In CT (Current Transformer), a sensor node is selected in the chain to act as a leader, and then the remaining sensor nodes can communicate with each other along the chain path. Excessive delay from distant nodes on the chain is the main demerit of this topology (i.e., data collection on the longer chain obtains larger time). This existing method have limitation such as delay, node failure, data redundancy and large amount of energy utilization, since it is using flooding, gossiping, direct communication, etc., to communicate between the nodes. It is the main drawback of this topology and not recommended to mobile WSNs (Wireless Sensor Networks).
