A tree-based Wireless Sensor Network (WSN) is a collection of sensors nodes, such as sink is the root of tree and leaves are the nodes. Data in such a topology flows from sensor nodes (leaves) to the sink (root) node of the tree. Collection of data from a set of sensors to an intermediate parent (sink) in a tree network is known as converge-casting. The delivery time and the data rate are application specific. As an example, in oil and gas refineries the sensor equipment and controllers need to collect data from all the sensors within a specific deadline for any kind of leakage or failures. Whereas applications like weather forecasting, under-water observations needs continuous and quick data delivery for analysis, for longer periods.
