基于终端电能状态的网络接口开启间隔算法

Network Interface Activating Interval Algorithm Based on Terminal Battery State

针对动态开启间隔算法存在网络接口开启间隔次数过多及网络选择时间过长的问题,提出一种基于终端电能状态的网络接口开启间隔算法,将终端剩余电能状态β作为功耗代价的权重,使网络性能函数成为网络开启间隔的影响因子,对网络流量进行有效管理。仿真实验结果表明,在网络选择过程中,当终端移动速度不超过1.4m/s时,该算法具有较少的网络开启间隔次数和较短的网络选择时间。

Aiming at the problems that the interval number of network interface to open is too much and the network selection time is too long in dynamic activating interval algorithm, a network interface activating interval algorithm based on terminal battery state is proposed, which makes the terminal remaining battery state fl as weight of power consumption cost. The network performance function is made as the influence factor of network activation interval. The network flow is managed. Simulation experimental results show this algorithm has less interval number of network interface to open and short network selection time in process of network selection, when the terminal moving speed is less than 1.4 m/s.
