Abstract

The cross between mobile ad hoc networks (MANETs) and peer to peer (P2P) systems raises interesting capabilities to explore the deployment of various applications. This paper presents a new possibility to bring a mobile commerce application into P2P way. We propose a communication architecture called WAHS (Wireless Auction Handling System) and a communication protocol named BSAP-Protocol (Buyer/Seller Auction Peer) that governs interactions between BSAPs during a P2P auction process. Although tests and simulations give us an excellent overview of the protocol behaviour, the formal verification is needed to prove the correctness of a system. We formally specify and verify the properties of our proposal by the use of PROMELA/SPIN model checker. We implemented P2P auctions over MANETs functionalities' and give the first simulation results that show improvements in comparison to a previously published work.
