Recent research has shown that using a mobile element to carry data mechanically in a wireless ad hoc network has many advantages over static multihop routing. These works can be broadly classified into two classes. The mobile element acts as a data sink collecting data being generated at the static nodes. This specifically applies to sensor networks. Alternately, the mobile element is used to route data from one part of the network to another. In this paper, we present a routing protocol, where data can travel wirelessly through multihop, or can be mechanically carried by the mobile element(s). The decision is made at runtime, depending on application requirements. Also, we investigate use of two types of mobile elements in our system: those whose motion can be predicted, and those whose motion can be controlled. For the controlled mobile elements, we propose and evaluate some scheduling heuristics.
