Co-operative cache based data access in ad hoc networks

Wireless ad hoc network is a collection of autonomous nodes or terminals that communicate with each other by forming a multihop radio network and maintaining connectivity in a decentralized manner. Since the nodes communicate over wireless links, they have to contend with the effects of radio communication, such as noise, fading, and interference. In addition, the links typically have less bandwidth than in a wired network. Each node in a wireless ad hoc network functions as both a host ....etc

A modern storage hierarchy combines random-access memory, magnetic disk, and possibly optical disk or magnetic tape to try to keep pace with rapid advances in processor performance. I/O devices such as disks and tapes are considered reliable places to store persistent data such as user files. However, random-access memory is viewed as an unreliable place to store persistent data because it is vulnerable to power outages and operating system crashes .Memory's vulnerability to power outages is straightforward to understand and fix. A $100 uninter ....etc

Introduction

Object oriented programming has been the dominant programming paradigm for more than a decade.

OOP languages provide a rich set of features that provides significant software engineering benefits.

The increased productivity provided by these features comes at a justifiable cost of complexity in the runtime environment ,which actually leads to reduced performance and increased energy consumption of programs.

The memory hierarchy of high performance and embedded processors has been shown to be one of the major energy consumers. Extrapolating the current trends, this portion is likely to be increased in the near future. In this paper, a technique is proposed which uses an additional mini cache, called the L0-cache, located between the I-cache and the CPU core. This mechanism can provide the instruction stream to the data path, and when managed properly, it can efficiently eliminate the need for high utilization of the more expensive I-cache.

Adaptive Replacement Cache

Abstract :

We consider the problem of cache management in a demand paging scenario with uniform page sizes. We propose a new cache management policy, namely, Adaptive Replacement Cache (ARC) that has several advantages. In response to evolving and changing access patterns, ARC dynamically, adaptively, and continually balances between the recency and frequency components in an online and self tuning fashion. The ARC uses a learning rule to adaptively and continually revise its assumptions about the w ....etc

If you have been shopping for a computer, then you have heard the word cache. Modern computers have both L1 and L2 caches. You may also have gotten advice on the topic from well-meaning friends, perhaps something like Don't buy that Celeron chip, it doesn't have any cache in it!. Caching is a technology based on the memory subsystem of your computer. The main purpose of a cache is to accelerate your computer while keeping the price of the computer low. Caching allows you to do your computer tasks more rapidly.
