ReInForM: Reliable Information Forwarding Using Multiple Paths in Sensor Networks
Sensor networks are meant for sensing and disseminating information about the environment they sense. The criticality of a sensed phenomenon determines it’s importance to the end user. Hence data dissemination in a sensor network should be informationaware. Such information-awareness is essential firstly to disseminate critical information more reliably and secondly to consume network resources proportional to criticality of information. In this paper, we describe a protocol called ReInForM to support information awareness in sensor networks. Using ReInForM, data can be delivered at desired levels of reliability at proportional cost, in spite of the presence of significant channel errors. It uses the concept of dynamic packet state in context of sensor networks to control the number of paths required for the desired reliability using only local knowledge of channel error rates and does not require any prior computation or maintenance of these multiple paths. We also show that for ...
