Networks of small devices, such as environmental sensors, introduce a number of new challenges for traditional protocols and approaches. In particular, the extreme resource constraints characteristic of these devices forcethe engineering of device and application-specific optimizations in order to reduce complexity. By offloadingsome, if not most, of the complexity out of the small device and into the network, we simplify the design of individual devices, and may make otherwise infeasible applications possible. In this paper, we look specifically atthe problem of global mobility, and its associated protocolMobile IP (MIP). We introduce the mobility gatewaywhich performs MIP processing on behalf of registered devices. The mobility gateway provides an interface betweenthe optimized world of small devices and the larger Internet. Through simulation, we investigate the potential savings offered by this technique in terms of bandwidthand power. In a sample scenario, we find the total number of bytes transmitted over the wireless channel reducedby as much as 70%, and the battery life of the device extended by more than 100 hours.
