Wireless sensor networks continue to attract a lot of attention from academia and industry promoting large-scale deployments in applications related the Internet Things (IoT). Unfortunately, network containing large number nodes also leads difficulty configuring process assignment identifiers nodes. Various approaches have been proposed solve problems auto-configuration networks, however, still...

The IEEE-754 standard for Floating Point Arithmetic[1] that was in effect at the time of this seminar was adopted in 1985. That standard was intended for hardware implementation, although provisions were made for software implementation for operations. In addition to required operations, an appendix of recommended functions was also specified. Default exception handling was specified, and provi...

The IEEE Std 1149.7 holds the promise of great improvements for testing electronic circuits, when used along with other IEEE standards (particularly those that use the IEEE Std 1149.1 for test access and control). In this paper we describe “what” is the IEEE Std 1149.7, the reasons “why” we may consider to use it instead of IEEE Std 1149.1, and we highlight the application spectrum “where” this...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

Standard IEEE 802.15.4 offers three topology types and two channel access modes: slotted and unslotted CSMA/CA. The majority of a research work targets the performance of the slotted CSMA, despite the fact that wireless sensor networks are, by nature, intended to be multi-hop networks, where unslotted CSMA is the preferred media access control. This article analyzes the performance and limitati...

Quality of service (QoS) is a key problem in wireless environments where bandwidth is scarce and channel conditions are time varying and sometimes highly loss. Although IEEE 802.11 wireless LAN (WLAN) is the most widely used WLAN standard today, and the upcoming IEEE 802.11e QoS enhancement standard exists and introduces the QoS for supporting multimedia applications. This paper compares the pr...

IEEE 802.11i standard defines the security specifications of IEEE 802.11 series Wireless Local Area Network (WLAN). It is the replacement of the old security standard named Wired Equivalent Privacy (WEP), and it aims to eliminate all known attacks against WEP. It certainly provides solutions to the confidentiality, mutual authentication and integrity aspects of the WLAN security but not the ava...
