IMOTE2: Serious Computation at the Edge

While the majority of sensor network application research to date has focused on applications where the controlling processor need only be capable of handling simple communications and data primitives required for low rate sampling, comparatively few researchers have targeted the other end of the spectrum; applications where there is a significant advantage to performing data processing at the edge of the network. This paper describes Imote2, an advanced sensor network node that enables such usage models, and introduces several applications and scenarios where we have found such edge processing to be a significant advantage.
