Study on 6LoWPAN Routing Protocols with SD aspects in IoT

6LoWPAN is a somewhat contorted acronym that combines the latest version of the Internet Protocol (IPv6) and Low-power Wireless Personal Area Networks (LoWPAN). 6LoWPAN, which, allows the smallest devices with limited processing ability to transmit information wirelessly using an internet protocol. 6LoWPAN faces problem with routing for research, still it has encapsulated a new routing header in the packet of 6LoWPAN and has been examined thoroughly. In desireness of achieving header compression, fragmentation and reassembly of IP packets one more layer was being introduced on top of MAC Layer and that was the adaptation layer. In this paper, different versions of 6LoWPAN protocol stack currently available is going to be discussed. 6LoWPAN have vital types of routing protocols which includes protocols like the simplified version Ad-Hoc On-Demand Distance Vector (AODV) such as Dynamic MANET On-demand for 6LoWPAN (DYMO-low) and Low On-demand Distance Vector Routing Protocol (LOAD). It also has Hierarchical routing (HiLow), which is been used to enhance the network scalability in 6LoWPAN. The contrast of routing protocols has been measured based on diversified matrices like memory usage, energy utilization, mobility of nodes, scalability in infrastructure, an RERR message, routing delay, a Hello message, and local repair. In this paper, we have presented the classification of routing algorithms of 6LoWPAN, on the different set of routing parameter for evaluation purpose. It was figured out from the result that the routing protocol has its own pros and cons depending upon the usage environment of the application.
