Application background wireless sensor network (WSN) plays an important role in today's real world. The effectiveness of wireless sensor network purely depends on the data acquisition scheme. A large amount of data, such as multipath, chain, tree, cluster and hybrid topology collection plans, can be collected in the literature in wireless sensor networks. However, the existing data collection program fails to provide a reliable network in terms of mobility, traffic and end-to-end connectivity. The key technology is to design velct scheme to minimize & nbsp; energy development, reduce the end-to-end delay and the effective use of DCT of traffic cluster head in wireless sensor networks. &The strength of velct algorithm is to build a simple tree structure, so as to reduce the cluster energy consumption and avoid the formation of frequent industrial clusters.
