So as to guarantee the fairness of electronic transactions, users may require a NonRepudiation (NR) service in any type of network. However, most existing NR protocols cannot work properly in a Mobile Ad hoc Network (MANET) due to their characteristics (e.g. limited resources and lack of central authority). The design of the Probabilistic NonRepudiation Protocol (PNRP) is comparatively suitable for the nature of a MANET, but it still poses some QoS issues. This article points out the QoS issues which are caused by using PNRP in a MANET environment. These issues explain the difficult of performing PNRP in such an infrastructureless environment.
