Code dissemination, which refers to the process of propagating a new code image to deployed sensor nodes through wireless links, is an essential service for wireless sensor networks.It must guarantee that every node in a network correctly receives a complete code image.Several methods have been developed for reliable and efficient code dissemination in wireless sensor networks.However, none of them considers the negative impact of environmental and unintentional wireless interference.In particular, all existing approaches will fail if severe interference exists in a single channel (e.g., control channel).To address this problem, we present an interference-resilient code dissemination system named IR-Seluge for wireless sensor networks.IR-Seluge has been implemented in nesC on TinyOS and evaluated through a substantial set of experiments in a wireless sensor testbed, which consists of 73 MicaZ motes.The experimental results indicate that IR-Seluge effectively and efficiently mitigates the problem of wireless interference.
