“…Furthermore, assumptions can be made based on the number of transistors or gates in the design. Therefore, to estimate the system hardware complexity we can show the logic layout [19]. CSMA/CA model could support an operation frequency up to 200 MHz since 5 ns clock period is used for the simulation.…”

IEEE 802.15.4 is an important standard for Low Rate Wireless Personal Area Network (LRWPAN). The IEEE 802.15.4 presents a flexible MAC protocol that provides good efficiency for data transmission by adapting its parameters according to characteristics of different applications. In this research work, some restrictions of this standard are explained and an improvement of traffic efficiency by optimizing MAC layer is proposed. Implementation details for several blocks of communication system are carefully modeled. The protocol implementation is done using VHDL language. The analysis gives a full understanding of the behavior of the MAC protocol with regard to backoff delay, data loss probability, congestion probability, slot effectiveness, and traffic distribution for terminals. Two ideas are proposed and tested to improve efficiency of CSMA/CA mechanism for IEEE 802.15.4 MAC Layer. Primarily, we dynamically adjust the backoff exponent (BE) according to queue level of each node. Secondly, we vary the number of consecutive clear channel assessment (CCA) for packet transmission. We demonstrate also that slot compensation provided by the enhanced MAC protocol can greatly avoid unused slots. The results show the significant improvements expected by our approach among the IEEE 802.15.4 MAC standards. Synthesis results show also hardware performances of our proposed architecture.

“…While simple mote systems typically consist of a small processor and some interface logic only, smart motes often contain additional system components for enabling efficient data processing within the motes, e.g. coprocessors, reconfigurable units [3], or ASIC extensions [1]. The prototyping of smart motes, which is the primary objective of our platform, therefore requires the use of a FPGA with a considerable amount of logic resources.…”

“…Such smart sensor networks therefore characteristically require data processing to be performed locally on the network nodes (motes). Because the motes also have to meet stringent energy constraints, mote architectures for smart sensor networks typically comprise dedicated hardware components to achieve low energy consumption for data processing [1,2,3], so that the design of smart mote systems may get rather complex.…”

In this paper, a new concept for a very flexible and modular prototype platform for rapid prototyping of wireless sensor networks is presented. We propose to use a FPGA with high gate count as core of the platform. The FPGA is utilized to attain 3 major goals for the prototype platform: to emulate arbitrary mote architectures even including smart motes with high system complexity, to realize flexible interfaces to sensors and radio transceivers, and to embed versatile debugging and system monitoring functionality in the mote prototypes. The presented prototype platform is suitable to realize complete sensor networks based on different mote architectures, different wireless communication schemes, and arbitrary application domains. The design concepts and implementation aspects of the platform are presented and discussed in detail.

In this research, we propose and develop a remote medical-care support system for supporting nurses, care managers and care helpers during their work. The proposed system has two functions: a multi-point communication function using video images and voice, and vital signs data auto-uploading and referring function. In this paper, we present the proposed remote medical-care support system and report the field experiment results using the proposed support system in a medical-care support center. The experiment results show that proposed system has a good performance.
