Resilient and Secure File Dispersal in a Mobile P2P System

Khalid Ashraf, Rachid Anane, Nick Blundell
2011 2011 IEEE Workshops of International Conference on Advanced Information Networking and Applications  
This paper presents an approach to resilient file management and network storage through the design and implementation of a file dispersal system for a mobile P2P network, based on distributed hash tables  ...  The convergence of mobile networks and P2P systems has led to the deployment of a range of schemes for file storage over a network.  ...  Hash key distribution The hashing function has to be consistent and the hash key space generation should be equally distributed so that the keys do not map onto only one subset of the peers.  ...
