Investigating and Comparing Different Parameters to Select Strategies for Subscribing Sensors in Sensor Cloud Infrastructures

Wireless sensor networks (WSNs) have been designed and utilized in a variety of industrial, controlling, military and biological applications. The WSN is a system which consists of small wireless nodes which have been distributed on an application program and is characterized by energy limitations, cost and maintenance. The ability to create and produce reliable and flexible WSNs so that they can be used in various applications is of high significance. These networks are aimed at supporting predefined software services and since there are close ties between network and application programs, the capability of using sensor data will be limited. For enhancing the capability of WSNs, sensor-cloud infrastructure has been proposed. Indeed, sensor-cloud infrastructures were intended to be used as free and flexible platforms for obtaining, storing, using and subscribe data received from heterogeneous sensors. In this paper, an attempt was made to investigate and compare the strategies of subscribe sensors in sensor-cloud infrastructure. The researchers attempted to focus on the merits and demerits of the strategies so as to identify and learn their proper applications and utilizations in different situations. When the issues and problems are examined in the context of sensor-cloud system, the attraction of services (reliability, flexibility, message communications, QOS, etc.) for the final users will be increasingly high.
