The mobile-P2P paradigm is becoming increasingly popular. Existing mobile-P2P solutions largely do not consider economic incentive models for enticing peer participation without eliminating free-riders and for effectively handling mobile resource constraints such as energy.

We also present our perspectives on building ‘real’ mobile-P2P applications using economic models.
