Abstract:
Data availability in mobile information systems is lower than in traditional information systems due to its limitations of wireless communication such as low bandwidth, instability, and easy disconnection. Cooperative data caching is an attractive approach related to this problem because it allows sharing and coordinating the cached data among multiple mobile users in the network. So it can improve the performance of the system and the accessibility of data items. However, if we do not have a good cooperative caching approach then the cache hit ratio and response time may become ineffective. In this paper, we propose an efficient approach for cooperative caching in mobile information systems namely MIX-GROUP. We evaluate and demonstrate the experimental results on datasets by using NS2 simulator. MIX-GROUP is also proved the effectiveness by comparing it with the existing other approaches such as COCA and GROUPCACHING. The experimental results present that MIX-GROUP is more effecti
ve than those other approaches.
