Abstract: In spite of the extensive research on Wireless Sensor Networks (WSNs) in recent times, it still remains a challenging field of study due to the resource constraints in such networks. While packet-level network coding has been studied widely in the context of wireless networks for improving network throughput, its application for WSNs is limited due to the amount of resources (time, memory and energy) needed. In this paper, we propose an a protocol called FR Code that uses network coding for code dissemination, which is an important and periodic task in WSNs. The proposed protocol minimizes the number of transmissions for code dissemination, while disseminating the code updates reliably. At the same time, it consumes much lesser time and energy compared to dissemination using other network coding schemes. This results in better network lifetime and faster code dissemination. The benefits of the proposed protocol are proportional to the density of nodes in the network. Hence FR Code is most suitable for dense WSNs.
