Proactive management of large buildings requires continuous and real-time performance monitoring. Wireless Sensor Network (WSN) can be an efficient and flexible solution to provide this sort of large building monitoring. The aim of this paper is to implement a theoretical platform for a random WSN for monitoring applications in an irregular shape large building. The main WSN design objective is to achieve desirable coverage and accuracy while maintaining quality of service, cost, reliability, and scalability at acceptable levels. A major issue of concern is the connectivity of WSN, this is particularly important in sensor networks, where achieving a common application objective may require communication among all the nodes. Cooja is a flexible Java-based network simulator designed to model and simulate WSNs. Cooja is used in this paper to implement a random WSN for monitoring applications for the Sacred Mosque situated in Mecca. The area used for simulation is the second floor of the building. The simulation model consists of one stationary base station and a number of wireless motes that varies from 10 to 50 motes. In each group of simulation the transmission range varied from 20m to 100m with a step of 20m making a total of 25 simulation runs. Energy levels, network lifetime and delay are metrics taken into consideration in these experiments. The output of the experiments can be used to obtain an optimal solution for given operational conditions.
