PUMA: policy-based unified management architecture for wireless networking

This paper presents PUMA, a novel declarative constraint-solving architecture that achieves efficient policy-based adaptive routing and channel selection for wireless networks. PUMA is based on declarative networking , a database-inspired extensible infrastructure using query languages to specify behavior. In PUMA, users specify high-level declarative policies that dictate their channel selection constraints and routing protocol behavior. The runtime system generates the actual implementation that meets these specifications. Moreover, PUMA provides avenues to optimize across routing and channel selection policies. We have developed a prototype of PUMA that is extensively evaluated in simulations and on the ORBIT testbed.
