Mobile computing seminar

  1. 1. WirelessApplicAtion protocol 1
  2. 2. definition Wireless Application Protocol“set of rules governing the transmissionand reception of data by computerapplication on via wireless devices likemobile phones “ 2
  3. 3. WhAt is WAp?is an application communication protocol.is used to access services and information.is inherited from Internet standards.is for handheld devices such as mobile phones.is device independent, network independent. 3
  4. 4. continued…is the leading standard for information services on wirelessterminals like digital mobile phones.is a protocol designed for micro browsers.enables the creating of web applications for mobile devices.uses the mark-up language WML (not HTML). 4
  5. 5. history of WApWAP is published by the WAP Forum, founded in 1997 byEricsson, Motorola, Nokia, and Unwired Planet.Forum members now represent over 90% of the global handsetmarket, as well as leading infrastructure providers, softwaredevelopers and other organizations. 5
  6. 6. WAp forum members CCL 6
  7. 7. GoAls of WApAccording to the WAP Forum, the goals of WAP are to be: Open to all. Independent of wireless network standard. Proposed to the appropriate standards bodies. Scalable across transport options. Scalable across device types. Extensible over time to new networks and transports. 7
  8. 8. internet model 8
  9. 9. WAp model 9
  10. 10. WAp GAteWAy/proxyIts an entity that connects the wireless domain with theInternet.WSP is a binary version of HTTP.The Wireless Markup Language (WML) has been adapted todevelop optimized WAP applications.Encoding WML is one of the tasks performed by the WAPGateway/Proxy. 10
  11. 11. hoW it Works? 11
  12. 12. feAtures of WAp1. Interoperability: WAP is an open license-free standard, which ensures that WAP-compliant devices are interoperable.2. Scalability: WAP applications scale across a variety of wireless transport options like GSM SMS, GSM USSD, IP, CDMA, etc., and also across a wide range of wireless terminals from hand sets to powerful PDAs.3. Extensibility: WAP has been designed as a future-proof technology. It is extensible over time to new networks and transports thereby protecting the mobile network 12
  13. 13. continued…4. Flexibility: WAP is a flexible solution that caters to the requirements of various types of applications by providing service options like connection mode and connection-less services, with or without end-to-end security.5. Reusability: WAP specification extends and adapts existing Internet standards such as HTTP, IP, Proxy technology, SSL, TLS, XML, HTML, etc., to wireless environment instead of defining a new set of standards. 13
  14. 14. WAp lAyered Architecture 14
  15. 15. WAp protocols• Wireless Application Environment (WAE). To build services in wireless domain comprises of multiple components to provide facilities like, • User agent • Wireless Markup Language • WMLScript • Wireless Telephony Application • WAP Push Architecture • Content Formats 15
  16. 16. WAp push ApplicAtion behAviour 16
  17. 17. hoW the push operAtion is performed ? 17
  18. 18. continued…• WSP (Wireless Session Protocol) Provides the application layer of WAP with a consistent interface for two session services. A connection-oriented service that operates above the transaction layer protocol WTP. A connectionless service that operates above a secure or non-secure datagram service (WDP). 18
  19. 19. continued…• WTP (Wireless Transaction Protocol) Provide efficient request/reply based transport mechanism suitable for devices with limited resources over networks with low to medium bandwidth. WTP Push mode allows server to “push” data to a client without request WTP/WDP uses less than half the packets that TCP/IP uses to transfer the same amount of data. 19
  20. 20. continued…• WTLS (Wireless Transport Layer Security) Is a security protocol ,Derived from Secure Sockets Layer (SSL). WTLS is intended for use with the WAP transport protocols and has been optimized for use over narrow-band communication channels. It provides the following features, ->data integrity ->privacy ->authentication 20
  21. 21. continued…• WDP (Wireless Datagram Protocol) The Transport layer protocol in the WAP architecture Provides a common interface to the Security, Session, and Application layers Able to function independently of the underlying wireless network. This is the key to global interoperability can be achieved using mediating gateways 21
  22. 22. compArision Protocol Web WAP Layers Markup Languages HTML WML Scripting languages VBScript ,JavaScript WMLScriptSession and transaction HTTP WSP,WTP layers Security TLS-SSL WTLS Delivery Service TCP,UDP WDP IP Bearer 22
  23. 23. usAGe-Corporate Applications: Sales force automation where salespeople use their WAP enabled handsets to get instant, directaccess to the latest pricing, latest news, competitiveinformation any time, anywhere.- Online Services: Banking: Users can get their current balance, transferfunds between accounts and receive fax of a mini-statement. Electronic Commerce: Subscribers can use their handsetjust like their PC to purchase products and services over theWeb. 23
  24. 24. continued…-Tele services Prepaid Services: With a WAP-enabled phone, prepaidsubscribers can see their current balance with the press of abutton. By pressing another button, they can also rechargetheir account by entering a credit card or voucher number intothe handset.-Personal Productivity Email: Using WAP users can keep track of their emailright from their handset.-Others include: - Interactive Chat - Auctions - Games 24
  25. 25. benefits2. Portability3. Easy to use4. Access to a wide variety of services on a competitive market5. The possibility of having personalised services6. Fast, convenient, and efficient access to services 25
  26. 26. drAWbAcks• Small screens: For web phones, theres an incredibly small viewing area; palmtops are barely better.• Speed of access: All devices have slow access.• Limited or fragmented availability: Wireless web access is sporadic in many areas and entirely unavailable in other areas. 26
  27. 27. ApplicAtions Some of the interesting applications of WAP (already existing or being worked on) are:• Computer Sciences Corporation (CSC) and Nokia are working with a Finnish fashion retailer who plans to send clothing offers direct to mobile telephones using a combination of cursors, touch screen technology and WAP to allow would-be shoppers to hot-link to order-entry pages on the web.• In Finland, children already play new versions of competitive games such as "Battleships", via the cellular networks. In the music world, Virgin Mobile in the UK offers to download the latest pop hits to customers in a daily offering. 27
  28. 28. continued…• Scala has developed several WAP products for small to medium-sized companies which would allow, for example, a field sales force to access customer order information and stock availability details via a WAP handset.• A key growth area for the technology will be business-to- workforce, with companies using WAP applications to reach employees at any time. Scala is currently working on time- sheet applications and techniques for entering and filing expense claims via the mobile phone.• Nokia says applications that will benefit from WAP include customer care and provisioning, message notification and call management, e-mail, mapping and location services, weather and traffic alerts, sports. 28
