Abstract:Maintaining data consistency between data cached by a mobile client and data residing in the data server is a major issue in a wireless mobile environment. In this paper, we propose a push-pull cache consistency (2P2C) mechanism, with the intention of increasing the rate of serving requestors with recent up-to-date information or data from the cache of the intermediate nodes that are exact replicas of the data present in the origin server. This is a hybrid scheme that does not rely entirely either on the server or on the mobile client for maintaining consistency. Here we employ a registration process. Based on the registration process, the proposed 2P2C mechanism follows both a serverbased consistency scheme and a client-based consistency scheme. Besides this, both the server and the cache nodes can legitimately accept client registrations. Hence, this 2P2C method highly decreases unnecessary communication overhead incurred in the network and thereby considerably reduces access latency.

“…This scheme uses a mix of flooding and hop-by-hop requests, organising nodes into cooperation zones. The authors of [3] propose a cooperative and adaptive caching system based on different types of nodes -caching nodes and query directories. The former are the nodes actually caching data received from external sources and the latter serve as registers of cached data locations, handling data requests.…”

“…Existing MANET data distribution solutions [2], [3], [4], [5] rely on nodes cooperatively caching data and distributing it among themselves. Coordinating nodes' behaviour in a highly dynamic and completely decentralised and distributed environment, without an external controller or a reference point is one of the greatest challenges presented upon MANET cooperative data distribution.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract-Ad hoc networks of mobile nodes can be used to extend or improve connectivity, and cooperative data distribution represents the basis of this approach. Cooperation in such networks can be improved by providing nodes with information on network dynamics and topology changes. This paper proposes a proactive approach to handling mobility-induced network topology changes. The approach uses signal strength trends to predict the future locations and connectivity between the network nodes. Our research is aimed towards the creation of an alternative topology in each node, where a node would keep other nodes suitability for cooperation in the data distribution. In this paper we present the initial algorithm and test the prediction method using a simulation. The algorithm is then applied in an experimental testbed where its performance was tested using real moving nodes executing a real data distribution process. The performance results show a significant improvement in terms of file transfer delay. Permanent repository link

Caching is an essential mechanism in mobile environment. Mobile node makes access dynamic changing data object to their server and to get the interested data to keep their own as local copies in the cache. If the server database is updated, the data cached in mobile client is invalidated and it becomes inconsistent between client and server. In this study we design the cluster based caching technique in mobile node, this technique improves data accessibility, reduces the query latency and easy to maintains cache consistency in mobile environment. Designed a Cluster head node in between the server and the client using agent technique. Cluster head is selected nearest to the center of the grid and full battery power among other nodes in the mobile environment. Simulation is done on NS2, result show that reduces update delay, reduces Query delay, high throughput, high energy level when compared with existing approaches Distributed Cache Invalidation Method (DCIM).
