Abstract :
Due to the fact that TTDD (Two-Tier Data Dissemination) could not adjust the grid structure according to the real time flux, we propose DGS, a Dynamic Grid Switch multi-sink data gathering mechanism which constructs grid based on the TTDD. DGS adds even driven mechanism to dynamically adapt to the whole network energy status. The frequency of grid switch is based on the power level of even status the energy mode. DGS also supports mobile sink conditions in such environment. Our results demonstrate that DGS could efficiently enhance the network life and achieve load balance even when nodes are mobile.
