  2. Introduction Mobile Middleware • What is Mobile Middleware • Mobile Middleware for Enterprise • Adaptation • Agents • Service Discovery

  3. Introduction Mobile Middleware • What is Mobile Middleware • Definition • “Middleware is software that supports mediation between other software components, fostering interoperability between those components across heterogeneous platforms and varying resource levels,” – Fundamentals of Mobile and Pervasive Computing, by Adelstein, Gupta, Richard III, and Schwiebert, McGraw-Hill, 2005

  4. Introduction Mobile Middleware – What is Mobile Middleware • Definition from www.bitpipe.com/tist/Mobile-Middleware.html • Mobile middleware allows for the implementation of distributed applications connecting mobile and enterprise applications over wireless networks • Provide the “black box” technology that connects mobile devices on the front lines of the enterprise to the back-end applications running on corporate servers

  5. Middleware for Enterprise • Example Applications • Wireless email • Speech middleware • Firewall and mobile VPN (Virtual Private Network) • Network connectivity • Device management • Enterprise Access • CRM (Customer Relationship Management) • EAI (Enterprise Application Integration) • Enterprise data & information integration • Insurance Claim

  6. Open Source Mobile Middleware • Mobile Application Support and Management Environment • Advising service • Discovery service • Middleware Infrastructure • Generic Mobile APIs • Application Specific Mobile APIs

  7. Middlewares for Enterprise • Oracle, http://www.oracle.com/index.html • CTO Summit, http://www.oracle.com/events/ctosummit/index.html • Successful Mobile Strategies, 11 minutes • Mobile Field Service, http://www.oracle.com/applications/service/mobfsrv_cont.html

  8. Middlewares for Enterprise • Sybase – iAnywhere Solutions, • Mobile Services A-Z, http://www.sybase.com/mobileservices/mobileservicesa-z • iAnywhere, http://www.sybase.com/detail?id=1049903 • SAP • Siebel

  9. Middlewares for Enterprise • Nokia, Mobile Middleware – Nokia Intellisync • http://usa.nokia.com; http://www.nokiaforbusiness.com/innovate • Support more than 400 different mobile devices from over 6 different OS • Palm, Symbian, Windows Mobile, Windows OS, PocketPC, SyncML, BREW • Connect, sync and extend solutions with Microsoft Exchange, Lotus Domino, Novell Groupwise, IMAP/POP3 email interface

  10. Middlewares for Enterprise • Novell, http://www.novell.com/groupwise • Mobility Solutions • Groupwise Mobile Server • Blackberry Enterprise Server

  11. Middlewares for Enterprise • IBM • Net’s future is mobile middleware, December 7, 2006, eWeek, http://www.eweek.com/article2/0,1895,2069820,00.asp • Data-sharing middleware platform for mobile devices • Code name: Infinity – based on a number of industry-standard technologies, including XML, HTTP, HTML, JavaScript, and Bluetooth technology

  12. Middlewares for Enterprise • IBM Webcast: • IBM WebSphere Everyplace Access, http://www-128.ibm.com/developerworks/websphere/techjournal/0209_tan/tan.html • Workplace Client Technology, Micro Edition (WCTME) – J2EE and Eclipse • Extend your applications to mobile devices, http://www-1.ibm.com/partnerworld/pwhome.nsf/mktgsale/eac_webcasts_tech28apr.html

  13. Middlewares for Enterprise • Sprint Campus Connect, http://www.sprint.com/business/

  14. Adaptation • Tasks • Adapt behavior and expectations to conserve scare resources • Adjust quality of service (QoS) – guarantee performance • How should adaptation be supported? • Monitor resources and adapt appropriatly

  15. Agents • Allowing programs to move autonomously about a network in order to access remote resources • Migrate to servers -> access data or computational resources -> migrate again -> return to home base • Benefits • Disconnection is easily supported • Access to large amount of data to solve problem • Allow the functionality of servers to be expanded dynamically

  16. Service Discovery • Extend the client-server paradigm • Discover needed service on-demand • Bluetooth Service Discovery Protocol
