We propose an analytical model to formally define the lifetime of Wireless Sensor Networks by considering various input factors including remaining energy, link quality, and location of the sensor nodes in the network. The model derives an expression for lifetime estimation on the basis of distribution of sensor nodes in the deployment area. The proposed model can be used to evaluate the performance of any routing protocol. We validate the model by means of simulation and show that the analytical outcomes are close to the experimental results.
