In the mobile ad hoc network, a mobile host can communicate with others anywhere and anytime. Cooperative caching scheme can improve the accessibility of data objects. However, the cache hit ratio is reduced and access latency becomes longer significantly due to the mobility of MHs, energy consumption in battery, and limited wireless bandwidth. In this paper, we propose a novel cooperative caching...
The simplest broadcasting scheme in the mobile ad hoc networks (MANETs) uses flooding which may result in the broadcast storm problem. The Multipoint Relays (MPR) is another broadcasting scheme for solving the broadcast storm problem. In MPR, the mobile hosts (MHs) use a greedy algorithm to find a connected dominating set (CDS) by the exchange of 2-hop neighbor information. In order to reduce the...
In this paper, we use Web session objects and database-related dynamic Web cache to implement the dynamic Web cache system in Tomcat Web server. We show how to build the dependency between dynamic Web pages and the underlying database fields and session objects. Our experimental results show that Tomcat with proposed dynamic Web cache can increase the stability of web server and improves Web server...
Mobile ad hoc wireless network is a special network without any infrastructure. The routing path could be broken easily because every host in such network is able to move freely. If the routing path is broken, the source host must reconstruct another new route. This will increase higher network overhead and latency and cause a decrease in the data throughput. In this paper, AODV and DSR schemes are...
