Smooth Resilient Service Provision in Large Heterogeneous Networks

Mobile crowd missions like multiplayer online games, disaster recovery, and mobile-assisted public gatherings gain ever more attention. They depend on highly distributed software which has to run smoothly and highly synchronous, while the underlying network – often a mix of mobile and stationary nodes – may expose Byzantine errors and malicious attacks. In our paper, we present a first solution to this challenge, emphasizing first response missions as an example. It combines support for Byzantine error correction, mobile code, smooth handover, and availability and performance improvements through replication and intelligent service placement. Finally, we point at further challenges that arise on the move towards a broader spectrum of mobile crowd missions
