Abstract :
In wireless sensor networks, the bandwidth and energy are limited, and some link failures may happen during data transmission. We propose a fault tolerant multipath transportation aided with channel coding and interleaver (MTACCI) scheme for wireless sensor networks. Simulation results show that this scheme works much better than the dual transportation scheme in static channel and diversity combining scheme in fading channel when link failures exist. Further analysis demonstrates that this scheme can solve the bandwidth and energy constraint problems, and makes wireless sensor networks survivable and resilient.
