摘要:

针对低功耗有损网络(low-power and lossy network,LLN)的节点移动问题,提出基于博弈论自适应调整传输速率的移动RPL路由(GT-mRPL)。GT-mRPL路由通过博弈论传输速率,进而获取高的数据分组传递率和吞吐量。在移动环境中,将节点竞争发送数据过程设计成一个游戏。将通过增加传输率所获取的增益(效用函数)与因节点移动而产生的成本(移动函数)的比值看成收益函数。同时,考虑能耗对收益函数的影响。仿真结果表明,在移动环境下,提出的GT-mRPL路由降低了数据分组丢失率,提高了吞吐量。

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.

Key words: low-power and lossy network, RPL, mobility, game theory,, payoff function
