Adaptive cache validation for mobile file systems

The uneven advancement in computing hardware components has restricted the development of mobile computing technology. Key components like bandwidth and battery life have only improved slightly over the last decade. Compounding this problem, systems are failing to address these constraints, focusing on cache consistency rather than accessibility. We propose a system that refocuses the design methodology towards file accessibility by offering a means of cache validation while disconnected. By using file information in the form of a file map stored locally, the likely status of a file can be determined. Thus the system can decide on an appropriate course of action without the associated cost of full validation of files. By offering a secondary means of validation, resources can be utilised more efficiently by directing tasks to processors rather than bandwidth.
