Toward Interoperable Publish/Subscribe Communication between Wireless Sensor Networks and Access Networks

Traditional wireless sensor networks (WSNs) often do not consider interoperability between WSNs and access networks. To address the issue, this paper investigates interoperable publish/subscribe communication in WSNs. The proposed middleware, called TinyDDS, provides two types of interoperability, programming language interoperability and protocol interoperability, by customizing standard data types, data representation and session protocol. Evaluation results show that TinyDDS simplifies the development of publish/subscribe applications and it is implemented efficient in memory footprint and power consumption.
