Abstract
One of the fundamental purpose of sensing information is to immediately respond to any anomalies. In order to make an accurate and cognizant decision, there is a great need for a fault-tolerant wireless sensor network. In this paper, we evaluate two categories of dual-homed routing for providing fault-tolerance in wireless sensor networks, namely dedicated dual-homed routing and shared dual-homed routing. We investigate two dedicated dual-homed routing techniques, namely 1+1 dual-homed routing and 1:1 dual-homed routing. We also develop shared dual-homed routing techniques, namely 1:2 dual-homed routing and 1:4 dual-homed routing. This paper investigates each technique's capability for providing fault-tolerance and its performance in terms of network lifetime, packet loss probability, end-to-end packet delay, and average throughput. Such an investigation will provide a comprehensive understanding about each proposed fault-tolerant technique. This will provide valuable insight for providing grade-of-protection in multi-layer wireless sensor networks by applying different techniques at different layers. ©2008 IEEE.
