Product Enhancement: New Feature for NovaRoam Mobile Routers Improves Wireless Range and Link Reliability21 December 2005
Nova Engineering, Inc. announces the release of a new feature for its NovaRoam(R) Mobile Router product line, called Unidirectional Link Detection and Avoidance (ULDA). NovaRoam Mobile Routers offer long-range, high-speed and secure mobile data communications for public safety, military, and remote monitoring and control applications in countries across the globe.
NovaRoam incorporates advanced mobile ad hoc networking -- otherwise referred to as mesh networking -- technology to facilitate adaptable wireless data communications in these highly demanding environments.
"Our customers' applications demand that their network connections are always available," said Ryan Canning, NovaRoam product manager, "and because their application environments are not inherently controlled, many ad hoc routing algorithms become susceptible to unidirectional link conditions. Unidirectional links occur when a network node can hear a second node but the second node cannot hear the first, leading to increased packet loss, decreased user throughput and a shorter communication range. The ULDA feature helps to solve these problems by substantially improving link reliability."
The new ULDA feature is the direct result of changes to Nova's implementation of the AODV mobile ad hoc routing algorithm. With ULDA, the NovaRoam automatically discovers unidirectional link conditions prior to establishing a new route. Once bad routes are detected, they are designated accordingly and avoided by the NovaRoam so it can continue to search for a bidirectional link.
According to Nova Engineering, by avoiding these detrimental unidirectional links, the user experiences increased network uptime, higher throughput, a longer communication range, and more stable operation overall. ULDA builds upon NovaRoam's already impressive communication coverage area, throughput and network adaptability.
"The ULDA feature is another practical enhancement to NovaRoam's mesh networking technology," said Michael Rauf, director of products for Nova Engineering. "Not only can our customers communicate over greater distances with this upgrade, but the reliability of their wireless network connection is improved as well."
The new ULDA feature is inherent in the NovaRoam product line for new customers; existing customers can download the feature at no cost to update standard and custom NovaRoam models in the field.
