MSE-RPL: Mobility Support Enhancement in RPL for IoT Mobile Applications

Due to the expansion of IoT applications which causes generation a massive amount data, data routing is one most important challenges in these networks. The Routing Protocol for Low-power and Lossy Networks (RPL) was developed cope with lossy network constraints, play significant role Although involve mobility topology change that makes support substantial need prevent disconnection nodes loss, RPL designed static This article proposes method called MSE as an extension RPL. supports all except root node, it provides seamless connection during mobility. It also manages situation when physical obstacle settles between two paired dynamic environment. To this end, uses trickle timer different ranges, neighbor link quality table, function select best parent case mobility, confidence, critical zones, blacklist. Simulations multiple scenarios indicate MSE, despite causing slight increase signaling cost power consumption, significantly reduces hand-off delay, increases Packet Delivery Ratio, number lost packets, outperforms both reactive mRPL proactive protocol regarding
