Mobile Ad hoc NETworks (MANETs) emerge as an e effective solution for networking Smartphones to enable wire-less communication when other alternatives such as cellular networks are not available, e.g. in rural areas. Available MANET routing protocols are either conservative (reactive protocols, e.g. AODV) to control overheads and so do not have any knowledge beyond neighboring nodes, or too expensive (proactive protocols, e.g. OLSR) on resources for Smartphone based MANET networks. Irrespective, all these protocols have limited protection against threats from malicious nodes in the vicinity.
