WSN's modeling for a smart building application

Recently, wireless sensor networks are more and more used in smart building applications, due to their capability to collect data on all phenomena that happens in the building. The most important problem related to this kind of networks, is the limited lifetime of nodes, caused by their finite embedded source of energy (batteries). In order to reduce the impact of this problem, proper node model must be defined. In this work, we propose a behavior modeling of a sensor node. We evaluate the performance of our model and show the impact of the number of nodes and their placement on the maintenance cost of network. Presented results can provide guidelines for real sensor network deployment.
