Self-managing, disconnected processes and mechanisms for mobile e-business

Abstract

With the tremendous advances in hand-held computing and communication capabilities, rapid proliferation of mobile devices, and decreasing device costs, we are seeing a growth in mobile ebusiness in various consumer and business markets. In this paper, we present a novel architecture and framework for end-to-end mobile e-business applications such as purchasing, retail point of sales, and order management. The design takes into consideration disconnection, application context and failure modes to provide mobile users with seamless and transparent access to commerce and content activities. In our architecture, we consider a novel business process design based on state-machines and event management to handle disconnection and resource limitations. We designed, implemented and deployed a system for mobile ebusiness on clients integrated with private exchanges and sell-side servers.The e-business framework on mobile clients is implemented based on J2ME and open XML standards. A performance study of simple e-business transactions was done on the client using the above mechanisms and programming environment. We show that the performance of a purchasing process using the framework does reasonably well.

Modeling and Analysis of Mobile Service Processes by Example of the Housing Industry

“…Dustdar and Gall [16] as well as Sairamesch et al [17], [18] describe frameworks for distributed and mobile collaboration which can be used to develop software architectures for mobile systems. These frameworks are of particular interest for the MPL method because it is the methods aim to provide a systematic deduction of constraints for the software architecture on the basis of the process model.…”

Supporting dependable group‐oriented mobile transactions: redundancy‐based architecture and performance

“…Although routing and related issues have received considerable attention [2], only very little work exists for transactions in mobile services such as basic requirements [4], mobile teamwork functions [5], and virtual guide function for a tourist group [6]. So far, most of the transactionrelated research primarily deals with database access under connectivity problems such as pre-fetching data [7], detecting data conflicts between transactions [8], deploying transaction recovery [9], using synchronization [10], reducing interaction under intermitted connectivity [11], supporting disconnected mode of operation [12], using middleware [13], using pre-write for data availability during frequent disconnection [14], performing recovery for transactions [15], measuring effect of disconnection on the properties for transactions [16], using recovery protocol [17], deploying transaction manager to retrieve state information [18], and accessing commerce activities using state machines and event management to handle disconnection [19]. The use of basic time-out mechanisms for group-oriented mobile services has been suggested [4].…”

Group-oriented mobile services: Requirements and solutions

“…The work on transaction support in mobile environments primarily deals with database access and transaction completion for mobile users experiencing connectivity problems. This includes synchronization after re-connection to allow the completion of a transaction (Keller et al 1998), performing recovery for transactions under mobile disconnection (Pedregal-Martin and Ramamrithan 2002), using recovery protocol based on user interaction and state models (Vandermeer et al 2003), deploying transaction manager to store and retrieve transactional state information (Veijalainen et al 2003) and supporting continued access to commerce and content activities using state-machines and event management to handle disconnection (Sairamesh et al 2002). It can be concluded that the most of the work in group-oriented mobile services deals with membership management, multicast routing, and security, while the work on supporting mobile transactions primarily focuses on database access and recovery issues.…”
