CONCLUSION
The concept of e-commerce defines the general context of activities related to buying and selling products and services using electronic media and utilizing state-of-the-art technologies. Examples include the World Wide Web, electronic data interchange, e-mail, electronic fund transfers, and smart cards. It is increasingly clear that the use of e-commerce is becoming an important new tool for the manufacturing and retail industries and an imperative new development for all industries striving to maintain a competitive edge. Companies can use the mechanisms and technologies offered by e-commerce to put their stores online. At the same time, customer mobility has emerged an important catalyst triggering a new paradigm shift that is redefining the way we conduct business. An important feature of mobile commerce is that the online store is accessible 24 hours per day to a potentially huge customer base scattered around the world. By their very nature, mobile commerce applications will rely increasingly on wireless communications. To be cost-effective and thus economically viable , these applications will have to reach a wide consumer base. In turn , this suggests that a wide coverage ‚ indeed, a global one ‚ is a must in mobile commerce. Such a global coverage is only achieved by a combination of terrestrial and satellite networks.
In this chapter we presented a novel paradigm for future m-commerce multimedia communications and applications ‚ QoS multimedia ( virtual reality) anytime anywhere market system , which integrated with other multifunctional multimedia e-applications (e-learning, e-health, e-culture, e-work, etc.) in cost-effective manner.This paradigm is likely to open novel far-reaching opportunities for m-commerce. We have also proposed an implementation of this paradigm based on our novel QoS-oriented MAC technology and on the fully distributed all-IP/ATM architecture.
The proposed QoS-oriented MAC technology and the all-IP/ATM architecture will provide advanced broadband communication multiservice for the mobile and geographical distributed user anytime, anyplace, of any kind, of any quality, and in any quantity in a mass-market and low-cost manner. The new advanced QoS-oriented long-delay ATM MAC technology and fully distributed low-cost all-IP/ATM architecture are necessary to carry out these impressive goals. This article presents a proposal of such advanced wireless environment technology and architecture.
The proposed QoS-oriented MFMAC technology is based on TBR-RS MAC novel protocol. This technology uses RS opportunities with the object of the main MAC mechanism's effective implementation. The efficiency of the proposed long-delay ATM MAC mechanisms ensures closely to optimal capabilities. It further ensures a highly effective and completely distributed dynamic control of QoS simultaneously and opens promising possibilities for all-MPLS/ATM wireless architecture.
The proposed long-delay ATM MFMAC technology opens novel opportunities to provide a whole range of communication services ‚ mobile broadband Internet/intranet/extranet access, customized infotainment, multimedia messaging, video, rich voice, location-based services for business and also consumer. The novel all-MPLS/ATM-MFMAC architecture is based on using known multiprotocol techniques on the top sub-layers and common multifunctional and the proposed universal MFMAC protocol on channels' sub- layers through all networks' hierarchy ‚ core , backbone, and access networks.
