In emergency and rescue operations MANETs can help to improve the efficiency of the collaborative work. The goal is to increase the availability of services and information through resource awareness. The work described in this paper, presents our approach towards prediction of current and future resources available on remote devices. Our resource prediction algorithm is based on information extracted from a node?s routing protocol. The advantage of this approach is that resource management is not intrusive, does not need location information, and can work with any given routing protocol. We are using simulations with different node mobility models, routing protocols and communication patterns, to analyze for how far into the future we can make valid predictions.
