network and the unique security mechanism used in each one of these networks. The security consideration should satisfy a concise set of cryptographic and security mechanisms, single security policy framework, and configuration parameters policydependent. This may require consideration of system perspectives, taking into account the entire system and device lifecycle, ease-of-use and ease-of-deployment. Finally, we analyzed requirement of IoT security gateway system to improve vulnerability of sensor node.
