Dynamic allocation of sensor nodes in wireless sensor networks hosting multiple applications

Wireless sensor networks (WSNs) hosting multiple applications are gaining popularity over WSNs dedicated to a single application. The applications hosted by the WSN often have various different characteristics. This research investigates the importance of using information about the characteristics of the applications and the state of the network while allocating the sensor nodes to requests for applications. A number of allocation algorithms are investigated. Results of simulation experiments demonstrate that the minimum energy level at the sensor nodes and lifetime of a WSN are effectively increased when using information about the applications and the state of the WSN and by performing dynamic allocation for every application request.
