Wireless sensor networks (WSNs) depend on sensor node input and communications to a sink via a single or multi-hop path. Environmental conditions such as radiation events can disrupt node function, creating transfaulty nodes, which lead to communication holes in the system and loss of information. The current project presents the Reliable and Efficient Data Acquisition in Stationary WSN in the presence of Transfaulty nodes (REDAST) method, to identify transfaulty nodes, which are temporarily removed from the system. Subsequently the nodes are either able to switch communication modes from RF to radiation-resistant Acoustic mode, or awaken neighboring unaffected sleep nodes to transmit collected data. This method will address the isolation of nodes due to temporary damage from an environmental event. Simulation results show that the REDAST method achieves better results than existing methods in terms of throughput, packet delivery ratio and average delay time.
