A Review of Cooperative Cache Management Techniques in MANETs

چکیده
Caching of frequently accessed data in ad hoc networks is a potential technique that can improve the data access, performance and availability. A cooperative cache-based data access framework lets mobile node cache the data or the path to the data to reduce query delays and improve data accessibility. Due to mobility and resource constraints of ad hoc networks, cooperative caching techniques designed for wired network may not be applicable to ad hoc networks. The objective of cooperative caching is to improve data availability and access efficiency by collaborating local resources of mobile devices. This paper reviews the various cooperative cache management techniques in the mobile ad-hoc networks.

Cache Discovery Policies of MANET
In situations where establishing a network infrastructure is impossible, Ad-hoc networks are considered particularly important. Most of the previous research in Ad-hoc networks concentrated on the development and enhancement of dynamic routing protocols, which could efficiently discover routes between two communicating nodes. Although routing strategies is an important topic in MANETs, other to...
متن کاملImproving on-demand data access efficiency in MANETs with cooperative caching
Mobile Ad Hoc Networks (MANETs) provide an attractive solution for networking in the situations where network infrastructure or service subscription is not available. Its usage can further be extended by enabling communications with external networks such as Internet or cellular networks through gateways. However, data access applications in MANETs suffer from dynamic network connections and re...
متن کاملCooperative Caching in Mobile Ad Hoc Networks Through Clustering
Constrained communication environment in mobile ad hoc networks (MANETs) due to insufficient wireless bandwidth and limited battery energy makes data retrieval a challenging problem. Due to frequent network disconnections in MANETs data availability is lower than traditional wired networks. Caching of frequently accessed data in such environment is a potential technique that can improve the dat...
متن کاملCooperative Cache Replacement Policy for MANETs
Mobile Adhoc Networks (MANETs) are autonomously structured multi-hop wireless links in peer to peer fashion without aid of any infrastructure network. In MANETs network topology is dynamic, as nodes are mobile. Due to this dynamic topology and multi-hop environment data availability in MANETs is low. Caching of frequently accessed data in ad hoc networks is a potential technique that can improv...
متن کاملA Selective Push Algorithm for Cooperative Cache Consistency Maintenance over MANETs
Cooperative caching is an important technique to support efficient data dissemination and sharing in Mobile Ad hoc Networks (MANETs). In order to ensure valid data access, the cache consistency must be maintained properly. Many existing cache consistency maintenance algorithms are stateless, in which the data source node is unaware of the cache status at each caching node. Even though stateless...
