A general-purpose service-oriented middleware model for WSN

Wireless sensor networks (WSN) play an important role in many applications like healthcare, traffic monitoring, security, environmental and infrastructure monitoring. When designing these applications for different domains like healthcare, traffic management or military intelligence, people face a lot of challenges. Service-oriented architecture (SOA) is an emerging area in distributed computing that uses services as a software component to complete a task. Service-oriented middleware (SOM) is based on SOA and is very beneficial in helping to overcome WSN challenges. SOM provides different services to applications and the underlying network to reduce the complexity of the system. SOM helps in achieving interoperability and heterogeneity. In this paper we discuss some available SOM and highlight different services provided by these approaches. Also, a general purpose SOM is proposed that will fit with different types of applications from different domains.
