This paper presents the design and implementation of declarative policy-based adaptive MANET routing protocols. Our work builds upon declarative networking, a recent innovation for building extensible network architectures using declarative languages. We make the following contributions. First, we demonstrate that traditional MANET protocols can be expressed in a compact fashion as declarative networks. We validate these declarative protocols via an experimental study on the ORBIT wireless testbed and a cluster-based emulation environment. Second, we demonstrate that policy-driven adaptation can be specified in a generic set of declarative rule-based policies that dictate the dynamic selection of different protocols based on network conditions. Third, we conduct extensive evaluation results of declarative policy-based adaptation of MANET routing on the ORBIT wireless testbed and the cluster-based emulation environment. Our experimental results show that the specified policies enable MANETs to dynamically hybridize a variety of routing protocols to achieve a good tradeoff in bandwidth utilization and route quality.
