Abstract: Broadband wireless services, including group-oriented mobile commerce services, are receiving a significant interest among researchers, developers, wireless service providers and users. In this paper, we focus on evaluating the network support for group-oriented transactions using simulation modelling techniques. Our results show that the transaction delays are governed by user connectivity/dis-connectivity ratio and average disconnection duration, while the transaction blocking is governed primarily by the average duration of disconnection. It is also shown that for multi-parametric cases, increased application flexibility can compensate for the negative impact of increased or more frequent user disconnections.
