Abstract: The emergence of new mobile and wireless networks, with novel capabilities, offers opportunities to widen traditional internet-based applications. In this paper, we focus on a famous and widely used e-commerce application: auctions, and propose their deployment over ad hoc networks. Actually, we specify here this auction model while assuring identified crucial requirements: security and fairness. Security services are provided through threshold cryptography mechanisms whereas fairness is provided through rounds duration calculation. We prove that such a novel mobile commerce application presents advantages with regard to conventional economic models. Evaluations present optimistic results promising a realisable deployment of our auction model.

Keywords: mobile commerce; m-commerce; auctions; ad hoc networks; threshold cryptography; security; fairness; electronic business; wireless networks; mobile networks; e-commerce; electronic commerce; e-business; auction models.
