In Wireless Sensor Networks, several algorithms are used to perform different functionality, e.g. routing or clock synchronization. Each algorithm is intended for specific network characteristics and user requirements. But the acutal characteristics and requirements may change during system runtime. TinyCubus and particularly its Tiny Data Managment Framework use adaptation to solve this problem.

In this paper, we first explain the centralized adaptation process. Then, we examine how this can be done localized in the network. Since coordination between local adaptation decisions is found to be necessary, metrics for this coordination and their dependencies are shown.
