High-efficient RPL routing for analyzing mobility of nodes
Abstract
To deal with the mobility of nodes in low-power and lossy network(LLN),the adaptive transmission rate based game-theory mobile RPL (GT-mRPL) was proposed.GT-mRPL uses variable transmission rate-based game theory to achieve higher packet delivery ratio and better throughput.In a mobile environment,a game was designed for nodes competing to send data.The payoff function was defined to assess the profit gained from increasing data transmission rate (utility function) against the cost induced by the presence of mobile nodes (mobility function).Other factor was also taken into account in formulating the payoff function including the energy consumption.Simulation results show that in the presence of mobility,GT-mRPL reduces the packet lost ratio and improves the throughput.
