In this paper,the concepts,system structure,feature and the application areas of Wireless sensor network are introduced firstly.Then analyzed several key technologies of discount wedding dresses ,Meanwhile, many typical routing protocols are analyzed lace wedding dresses and evaluated overall.Based on the study above,we present a Hop Count-based Uneven Clustering topology control protocol(HCUC).Used the node hops to replace the node location cheap wedding gown dresses information,not only saved the energy cost by GSP positioning device but also expanded the cheap evening dresses applied scope of the network.The algorithm based on network coverage and the node's residual energy to select the cluster heads,making the number of cluster heads in accord with the 12hot cheap prom dresses optimal number of cluster heads and ensuring the quality of the cluster sell discount wedding dresses heads.Because the "multi to signal"communications feature of WSN,we chooseing cluster's radius along with the distance between the base station and nodes to reduce the influence of network discount wedding dresses performance initiative caused by "plus size wedding dresses".Simulating the HCUC protocol by NS2,the results show that the Hop Count-based Uneven Clustering topology control protocol(HCUC) can distributed the energy consumption between nodes more efficient,increased the network survival time and network throughout.
