Regardless of the application, the way that data and information are disseminated is an important aspect in Wireless Sensor Networks (WSNs). The wireless data dissemination protocol should often guarantee a
minimum reliability requirement. In this regard and to well-balance the energy and reliability, the more
important packets should be protected by more powerful error control codes than the less important ones.
This information-aware capability allows a system to deliver critical information with high reliability but
potentially at a higher resource cost. In this paper, we first find and evaluate the factors that may influence
the importance level of a packet and then design an error control approach by adaptively selecting codes for each individual links which experience long-term-fading and for each individual packet at run-time instead of applying network-wide settings prior to deployment. Moreover, we target the poor-explored chain-based topology that is of interest for many applications (e.g. monitoring bridge, tunnel, etc.). Simulation results
validate the superiority of our approach compared with a number of Reed-Solomon-based error control
