This paper presents a very large-scale integration (VLSI) circuit design of a micro control unit (MCU) for wireless body sensor networks (WBSNs) in cost-intention. The proposed MCU design consists of an asynchronous interface, a multisensor controller, a register bank, a hardware-shared filter, a lossless compressor, an encryption encoder, an error correct coding (ECC) circuit, a universal asynchronous...
In this paper, an efficient micro control unit (MCU) design is proposed for wearable electronics and wireless sensor networks. It consists of an asynchronous interface, a register bank, a reconfigurable filter, a lossless data encoder, an encryption encoder, an error correct coding (ECC) encoder, a power management, a resolution controller and a multi-sensor controller. The asynchronous interface...
In order to manage the Internet of things in a flexible and efficient way, this paper proposes a novel M2M framework using smart/HetNet gateways. Our approach is not only compatible to the M2M standard, but also enables the community-based coordination among gateways and devices. With smart and HetNet gateways, various types of requirements and applications can be fulfilled and handled at a local...
An efficient VLSI design of lossless electrocardiogram (ECG) encoder is proposed for wireless body sensor networks. To save wireless transmission power, a novel lossless encoding algorithm has been created for ECG signal compression. The proposed algorithm consists of an adaptive predictor based on the fuzzy decision control, and an entropy encoder including a two-stage Huffman coding. The VLSI architecture...
Inter-vehicular communications (IVCs) are now considered as a way to realize active safety, for example, by providing the position information of each other or the potential danger warning by wireless communications. We have worked on a flooding protocol over vehicular ad hoc networks (VANETs) to efficiently disseminate the information for the sake of active safety applications, such as the positions...
