An Improved Data Mules Scheme Based on Controlled Working Area and Designed Trajectory
Under the traditional data Mules scheme in Wireless Sensor Networks,nodes cannot send the data until the Mules move nearby,which leads to longer data delay.To overcome this shortcoming,this paper improve the data Under the traditional data Mules scheme in Wireless Sensor Networks,nodes cannot send the data until the Mules move nearby,which leads to longer data delay.To overcome this shortcoming,this paper improve the data Mules through changing the working area of the Mules and designing its track.According to the mathematical analysis,we can find that reducing the working area of the Mules and its overlapped part can significantly reduced data delay and enhance the equity among sensor nodes.On the basis of this conclusion,a novel thinking and several recommendatory schemes are proposed.The simulation result shows that the new algorithms are significantly superior to traditional one in the aspects of data delay and nodes equity.
