Abstract
Wireless sensor networks suffer from some setbacks due to its ad-hoc nature of deployment and its node are prone to be defective due to several conditions like weather, environment where sensors are deployed etc. It also suffers from resource limitations, high failure rates and faults caused by the defective nature of wireless communication and the wireless sensor characteristics. This can lead to situations, where nodes are often interrupted during data transmission and blind spots occur in the network by isolating some of the devices. Hence reliability and availability is an important research area necessary to make wireless sensor networks more acceptable as a means of communication. In this paper, the issue of reliability will be addressed by designing and developing an improved fault-tolerance mechanism of Ad-hoc On-Demand Distance Vector (AODV) routing protocol for WSN called the IMproved FAult-Tolerant AODV (IMFAT-AODV) routing protocol. The proposed IMFAT-AODV routing protocol improves the reliability and robustness of the network by creating a backup path only when any three consecutive nodes on the main path of data delivery (data forwarding) has been traversed . This is an improved version over the enhanced fault tolerant AODV routing protocol where a backup route is created for every nodes in the network. Although it increases the overhead packet width, but simulations show that it is better when sensor nodes are not highly prone to error. When a node gets failure to transmit a data packet through the main path, it immediately utilizes its backup route to become a new main path for the transmission of next coming data packets when the fault flag on the IP packet is raised. This protocol reduces the number of dropped data packets and maintains the continuity of data packet transmission in presence of network faults. The simulation results prove that the proposed IMFAT-AODV routing protocol is better than the original ENFAT-AODV in terms of the reliability, throughput and fault-tolerant ability of the network for sensor nodes that are not highly prone to error.
