Reliable data retrieval in Wireless Body Area Networks (WBAN) is critical in the patient monitoring and other medical services. The limitation of energy supply and the mobility of body sensors exacerbate the difficulties of efficient data transmission. This paper proposed the Information-centric data retrieval in WBAN (named by I-WBAN) to improve the reliability and efficiency, which was featured by: (i) adopting the…

An overview of ETSI TC SmartBAN MAC protocol
In this paper we introduce medium access control (MAC) protocol defined by ETSI TC (technical committee) SmartBAN (smart body area network). The key features of the protocol are a two-channel concept with different channels for data and control traffic, and a unique Multi-use Channel Access as one alternative channel access mode. The two-channel concept provides fast channel acquisition…
DMA-powered SDR processor exploiting DLP in LTE-Advanced
Software-defined radio (SDR) allows for the implementation and support of various wireless communication standards within a short development period. LTE-Advanced, which is the latest high-speed standard, demands a huge number of matrix calculations. We previously developed a digital signal processor (DSP) architecture with a direct memory access (DMA) function for exploiting data level parallelism (DLP) in LTE-Advanced…
Exploration of Centralized Car2X-Systems over LTE
Car2X-Communication is a method for data exchange between vehicles and infrastructure units to increase traffic safety and efficiency. Usually data processing and control is performed within the vehicle i.e decentralized. Centrally organized systems hardly get any attention in latest research, although they have many advantages. Since communication systems are improving, even safety-critical centralized systems become…
Investigation of Diagonal Antenna-Chassis Mode in Mobile Terminal LTE MIMO Antennas for Bandwidth Enhancement
A diagonal antenna-chassis mode is investigated in long-term evolution multiple-input-multiple-output (LTE MIMO) antennas. The MIMO bandwidth is defined in this paper as the overlap range of the low-envelope correlation coefficient, high total efficiency, and -6-dB impedance matching bandwidths. Utilizing the diagonal mode analysis, the MIMO bandwidth of the collocated MIMO antennas is improved efficiently at the…
