Locality and Interest Awareness for Wireless Sensor Networks (LIASensor)∗

Abstract. Wireless Sensor Networks (WSN) consist in spatially distributed set of autonomous sensors along an area to be monitored. Such WSNs can be used both in military and civilian industry. Whereas in the military field, WSNs are used to monitor areas, that otherwise could not be possible to monitor, in civilian industry their usage covers various fields, such as health, farming, and environmental monitoring. WSNs can monitor vast extensions; however, there are limitations regarding their usage, being that energy consumption is the biggest problem. Power consumption is directly related with communication distance and message’s length. This work presents Location and Interest Awareness for WSNs (LIASensor), a WSN architec-ture for environmental monitoring. LIASensor reduces the network traffic through interest and locality awareness techniques thereby increasing the whole network lifetime. LIASensor was implemented and simulated in Castalia Simulator with promising results
