Gathering Sensor Data in Home Networks with IPFIX

Abstract

Abstract. New developments in military, health and home areas call for new approaches for data acquisition in real-time. Such application areas frequently include challenging requirements for collection, processing and analysis of environmental data. Wireless Sensor Networks can collect such environmental data efficiently. Collected sensor node data needs to be transmitted in an efficient way due to limitations of sensor node resources in battery power and available bandwidth. In this paper, we present a method for efficient transmission of sensor measurement data using the IETF standard IPFIX. We show that its template based design is suitable for efficient transmission of senor data with low bandwidth consumption. In this paper, we present the protocol and its implementation in Wireless Sensor Networks (WSNs). Additionally, a header compression scheme is introduced which further reduces communication cost during data transmission.

Collecting sensor data using compressed IPFIX

“…It uses a template based design where Templates Records carry the meta information and Data Sets the data itself. To adapt this protocol to the requirements of WSNs several modifications were essential and implemented in the so called Compressed IPFIX protocol as described in detail in [5]. The advantages of Compressed IPFIX protocol are: (1) a simple implementation, (2) use of less run-time-memory, (3) a simple data transmission and (4) transmission amount is reduced.…”
