Fitness function computations are a bottleneck in genetic algorithms (GAs). Caching of partial results from these fitness computations can reduce this bottlenec_J¢. We provide a rigorous analysis of the run-times of GAs with and without caching. By representing fitness functions as classic Divide and Conquer algorithms, we provide a formal model to predict the efficiency of caching GAs vs. non-...

We address the worst-user bottleneck of wireless coded caching, which is known to severely diminish cache-aided multicasting gains due fundamental worst-channel limitation multicasting. consider quasi-static Rayleigh fading Broadcast Channel, for we first show that effective caching gain standard XOR-based coded-caching scheme completely vanishes in low signal-to-noise ratio (SNR) regime. Then,...

Vehicular edge networks (VENs) connect vehicles to share data and infotainment content collaboratively improve network performance. Due technological advancements, growth is accelerating, making it difficult always mobile devices locations. For vehicle-to-vehicle (V2V) communication, are equipped with onboard units (OBU) roadside (RSU). Through back-haul, all user-uploaded cached in the cloud s...

Most of caching proxy servers are installed between the Internet and enterprise networks (aka the Intranet). The performance of the caching proxy server is very important for WWW service because the server handles all of the WWW transactions in the organization. In this paper, as a performance measure of the caching proxy server, we exploit the WWW object retrieval time of clients through the c...

O are increasingly choosing to implement service-oriented architectures to integrate distributed, loosely coupled applications. These architectures are implemented as services, which typically use XMLbased messaging to communicate between service consumers and service providers across enterprise networks. We propose a scheme for caching fragments of service response messages to improve performa...

In this paper, we present the use of semantic caching in the environment of schema-based super-peer networks. Different from traditional caching, semantic caching allows the answering of queries that are not in the cache directly. The challenge of answering the queries using the cache is reduced to the problem of answering queries using materialized views. For this purpose, we implemented the M...

Latency and costs of Internet-based services are driving the proliferation of web-object caching. Memcached, the most broadly deployed web-object caching solution, is a key infrastructure component for many companies that offer services via the Web, such as Amazon, Facebook, LinkedIn, Twitter, Wikipedia, and YouTube. Its aim is to reduce service latency and improve processing capability on back...

Various dynamic content caching approaches have been proposed to address the performance and scalability problems faced by many Web sites that utilize dynamic content generation applications. Proxy-based caching approaches store content at various locations outside the site infrastructure and can improve Web site performance by reducing content generation delays, firewall processing delays, and...

Many network links in developing regions are low-bandwidth or intermittent. In addition to the inherent connection constraints, web browsing over these networks is an extremely painful experience due to inappropriate cache design. A single cache miss during browsing may cause a stall on the order of minutes or even hours. To improve web cache performance, we propose a new model of web caching p...
