A Hierarchical Two-Tier Information Management Architecture for Mobile Ad-Hoc Grid Environments

A novel management layer architecture for mobile grid environments and ad-hoc networks is presented. This paper addresses a key challenge in dynamic mobile environments with a high degree of fluctuation in the hardware infrastructure: how to store information persistently and at the same time efficiently. Most currently available approaches are based on replication strategies. These strategies achieve persistency even in highly dynamic environments, but have to pay a high price for achieving redundancy. Our proposed architecture is based on the adaptation of fault-tolerant data distribution strategies utilizing erasure codes, such as RAID or Reed-Solomon, and thus combines persistency with high storage efficiency.
