On Reliability Modeling in Wireless Sensor Networks-A Review

Free registration required

Executive Summary

This paper presents a survey on existing reliability models in Wireless Sensor Networks (WSNs). Most of the existing mechanisms employ retransmissions, ignoring redundancy schemes and moreover no attempt has been made for biologically inspired WSNs. This paper proposes a biologically inspired wireless sensor network model where sensor nodes are intelligent enough to recall the desired information despite of corrupted information sensed. The authors finally pointed out some of the future research directions and challenges ahead to improve the reliability in WSNs.
