Wireless sensor network data description and encoding in heterogeneous building systems

摘要

This paper presents initial results and future directions for data description and payload encodings for heterogeneous networks in IP based building intelligence systems. The efficiency of several open standards for sensor data representation are evaluated along with a consideration of the complexity of implementation and suitability for use in development of 6lowPAN based intelligent building systems. A combination of a simplified generic XML schema for data description combined with Google Protobuffer encoding is suggested as the basis for further development of the architecture as this combines simple, platform independent implementation for developers with efficient compression and payload encoding for limited bandwidth 6lowPAN networks.
