RSS transmissionsBuilding a Better Spam Trap: Choosing the Best Defense for Tomorrow's Emerging Email Threats
White Paper SonicWALL Anti-Spam/Email Security solutions apply an integrated multi-layered approach to protect organizations from inbound spam, phishing and email-borne malware, as well as from outbound data leaks and botnet... [13 Nov 2009]
White Space Networking With Wi-Fi Like Connectivity
White Paper WhiteFi builds on a simple technique, called SIFT, that reduces the time to detect transmissions in variable channel width systems by analyzing raw signals in the time domain. Networking over UHF white spaces is... [16 Sep 2009]
Network and Voice Management Software
White Paper Then came integration with the internet and the rise of Virtual Private Networks (VPNs) that exist conceptually above the physical infrastructure, followed by web services and all manner of transmissions using Internet... [15 Aug 2009]
A Ferry-Based Intrusion Detection Scheme for Sparsely Connected Ad Hoc Networks
White Paper Many of the approaches assume that there are sufficient neighbors to help monitor the transmissions and receptions of data packets by other nodes to detect abnormality. Several intrusion detection approaches have been... [01 Jul 2009]
A Game-Theoretic Analysis of Denial of Service Attacks in Wireless Random Access
White Paper Their goal is to evaluate the effects of malicious nodes that have the dual objectives of blocking the packet transmissions of the other selfish nodes as well as optimizing their individual performance measures. [30 Jun 2009]
China Youth Daily Modernizes Publishing With ProCurve Network
White Paper After a decade in operation, the 10Mbps network was technologically lagging and could no longer cope with new business demands such as daily transmissions of a large volume of news reports and large files of... [12 Jun 2009]
Epicor Software Case Study: Sterling Machine Company
White Paper Founded in 1956, Sterling is a precision manufacturer of helicopter transmissions, landing gear and structural parts. During the early 1990s, however, Sterling's business wasn't always looking up. Their customers were... [30 May 2009]
Analysis of Transparent Mode IEEE 802.16j System Performance With Varying Numbers of Relays and Associated Transmit Power
White Paper However, the overall throughput gain drops as the transmit power at the Relays (RSs) decreases despite the fact that a greater number of concurrent transmissions can be achieved due to less interference among the RSs'... [23 Apr 2009]
A New Resource Allocation Scheme for IEEE 802.16-Based Networks
White Paper With the ability of broadband wireless access of an IEEE 802.16 system, a proper resource allocation scheme for packet transmissions is imperatively needed. IEEE Standard 802.16 sets the stage for broadband wireless... [23 Apr 2009]
Bandwidth Allocation With Half-Duplex Stations in IEEE 802.16 Wireless Networks
White Paper However, although the network can be operated in Frequency Division Duplex (FDD) mode (that is, transmissions from the BS (downlink) and SSs (uplink) occur on separate frequency channels), the standard supports SSs with... [23 Apr 2009]
Bolster Network Security With VPN Load Balancing and Redundancy
White Paper Today's Wide Area Networks (WANs) are experiencing increased saturation with the deployment of bandwidth-intensive applications, increased numbers of users, and the need for reliable security transmissions. [22 Apr 2009]
Is Random Network Coding Helpful in WiMAX?
White Paper However, it sacrifices resilience in time varying channels, and it may under-utilize the wireless medium in the cases of multi-path and multi-hop transmissions. The IEEE 802.16 standard, or WiMAX, has emerged to... [22 Apr 2009]
Real-Time Video Multicast in WiMAX Networks
White Paper To address this challenge, a combination of approaches are considered using multicast, layer encoded video and adaptive modulation of transmissions. IEEE 802.16e WiMAX is a promising new technology for broadband access... [22 Apr 2009]
System Level Performance of Cellular WiMAX IEEE 802.16 With SDMA-Enhanced Medium Access
