Abstract

We describe a software framework for prescribing the trajectory path of a mobile sink in a wireless sensor network under an extensible set of optimization criteria. The framework relies on an integrated mobility manager that continuously advises the sink using application-specific network statistics. We focus on a reference implementation for TinyOS. Through extensive physical experimentation, we show that the mobility manager significantly improves network performance under a range of optimization scenarios.
