Abstract-The systems based on intelligent sensors are currently expanding, due to theirs functions and theirs performances of intelligence: transmitting and receiving data in real-time, computation and processing algorithms, metrology remote, diagnostics, automation and storage measurements…The radio frequency wireless communication with its multitude offers a better solution for data traffic in this kind of systems. The mains objectives of this paper is to present a solution of the problem related to the selection criteria of a better wireless communication technology face up to the constraints imposed by the intended application and the evaluation of its key features. The comparison between the different wireless technologies (WiFi, Wi-Max, UWB, Bluetooth, ZigBee, ZigBeeIP, GSM/GPRS) focuses on their performance which depends on the areas of utilization. Furthermore, it shows the limits of their characteristics. Study findings can be used by the developers/ engineers to deduce the optimal mode to integrate and to operate a system that guarantees quality of communication, minimizing energy consumption, reducing the implementation cost and avoiding time constraints.

Abstract-The metrology field has been progressed with the appearance of the wireless intelligent sensor systems providing more capabilities such as signal processing, remote multisensing fusion etc. This kind of devices is rapidly making their way into medical and industrial monitoring, collision avoidance, traffic control, automotive and others applications. However, numerous design challenges for wireless intelligent sensors systems are imposed to overcome the physical limitations in data traffic, such as system noise, real time communication, signal attenuation, response dynamics, power consumption, and effective conversion rates etc, especially for applications requiring specific performances. This paper analyzes the performance metrics of the mentioned sensing devices systems which stands for superior measurement, more accuracy and reliability. Study findings prescribe researchers, developers/ engineers and users to realizing an optimal sensing motes design strategy that offers operational advantages which can offer cost-effective solutions for an application.

“…GMSK (Gaussian-filtered minimum shift keying) [3,4], in which a premodulation Gaussian filter is introduced to MSK, and is one of the promising modulation schemes for single-channel-per-carrier (SCPC) digital mobile communications in terms of its narrow-band and sharp cut-off property of the power spectrum and its constant envelope property [4]. While the premodulation filtering is very effective in reducing the out-of-band power of the modulated wave, it causes degradation of bit-error-rate (BER) performance versus signal-to-noise ratio due to the increased intersymbol interference [3,4,5]. In this work, premodulation Laplacian filtered minimum shift keying (LMSK) is proposed as an effective digital modulation, and is compared to GMSK.…”

This paper describes a new method of premodulation filtered MSK called Laplacianfiltered minimum shift keying (LMSK). LMSK is proposed as a method for achieving good spectral efficiency over regular MSK and it turns out to achieve improvement in error rate performance over the known Gaussian filtered minimum shift keying (GMSK). To compare the behavior of the system under the proposed new technique, bandwidth efficiency (i.e., bps/Hz) and fractional out-of-band power is used. As well, error rate performance in such systems is used in the evaluation of this work.
