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.

Abstract:
Cooperative caching in mobile ad hoc networks
aims at improving the efficiency of information access by
reducing access latency and bandwidth usage. Cache replacement
policy plays a vital role in improving the performance of a cache
in a mobile node since it has limited memory. In this paper we
propose a new key based cache replacement policy called E-LRU
for cooperative caching in ad hoc networks. The proposed
scheme for replacement considers the time interval between the
recent references, size and consistency as key factors for
replacement. Simulation study shows that the proposed
replacement policy can significantly improve the cache
performance in terms of cache hit ratio and query delay
