A Fault Tolerant Topology Control Algorithm for Large-Scale Sensor Networks
Adelaide, Australia
December 03-December 06
ISBN: 0-7695-3049-4
In this paper, we present a Distributed Geography-based Fault Tolerant topology control algorithm (DGFT) for static large-scale wireless sensor networks. We introduce the scale-free characteristic of complex networks into the topology of large- scale wireless sensor networks to obtain robustness and time efficiency. DGFT enables wireless nodes to define the topology by neighbor relationship, based on certain initialized weights whose distribution follows a negative power law. We prove that the topology constructed under DGFT is strongly connected and bi- directional. Simulation studies show that the resulting topology has good network performance in terms of transmission delay and robustness. Keywords: wireless sensor networks; topology control; scale- free; transmission delay; robustness I.
