Low powered hardware? You can give it more power. Why should security be sacrificed at all by IoT devices just to make them cheaper? Make them secure in the first place, point. With today's speed, I'd go with a traditional Feistel cipher with moderately high security margins any time. It's annoying that NIST approves standards with very low security margins - AES is an example of an algorithm with unnecessary low security margins, for instance. Speck and Simon are even worse in that respect.
