| Popis: |
A distributed data sinking mechanism based on joint optimization,abbreviated DDSM,for periodic report wireless sensor networks is proposed,which integrates MAC layer and network layer.In this mechanism,a joint optimization algorithm is provided which connects the routing with the slot allocation.DDSM constructs an appropriate transmission schedule that avoids transmission collisions and choose the optimum routing path that achieves high levels of power conservation.Finally,experiments are performed to evaluate the performance of the proposed mechanism.Simulation results show that DDSM can reduce the energy consumption of nodes and provide longer network lifetime. |
