Abstract
The availability of multiple frequency channels on mod-
ern radios has provided a way to improve networking perfor-
mance. Nevertheless, current multi-channel protocols lack
the architectural consistency and flexibility to support a di-
verse set of applications. In this paper we argue that it is
necessary to integrate channel switching to the emerging
wireless sensor network architecture and propose a way to
decompose the problem into two reusable components: the
channel allocation component that is integrated with network
layer protocols and a shared channel synchronization com-
