Sensor networks are a sensing, computing and

communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. In this paper, we investigate

how the sensor network performs in the case when three events move with special movement path. We compare the simulation results for three cases: stationary, random and simple 4 path. We found that the goodput of random model has the best value among the three models when Tr < 1pps. The average packet loss of simple 4 point model is the lowest among the three models. The RE of stationary model, simple 4 point model and

random model has stable values. In case of random model, the RE is better than other models.
