Routing methods on wireless network topology face unstable packet delivery and low resources, so many possibilities when reconstructing its topology has been neglected. This caused huge traffic at nodes on topology’s best links, furthermore even those good nodes’ electricity consumption tear down too soon. Recently, these problems are gradually improving, thus this technical enhancement brought IoT into smart-home technology. However, RPL (Routing Protocols for Low) is still not recommended for them since its traffic burst makes its link reliability extremely poor.
