Abstract:
Data caching can remarkably improve the
efficiency of information access in a wireless ad hoc
network by reducing the access latency and bandwidth
usage. The cache placement problem minimizes total data
access cost in ad hoc networks with multiple data items.
The ad hoc networks are multi hop networks without a
central base station and are resource constrained in terms
of channel bandwidth and battery power. By data caching
the communication cost can be reduced in terms of
bandwidth as well as battery energy. As the network node
has limited memory the problem of cache placement is a
vital issue. This paper attempts to study the existing
cooperative caching techniques and their suitability in
mobile ad hoc networks.
Description:
Data Science & Engineering (ICDSE), 2012 International Conference on
Data caching is an attractive solution for reducing bandwidth demands and
network latency in mobile ad hoc networks. Deploying caches in mobile nodes can reduce
the overall traf c considerably. Cache hits eliminate the need to contact the data source
frequently, which avoids additional network overhead. In this paper we propose a data
discovery and cache management policy for cooperative caching, which reduces the power
usage, caching overhead and delay by reducing the number of control messages flooded into the network .A cache discovery process based on position cordinates of neighboring nodes is developed for this .The stimulstion results gives a promising result based on the metrics of the studies.
