s, and data are transmitted at 4 min intervals.

TL;DR: The design and implementation of the Bluetooth local positioning application based on received power levels, which is converted to distance estimates according to a simple propagation model, and the extended Kalman filter computes a 3D position estimate on the basis of distance estimates.
