Crowdsourcing: Dynamic Data Management in Mobile P2P Networks

For realizing such crowdsourcing-related M-P2P applications, dynamic data management becomes a necessity to improve data availability, given the mobility and fragile wireless connections that connect resource-constrained mobile devices. Moreover, unlike in the case of traditional environments such as clusters, free-riding is a major issue for M-P2P environments, thereby implying that economic models may play a better role in incentivizing peers to collaborate for data discovery and management. Furthermore, traditional methods of data management in mobile environments generally consider only single-hop client-server communication. On the other hand,in M-P2P networks, the network communication is multihop and mobile devices can collect real-time data. Finally, privacy issues need to be addressed effectively to prevent location-based service providers from misusing users´ location information.
