Abstract	This paper presents the design and implementation of PUMA, a declarative constraint-solving platform for policy-based rout-ing and channel selection in multi-radio wireless mesh net-works. In PUMA, users formulate channel selection policies as optimization goals and constraints that are concisely de-clared using the PawLog declarative language. To efficiently execute PawLog programs in a distributed setting, PUMA in-tegrates a high performance constraint solver with a declar-ative networking engine. We demonstrate the capabilities of PUMA in defining distributed protocols that cross-optimize across channel selection and routing. We have developed a prototype of the PUMA system that we extensively evalu-ated in simulations and on the ORBIT testbed. Our experi-mental results demonstrate that PUMA can flexibly and ef-ficiently implement a variety of centralized and distributed channel selection protocols that result in significantly higher throughput compared to single channel and identical channel assignment solutions. 1.
