Improved fault‐tolerant optimal route reconstruction approach for energy consumed areas in wireless sensor networks

Abstract

Persistent sensing requires sensor nodes to keep functioning for a longer duration. Different amounts of incoming packets on some sensor nodes after deployment lead them to deplete their energy faster compared to other nodes without sending the information about their death to the sink node. It results in the formation of energy holes in the network and hence packet loss problem starts. In this study, this problem is overcome by prior notification to the sink about scarcity of resources by setting a dynamic threshold and also, packet delivery is sustained by using a fault tolerance strategy. Simulation analysis shows that proposed work is doing better in terms of packet delivery ratio and number of dead nodes. Also, network lifetime of the proposed work is found to be 73% of the total time duration while its competitor approach has network lifetime 64%.

Fuzzy Logic and Modified Butterfly Optimization with Efficient Fault Detection and Recovery Mechanisms for Secured Fault-Tolerant Routing in Wireless Sensor Networks

“…However, it considers only the loaded CH faults, while ignoring sink node failures. Maratha et al [24] developed an improved Fault-Tolerant Optimal Route Reconstruction (IFTORR) approach for increasing the lifetime of WSN through optimized routing. However, this method considered only the route failures, while ignoring both node and link failures.…”

Reliability on the Internet of Things with designing approach for exploratory analysis

“…Missteps in IoT gadgets and network connections have a significant impact here on the architecture of IoT networks as well as communications. IoT systems are becoming more potent as well as sophisticated because of developments in numerous IoTsupporting technologies (Maratha et al, 2020(Maratha et al, , 2021. However, when the components of system cooperate as well as interact more, new potentially unidentified dependencies arise.…”

Discrete Integrity Assuring Slice‐Based Secured Data Aggregation Scheme for Wireless Sensor Network (DIA‐SSDAS)

“…Hence, the data transmission which is the major cause of energy depletion in wireless sensor network attracted the attention of research. Efficient routing protocols [2][3][4] and mobility sinks are proposed to minimize the transmission. Sensor nodes usually deployed in dense lead to redundancy in the data being measured.…”
