对于LEACH协议阈值修改进行的改进，基于剩余能量和平均能量的考虑，在此文件中将簇头数目设为4，可以取得较好的运行结果-the improvement on the threshold of leach with the consideration on remained energy

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 descr i
