The reliability of data delivery is a major concern in Low power Lossy Networks as they are deployed of devices of low energy, processing power and memory. The limitations of these devices leads to the dynamicity of the network.RPL is the routing protocol developed for these networks by the ROLL, working group of IETF. RPL is based on Destination Oriented Direct Acyclic Graph (DODAG). DODAGs have more than one path to the destination unlike the normal tree structure. Mac protocol supports the routing protocol to discover paths to the destinations using the link matrices. In our paper, we are comparing the three protocols: SBMAC, RBMAC and a RANDOM protocol on DODAG in terms of performance: drop rate and throughput. SBMAC follows the usual procedure of forwarding data packets depending on the routing table stored within the nodes. RBMAC forwards data packets to the nearby nodes and these nodes are then subjected to a competition to determine the next packet forwarding node. In random method, same procedure of forwarding data packets to the nearby nodes happens, but a random node will be chosen to forward the data packet.
