Design and Implementation of Low-Area and Low-Power AES Encryption Hardware Core
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.
Journal ArticleDOI
Comparative Rate-Distortion-Complexity Analysis of HEVC and AVC Video Codecs
TL;DR: The rate-distortion-complexity of High Efficiency Video Coding (HEVC) reference video codec (HM) and compares the results with AVC reference codec (JM) is analyzed and the bottlenecks of HM codec are revealed and implementation guidelines for future real-time HEVC codecs are provided.
Journal ArticleDOI
A survey of application distribution in wireless sensor networks
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.
Proceedings ArticleDOI
Genetic Algorithm to Optimize Node Placement and Configuration for WLAN Planning
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.
Proceedings ArticleDOI
Ensuring the QoS requirements in 802.16 scheduling
TL;DR: This work proposes a simple, yet efficient, solution for the WiMAX base station that is capable of allocating slots based on the QoS requirements, bandwidth request sizes, and theWiMAX network parameters.
