Comparison of Cooperative Caching Strategies in Mobile Ad-Hoc Network (MANET)

A mobile ad-hoc network (MANET) is a self-configuring network of mobile nodes. MANETs are hindred by intermittent network connections, restricted power supplies, and limited computing resources. These restrictions raise several new challenges for data access applications with the respect to data availability and access efficiency. Data caching addresses these challenges in MANETs to improve the efficiency of information access. Cooperative caching improves system performance because it allows sharing and coordination of cached data among multiple mobile users in the network. This paper aims to classify and compare existing cooperative caching strategies for MANETs based on their performance metrics such as query latency and cache hit ratio.
