摘要
In this work, performance evaluation of LEACH and LEACH-C protocols based on NS2 is depicted, which helps to reveal the regularity how performances of these two routing protocols change with the sink locations. For a more accurate description of this regularity, two novel concepts are proposed, i.e., Sensor Node Distribution Gravity and Distance Metric between sink and Gravity. Simulation results show that a distance threshold area, which is a key factor for choosing between LEACH and LEACH-C protocols, can be achieved.
