This project aims to create an infrastructureless platform for information delivery using wireless ad hoc network to be used for disaster mitigation. For this purpose, we developed two modules. First, an information searching protocol to allow users to locate the information source and direct the request to this information source. This module can be visualized as a situation in which a victim is looking for medical help but he does not know where to send the request, so he needs this protocol to locate the medical team and direct the request to them. Second, a packet routing protocol for fast and reliable packet delivery. Considering the topology of wireless ad hoc network changes frequently, we introduced the concept of path and server diversity to deliver the information in this platform. The concept is similar to file-sharing in peer-to-peer network, in which a recipient may receive the same contents from multiple sources, but the implementation is different because a content server is not available in mobile ad hoc network. It allowed continuous collaboration with reputable researchers from Japan. The students had the opportunity to interact with reputable researchers from Japan. It provides motivation and initial work to tackle issues related to disaster mitigation, which is one of the main focuses of many countries.
