In wireless sensor networks, the necessity of reprogramming becomes more and more important for variety of purposes. However, the reprogramming produces a large amount of data and causes large energy consumption and interference. In this Letter, we propose an energy‐efficient reprogramming scheme with Raptor code by using transmission power control. By selecting proper relay nodes, relay nodes’ transmission power and Raptor code overhead, the proposed scheme minimises energy consumption while guaranteeing reliable transmission. This is verified by comparing it with conventional schemes.
