Abstract: Any network should have the capacity to operate in harsh environments despite of the constraints taken in WSNs. Multipath, tree, cluster and hybrid topologies are the collection schemes fail to provide a mobility, traffic and end-end connection. In earlier existing system like CIDT, the cluster head will be selected randomly because of it end-to-end delay, no of live nodes ,no of alive nodes, no of hops will more, in order to overcome this, a Velocity Energy-efficient and Link-aware Cluster-Tree (VELCT) scheme is proposed for the data collection in wireless sensor networks. End-to-end connection, delay, traffic coverage distance, mobility and residual energy can be controlled by the proposed VELCT scheme. Based on the cluster head location, the VELCT builds the Data Collection Tree (DCN). The DCN node doesn’t take part in sensing, however, it simply receives the data packet from the cluster head and delivers it to the destination. By using DCN node, the proposed VELCT scheme reduces the energy exploitation, reduces the end-to-end delay, number of dead nodes traffic, number of hops and residual energy of the nodes will be more in cluster head in WSNs. The main aim of VELCT algorithm is to build a simple tree structure, thereby reducing the energy consumption of the cluster head and avoids frequent cluster formation.
