Identification and Classification of Processing Unit Eligibility for Ubiquitous Computing Using Feature Selection Mechanism and Artificial Neural Network

Abstract

Ubiquitous Computing is a trending innovation that allows a user to have access to many computers in a transparent manner anytime anywhere thereby enhancing computing confidence. However, the full potential of ubiquitous computing is not yet realised due to challenges including changing location of mobile users, poor network infrastructure, limited system resources, and poor transaction processing model. This work is concerned with the development of a proactive support for active transaction coordination in ubiquitous computing environment. The specific objectives are to identify relevant values of predefined key features of processing units that greatly impact on ubiquitous computing and to predict the processing capability of processing units using relevant values of the predefined features. An object-oriented analysis and system design methodology is employed and the proposed processing unit eligibility identification mechanism and neural network-based classifier is shown to effectively support ubiquitous computing.

A Proposed Combinatorial System Design for Ubiquitous Transaction Processing Systems

“…In phase 1 of the communication algorithm as shown in figure 7, the transaction server (specifically the operations coordinator) sends a "request to send" message to all eligible processing units [6]. On getting a "Ready to Receive" or "Not Ready to Receive" message from the cohorts (That is, eligible processing units hosting the database management systems), the coordinator moves to phase 2 of the protocol as shown in figure 8 where it transfers the transaction logs plus the "prepare to commit" message to cohorts that are ready to receive transactions for execution.…”

“…These processing nodes are connected to one another through a communication network infrastructure. Distributed transaction processing and wireless network infrastructure form a backbone for ubiquitous computing [6]. Wireless devices and supporting programs are essential elements of ubiquitous computing environments.…”
