• Introduction• Wireless Sensor Network• Gateway Design and Development• Conclusion
Outline
“Commercial, off-the-shelf (COTS) is a term for software or hardware, generally technology or
computer products, that are ready-made and available for sale, lease, or license to the general public.”

• Gateway method is the easy solution for integration WSN and IP
• COTS device may increase flexibility for adding the service software and in the same time reduce the cost
• COTS reduce installation cost for already installed WSN
• Increase system interoperability
