World Wireless Sensors and Wireless Sensor Networks (Technical Insights)
Frost & Sullivan, Dec 2004
Emerging Standardization Expected to Spur Uptake of Wireless Sensor Networks
The market is transitioning from wireless sensor networks based on proprietary platforms toward a standards-based environment with the emergence of the IEEE 802.15.4 standard and the recently ratified ZigBee standard. Standardization is expected to improve interfacing capabilities and allow end users to migrate to a new service provider without reworking the entire solution and incurring significantly high costs. With the growing standardization of wireless technology, the market is likely to become more streamlined allowing developers to operate on a common platform and improve interoperability, explains the analyst of this research.
In addition, the introduction of standards enables original equipment manufacturers (OEMs) to increase profitability by producing certified devices in high capacities thereby taking advantage of economies of scale. Device providers and system integrators can also work with certified documented protocols giving them more flexibility and freedom for increasing functionality as and when required and with additional scalability options.
Industrial and Building Automation Presents Numerous Opportunities for Wireless Sensor Networks
Given its numerous advantages over a wired network, wireless sensor network technology is expected to grow exponentially and gain a stronghold across industry verticals such as building automation and industrial applications. The benefits of wireless sensor networks in these two sectors are enormous and will serve the purpose of demonstrating their capabilities. Participants in this market need to educate end users regarding the obvious cost benefits, ease of deployment, retrofitting applications, and scalability to increase the uptake of wireless sensor networks, says the analyst.
For instance, building automation applications such as lighting and occupancy sensors demonstrate high energy efficiency levels, quicker return on investment, and ease of deployment and removal. Such devices are expected to find increasing acceptance among major retailers such as Wal-Mart and Home Depot where optimal energy consumption and reduced energy costs are a primary concern. In the industrial automation space, the largest opportunity for wireless sensor networks lies in sensing devices in remote or inaccessible areas such as nuclear plants, oil and gas fields, and high temperature furnaces.
Scaling Network Size Remains a Significant Challenge
Although wireless sensor networks are easy to deploy at exceptionally low costs in comparison to a wired network, there are several technical challenges such as network management, monitoring tools, optimal gateway design, and several other hardware considerations that need to be addressed. However, the biggest challenge to date is increasing the average deployable network size from the existing few hundred nodes to a thousand nodes or more. Most companies in this field are working toward systems that can perform robustly and efficiently when scaled up to a size of around 500 nodes. Test demonstrations of 800 node networks are have already been completed successfully but more concerted efforts are required for gaining a competitive advantage in the mainstream market.
This research analyzes emerging developments that will enable wireless sensor networks to make an impact across various industry verticals. In addition to identifying major technology drivers and challenges, the research provides in-depth application analysis. Participants can also easily identify potential collaborators to stay ahead of the competition and remain shoulder-to-shoulder with critical developments.
