During the last years the application areas and corresponding requirements for Wireless Sensor Networks (WSN) raised due to limited resources of devices and requirements of the application. The scenarios (e.g. home networks) call for an integration of a WSN into an existing IP-based infrastructure which is realized by 6LoW-PAN. To save resources and to ensure a long life time of the WSN resource consuming tasks such as transmissions must be reduced. Therefore, we present a Compressed IPFIX protocol. It optimizes the transmission by reducing the packet size and the transmission amount by separation between meta information and data. Additional tasks can be performed on top of IPFIX to optimize the efficient usage of the limited resources.
