Sink节点自适应位置更新在无线传感器网络中节能的优化

Adaptive Location Updates for Mobile Sinks in Wireless Sensor Networks

在无线传感器网络中,移动Sink节点可用于平衡无线传感器网络节点的能量消耗,降低无线传感器网络中的能量消耗;但是,Sink节点频繁的位置更新又会导致传感器网络节点的能量消耗和数据流传输中的阻塞;提出了一种新的解决方案——自适应移动Sink节点的位置更新算法(ALURP),以解决此问题;当一个Sink节点移动时,它只需要在一定小范围空间中进行信息更新而不是以往的在整个网络中;理论分析和研究表明,这种设计方案会减少消耗在每个传感器节点上的能量,也缓解了无线传输数据流中的拥挤,可在大型无线传感网络中使用。

In wireless sensor networks,mobile receiver can be used to balance the wireless sensor network node energy consumption,mobile receiver sensor nodes need to inform them of the new location information.However,from the mobile receiver frequent location update will lead to the energy consumption of sensor network nodes and data streaming in the block.This paper presents a new solution-adaptive mobile receiver＇s location update to resolve this problem.When a receiver moves,it only needs a certain small-scale space for information transmission,rather than the past,and then the entire network.Theoretical analysis and simulation studies have shown that this design will reduce the consumption of each sensor node＇s energy,but also eased the wireless transmission of data streams in the crowded,can be used in large-scale wireless sensor networks.
