The effectiveness and the efficiency of the Wireless Sensor Networks (WSNs) entirely depend on the data accumulation method. Numerous data accumulation methods like multipath, tree, chain, hybrid and cluster topologies are available in the past for accumulating data in WSNs. The subsisting data accumulation methods in the past don’t provide an assured reliable network from the perspective of movement of delay, speed, and connection time. A Link-aware and Velocity Energy-efficient Cluster-Tree (LAVECT) topology for accumulation of data in WSNs with the avail of special nodes called data accumulation node (DAN) constructs a tree, which is an optimal path to the sink, which would in turn efficiently resolve the coverage distance, energy exploitation, mobility of sensor nodes, delay in packet distribution, traffic in the network, intensity of the tree constructed and connection time problems. The discovered LAVECT scheme constructs the Data Accumulation Tree (DAT) predicated on the cluster head location in the network. It additionally maintains the cluster for a considerable duration, thus incrementing the connection time. Simulation results show that LAVECT provides better performance from the perspective of energy utilization by the nodes, throughput, delay, and network lifetime for mobile WSNs. Conclusively, Data security is provided to reach the sink.
