Dynamic adjusting policies on minimum hop gradient field in MHR wireless sensor networks
Mingcai Zheng · Computer Engineering and Applications Journal · 2011
In order to adapt to the dynamic topology structure of wireless sensor networks and improve the reliability of data sinking,the minimum hop routing wireless sensor networks must adjust its minimum hop gradient field real time.Considering for energy conservation,every node can monitor the information of its gradient neighbors in real time and dynamically adjust its minimum hop count value,so the network's minimum hop gradient field is updated real time and at an ease rate. Theoretical analysis and simulation results show that the method is efficient when the change of network physical topology structure is small-scale and without mutation.
