Sensor-DMAC: dynamic topology control for wireless sensor networks

摘要: We present sensor-DMAC (S-DMAC), a new mechanism for topology control in wireless sensor networks. A (connected) fraction of the network nodes is efficiently selected to perform operation while all other are switched an energy-conserving "sleep mode." Based on DMAC, clustering protocol enhanced with backbone formation, S-DMAC reduces minimum overhead associated node selection, formation and maintenance, thus increasing overall lifetime. Ns2-based simulations have been performed compare DMAC also GAF, recent solution These results show as more effective providing connected energy efficient routes data from collection point (sink).
