Wireless Building Control Communications Using WLAN Mesh

Route Discovery

On Demand route discovery
Triggered whenever a source node wants to communicate with other node for which there is no entry in the former s routing table.
Source node broadcasts a RREQ (Route REQuest) across the network. Nodes receiving RREQ will update their information by setting up backward pointers to the source node in their route tables (Reverse Route set up)
A RREP (Route REsPonse) packet is sent back to the source node fr ....etc

With the increasing demands for new data and real-time services, wireless networks should
support calls with different traffic characteristics and different Quality of Service (QoS)
guarantees. In addition, various wireless technologies and networks exist currently that can
satisfy different needs and requirements of mobile users. Since these different wireless
networks act as complementary to each other in terms of their capabilities and suitability for
different applications, integration of these networks will enable the mobile users to ....etc

Abstract


This paper outlines some of the technical challenges that must be met, particularly with respect to handset radio design, that will allow coexistence between Cellular and WLAN modes of operation. Various aspects of coexistence are considered, such as the demands of the RF architecture, interference issues, chip set fabrication and cost issues. Conclusions are then drawn as to the defining aspects of WLAN and Cellular convergence ....etc

Enterprise FMC and the T-Mobile HotSpot@Home service
In recent years the features of dual-mode devices (cellular voice and data clients with additional Wi-Fi
radios) have grown increasingly sophisticated. The burgeoning capabilities of these devices have attracted
the attention of IT staff at enterprises and universities with campus environments because of potential
synergies with already installed wireless LANs. More specifically, the potential exists for a user to carry a
single device that leverages Wi-Fi coverage where cellular ....etc

Introduction
The need for VoIP technology, which was presented by the network managers with practical solutions for combining voice and data over a network. Showed that VoIP can be very useful and much cheaper alternative to circuit-switched voice networks, and promises that can extend these benefits to the higher performance of teams of mobile workers in a company.
As a step to be able to continue to grow the business, mobile communications are considered as very im ....etc

Abstract This paper presents a novel approach to building a WLAN-based location fingerprinting system. Our algorithm intelligently transforms received signal strength (RSS) into principal components (PCs) such that the information of all access points (APs) is more efficiently utilized. Instead of selecting APs, the proposed technique replaces the elements with a subset of PCs to simultaneously improve the accuracy and reduce the online computation. Our experiments are conducted in a realistic WLAN environment. The results show that the mean e ....etc
