A Publish/Subscribe Middleware Cost in Wireless Sensor Networks

Electronic devices and sensor networks have witnessed great advancements. Consequently, their limited resources (CPU, memory, bandwidth, and power) are becoming suitable to accommodate some of the enterprise networks solutions. One possible and effective solution is Middleware technology that is able to provide several advantages such as simplifying applications development, portability, scalability, and Quality of Service (QoS). Recently, A publish/subscribe (pub/sub) middlew are in Wireless Sensor Network (WSN) has gained a lot of attention from both the industry and the academic communities. This paper provides a review to the state-of-the-art of some of these solutions. This paper also investigates the capabilities of these solutions and conducts a comparison study. In addition, a case study is carried out to estimate the cost of adding a middleware to a WSN. Furthermore, a study is performed to the middleware effect on the overall network performance.
