英文摘要：

Well-designed network topology control method can reduce energy consumption and achieve efficient use of energy networks.The evolution rules of the wireless sensor network system topology are established,which are on the basis of two-dimensional cellular automata and consider nodes ＇ random distribution and the work/sleep/disable tri-state.The best control parameters of the evolution rules have been studied in setting the initial conditions,and simulation using those parameters shows that optimized cellular automata based network topology control extends the network life in ensuring coverage and connectivity.
