Environmental Monitoring Aware Routing in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) are designed for many monitoring and surveillance tasks. A typical scenario category is the use of WSNs for disaster detection in environmental scenarios. In disasters such as forest fires, volcano outbreaks or flood disasters, the monitored events have the potential to destroy the sensor devices themselves. This has implications for the network lifetime, performance and robustness. While a fairly large body of work addressing routing in WSNs exists, little attention has been paid to the aspect of node failures caused by the sensed phenomenon itself. This contribution presents a routing method that is aware of the node's destruction threat and adapts the routes accordingly, before node failure results in broken routes, delay and power consuming route re-discovery. The performance of the presented routing scheme is evaluated and compared to AODV based routing in the same scenario.

Environmental monitoring aware routing: making environmental sensor networks more robust

“…This means there are less successful transmissions in the OLSR scenario. Similar observations were made for AODV (see [14]). The reason for these problems even in the case of a static network is that neither AODV nor OLSR use context values such as the RSSI values.…”

Wireless Sensor Systems for Space and Extreme Environments: A Review

“…Another good example of cooperative technique directly associated with SEE is proposed by Wenning et al [29] with the environmental monitoring aware (EMA) protocol which takes into account the realistic fact that a deployment of a WSN in extreme conditions such as forest fire scenarios which can destroy the sensors devices in any moment due to the fire. This fact has direct implications for the network lifetime, performance and robustness.…”

Context-aware monitoring model using fuzzy logic for Wireless Sensor Networks in logistics

“…A lot of research on context-awareness has focused on two main fields: routing and applications. Environmental Monitoring Aware Routing [10] propose a multiplicative combination of environmental conditions and other context criteria for routing, which can be useful in disaster scenarios such as forest fires. In [11] [12], contextaware models based on programmable rules are mentioned to target the smart monitoring in logistics systems.…”
