LCS-MANET: A mobile storage architecture with location centric storage algorithm in manets

Mobile networks, typically, Mobile Ad-hoc Networks (MANETs), bring a new opportunity for sharing data on mobile devices. To provide available data storage and sharing service, we propose a mobile storage architecture in MANET called LCS-MANET, in which the key algorithm is Location Centric Storage (LCS) algorithm. In LCS-MANET, the nodes are classified into two types: storage nodes and common nodes. We implement location centric data storage algorithm on storage nodes and also design the data replication algorithm upon them. In the evaluation, when nodes move slowly, the query success rate can reach 80% in LCS, and even when moving at the speed of 15m/s, the query success rate of LCS achieves over 30%. Evaluation results show good performance in the scenario of mobile networks and data availability.
