Enhancing Data Availability in MANETs with Cooperative Caching

Mobile Adhoc Networks (MANETs) are very popular solutions where network infrastructure installation is not possible. In MANETs, nodes are mobile, and due to this mobility, topology of the network changes rapidly. This dynamic topology reduces the data availability in MANETs. Cooperative caching provides an attractive solution for this problem. In this paper, a new cooperative caching algorithm, ProCoCa, is proposed. This algorithm is based on a proactive approach. Each node will be associated with a zone and the data of leaving node will be cached. The authors simulate the algorithm on OMNET++ simulator, and simulation results show that ProCoCa improves the data availability as well as overall performance of the network.
