Analysis of RPL routing protocol on topology control mechanism

In 6LoWPAN, RPL routing protocol is suggested by IETF standard to enhance the Quality of Service of data transfer that occurs between non-root node to root node. In this paper, the performance of RPL is analyzed in terms of Packet Delivery Ratio and Round Trip Time. The analysis is carried out to study the behavior of topology control strategy in 6LoWPAN. Hence, the analysis is executed on various topologies namely linear, manual, elliptical and random. The proposed work is simulated using Cooja in Contiki Operating System environment. From the simulation results, it is inferred that the performance of both PDR and RTT in the manual topology outperforms the other three topologies. The reason being that manual topology are well planned topology which takes into account the channel impairment at the time of deployment which decides the QoS of the nodes.
