Wireless Local Area Networks (WLANs) experience a growing popularity recently. Where WLANs were primarily used for niche applications in the past, they are now deployed as wireless extensions to computer networks. The increase of the datarates from 2 Mbps up to 11 Mbps for roughly a constant price has played a major role in this breakthrough. As a consequence, an even greater success can be envisioned for the more recent OFDM-based WLAN standards in the 5 GHz band, which offer up to 54 Mbps. At IMEC we have realised this potential already several years ago and have established a successful research programme on OF- based WLAN. In 1995, we started our research on wireless OFDM in the frame of a – operation project with SAIT, a Belgian telecom company. The goal of the project was to establish a robust network for industrial environments. This resulted in a first OFDM chip, supporting QPSK, for wireless networking at the end of the project (1999). 1999 was also the start of an intense co-operation with National Semiconductor Inc., which resulted in a second generation ASIC in 2000. This OFDM processor supports up to QAM-64 and has a more optimal channel estimation algorithm.

In this 21st century era, people tend to find another space for improving everything, including technology. This includes the possibility of reaching out more using routers and gadgets. Even businesses and mode of transportation involves a high demand on using a WMN or Wireless Mesh Network. WMN which is commonly known as one of the primary technology nowadays. This also helps in terms of understanding the network connectivity at any time, at a low cost. In Wireless Mesh Network, there are two kinds of a technique used, the Mesh Nodes and Mesh Clients. This two are known to be the backbone, the bridge, the way of reaching out for connectivity. One key challenge in adopting wireless mesh networking is the capacity of effective throughout that can be offered to the clients. Due to the broadcast nature of the wireless medium, signals transmitted from different devices over the same channel will result in a probable connection loss. Despite the probability of problems that may occur, the WMN is starting to grow its volume into a larger scale of communication. This book is a significant platform to discuss its future competencies and proficiencies in the communication of a greater ecosystem using Wireless Mesh Network.

Secure Localization and Time Synchronization for Wireless Sensor and Ad Hoc Networks


Free Download Secure Localization and Time Synchronization for Wireless Sensor and Ad Hoc Networks by Radha Poovendran, Sumit Roy, Cliff Wang
English | PDF | 2007 | 396 Pages | ISBN : 0387327215 | 58.3 MB
Localization is a critical process in mobile ad hoc networks and wireless sensor networks. Wireless sensor node or MANET devices need to know the network’s location or its relative location, with respect to the rest of the network neighbors. However, due to the open spectrum nature of wireless communication, it is subject to attacks and intrusions. Hence the wireless network synchronization needs to be both robust and secure. Furthermore, issues such as energy constraints and mobility make the localization process even more challenging.

This book contains revised contributions byt he speakers oft he 1s t IEEE Workshop on Wireless Communication Circuits and Systems, held in Lucerne, Switzerland, from June 22-24, 1998. The aim oft he workshop was to apply the vast expertise oft he CAS Society in the area of circuit and system design to the rapidly growing field of wireless communications. The workshop combined presentations by invited experts from academia and industry with panel and informal discussions. The following topics were covered: RFSystemInteg ration (single chip systems, CM OS RF circuits), RFFront End Circuits (CMOS RF oscillators, broadband design techniques), Wideband Conversion for Software Radio (A/D conversion issues, wideband sub sampling, low spurious A/D conversion), Process Technologies for Future RF Systems (Si, SiGe, GaAs, CMOS, packaging technologies), DSPforWireless Communications (DSP algorithms, fixed point systems, DSP for baseband applications), Blind Channel Equalization (adaptive interference suppression, design techniques, channel estimation). The workshop was a great success, with over 130 participants from 19 countries, from the U. S. to Europe and Asia, including a large contingent of participants from industry (60% ). Feedback from the participants showed that the carefully selected combination oftutorial like lectures with lectures onspecialized and advancedtopics was a feature oft he workshop that was particularly a ppreciated. Duet o therelatively strong involvemento findustry – both in theform of lecturers and listeners – a high level ofd i scussion was attained in bothpanel sessions and informal gatherings.
