When several sensor nodes work together, they form a wireless sensor network. The network constituted from these nodes is energy constrained as it is operated by the battery, memory constrained, and limited with processing speed. So, the routing protocol needed for such type of network should be such that it can full fill the requirement of such type of network. According to the IETF working group RPL(routing protocol for low power and lossy network) `is the best reliable and efficient protocol for wireless sensor networks.. This paper presents how the topology and network size affect the performance metric of RPL. . This paper represents the comparative analysis among Random, Linear, Ring, and Tree topologies based on performance metrics. So that the overall design of the network can be improved. The Cooja simulator is used to analyze the result, and it is found that random topology provides better results in terms of packet delivery ratio. In Linear topology, power consumption increases with network size. Rt-metric remains almost identical for the 10, 15, and 20-node networks.
