This paper proposes a programmable routing framework that promotes the adaptivity in routing services for sensor networks. This framework includes a universal routing service and an automatic deployment service. The universal routing service allows the introduction of different services through its tunable parameters and programmable components. The deployment service completes the configuration of the universal routing service throughout a sensor network in an automatic and energy-efficient way. With this deployment service, a self-configuring ability is realized for sensor routing services. With the changeable parameters and programmable components of the universal routing service, the self-optimizing as well as other autonomic abilities can be explored in an experimental sensor network conforming to the proposed framework.
