基于交互式斜率比较的数据包节能传输调度
摘要
为了节省无线传感器网络中的数据包传输耗能
提出交互式斜率比较(ISC)算法进行速率控制调度。该算法根据数据包到达和截止曲线
通过不断比较到达点和截止点对应的斜率
得出每个传输段及其速率。所提ISC算法在离线模式下可以实现最低能耗数据包传输
扩展到在线模式后
传输能耗也可以逼近最小值。考虑在1 s时间内传输500个包
所提方法在离线和在线模式下的能耗分别仅为传统方案的0.413%
0.483%。
Abstract
In order to save energy consumption of packet transmission in wireless sensor networks
an algorithm of interactive slope comparison( ISC) is proposed for rate-control scheduling. According to the packet arrival and deadline curves
and by comparing slopes corresponding to arrival and deadline points continuously
each transmission segment and its rate are obtained. In offline mode
the proposed ISC algorithm can achieve packet transmission with the minimal energy consumption; expanding in online mode
transmission energy consumption can also approach to the minimal value. Considering transmitting 500 packets within 1 s
the proposed method only consumes 0. 413 % and 0. 483 % energy of the traditional scheme in offline and online modes
respectively.
