Although Russia can also launch the required number of satellites, the entire GLONASS cluster will not be equally effective as GPS satellites, and will not match their standards in the near future.

即使俄罗斯发射了足够数量的卫星，GLONASS系统也无法像GPS系统一样被有效的使用，而且在短时间内也无法达到GPS卫星的标准。

Theoretical analysis and simulation results show that the proposed algorithm can effectively balance the number of nodes in each cluster, thus prolonging the effective lifetime of WSN.

理论分析和仿真结果证明，通过该方法进行分簇，可以有效均衡各个簇中的节点数，从而延长网络有效寿命。
