Hierarchical Topology Structure Control of Wireless Sensor Nets

Under the condition of coverage and connectivity,the wireless sensor net topology control eliminates needless wireless commutation link among the nodes,and creates an efficient data transition network topology structure.Hierarchical topology structure control makes use of clusters organized algorithm,selecting some nodes as cluster nodes,forming a skeleton net to dispose and transmit data.Other non-skeleton net nodes can temporarily close communication module,and enter the dormancy state to save the energy.The improved GAF dummy geographical grid cluster algorithm and Top Disc algorithm are studied in the paper.
