Abstract

The higher demand for use of Wireless Sensor Technology, in the presence of complexities of various deployment environments, and application areas such as wireless multimedia sensor networks, call for the need to improve performance and availability of WSNs. This paper seeks to justify the need to model both performance and availability of WSNs together, parting from the current independent approaches and provides a systematic modelling approach for performability of WSNs. This has further been necessitated by positive research findings facilitating repair and replacement of faulty and dead sensor nodes and communication links. Two different analytical solution approaches are employed for performability modelling of a WSN cluster, and simulation results presented are in agreement with the analytical approximations. © 2013 Springer-Verlag.
