Designing an Effective Error Control Scheme for Real Time Wireless Sensor Networks (WSNs)
Abstract
Abstract Views: 83
Wireless Sensor Networks (WSNs) subsist on a network of a huge number of hubs distributed in unfavourable environments. They are used for habitat monitoring and to observe changes in them. These hubs are susceptible to faults such as energy exhaustion, hardware glitches, communication link errors, and malicious attacks, which may cause errors during message delivery. Typically, these systems are utilized to send and receive vital information in remote places. Thus, efficient error identification and correction is required in order to maintain the accuracy of the received messages. The aim of this study was to design a high speed reverse converter to devise effective error control codes. It used the Redundant Residue Number System (RRNS) to enhance the accuracy of messages delivered through real time WSNs. In order to attain a greater error correction ability, a reverse converter, based on Mixed Radix Conversion (MRC), was designed for the moduli set {2n+1-1, 2n, 2n-1}. In addition to this moduli set, an extra redundant moduli set {2n+1+3, 22n - 3} was also formulated for better error correction. For correction and identification of corrupted values in the original data, Maximum Likelihood Estimation (MLE) was used. The results revealed that the suggested moduli set offers low energy utilization and consistency of the received messages through real time WSNs.
