On selecting a reliable topology in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have a wide range of applications including smart home and environmental monitoring systems. Sensors in such systems gather and propagate critical information to sinks (data collectors). Reliability is a crucial issue in these networks but the wireless medium is subject to interference and noise that can disrupt transmissions. Thus we design a reliable routing topology construction framework for WSNs and evaluate the proposed reliable topologies´ performance. We observe that there are tradeoffs of reliability, energy consumption and path properties that applications can take advantage of.
