Self-sustained Routing for Event Diffusion in Wireless Sensor Networks

Abstract

Wireless sensor networks have the potential to become a scalable, low-cost and highly flexible tool for distributed monitoring and/or event recognition: Embedded devices that coordinate themselves via wireless communication to implement a common, distributed application are already seeing first industrial adaption in e.g. home automation, personal health or environmental monitoring. Despite of their valuable properties they put a high burden upon application development since critical issues such as a general resource scarcity, the unreliable communication medium and the management of distribution are often visible throughout the protocol stack to ensure efficient utilization.

In the demo, we will show how our middleware framework FACTS helps to alleviate problems in implementation of both system- and application-level code. Providing a rule-based, domain-specific language, FACTS is especially suited to express event-driven tasks. Therefore, we will showcase how to efficiently program a self-sustained routing protocol forwarding relevant events to dedicated sink nodes with only a handful of rules.
