PRESENTATION ON SURVEY OF RESEARCH Research Topic ( MIGRATION OF WEB SERVICE TO MOBILE AND WIRELESS APPLICATION ‘S) GUIDED BY: PRESENTED BY: MISS. UMA BHATNAGAR ANOOP SINGH ATUL KUMAR DUBEY ABHISHEK SACHAN

I NTRODUCTION : SOAP -: (SIMPLE OBJECT ACCESS PROTOCAL) WSDL-: (WEB SERVICES DESCRIPTION LANGUAGE) UDDI-: (UNIVERSAL DESCRIPTION DISCOVERY AND INTEGRATION)

S PECIFICATIONS OF WS Some specifications have been developed or are currently being developed to extend web services capabilities. These specifications are generally referred to as WS-*, which are-:WS-* WS-Security WS –Reliability WS-Transaction

T ECHNICAL S PECIFICATION U SED I N WS-R ESOURCE F RAMEWORK :

MOBILE PHONE POPULATION: 2.5 billion mobile phones A person carries a pervasive mobile device and gets information anytime, anywhere and anyone. Mobile phone population is expected to be 4 billions by end of 2010 –every 2 persons in 3 people will have a mobile phone

C ONT …. In China, mobile phone users are 430 million against 123 million of Internet users. In India, there are 125 million mobile phones against 60 million Internet users. Sun announced more than 74 % of JAVA enabled handsets were sold worldwide in year 2007.

F IRST UNDERSTAND - WIRELESS ENVIRONMENT Mobile Applications (M-Business, M-Business, M- Government, M-Life, Positional Apps) Platforms to Support Mobile Applications Mobile IP Wireless middleware (WAP, iMode, J2ME, BREW, MIT) Wireless Networks Wireless PANs (Sensor Networks, Bluetooth, UWB) Wireless LANs (Wi-Fi, a to n) Wireless Local Loops and Free Space Optics Cellular networks: from 1 to 5G Networks Satellite communications and Deep Space Networking

CHALLENGES IN MOBILE High Latency Narrow Bandwidth Limited Computation Small Memory Space Battery Life

H OW WE CAN MIGRATE !! By using high bandwidth cellular network-4G Strong feature of XML J2ME based web services DOT.NET based web services Strong wireless devices many types of Smartphone operating systems available-Smartphoneoperating systems Symbian, Android, Blackberry, Palm Pre, Apple iOS, Windows Mobile Professional (touch screen), and Windows Mobile Standard (non-touch screen) SymbianAndroidBlackberryPalm PreApple iOS Windows Mobile

AGENDA Web Services Mobile Technology Challenges in Mobile Technology

TRADITIONAL RPC & WEB SERVICES TRADITIONAL RPC Within enterprise Tied to a set of programming languages Procedural Usually bound to a particular transport Firewall-unfriendly Efficient processing (space/time) WEB SERVICES Between enterprises Programming language independent Message driven Easily bound to different transports Firewall-friendly Relatively inefficient processing 4

HANDHELD FLEXIBLE REPRESENTATION (HHFR)

LIMITED COMPUTATION Presently all XML documents are textual data. So we use encoding and decoding techniques for non-textual data into textual data. It is an expensive process especially for relatively low-powered mobile devices to convert non-textual data into and from textual data. So we will use in our application Binary Representations of SOAP Message. Its approved by W3C organization

SMALL MEMORY SPACE In Mobile minimum 128 KB of flash memory for persistent storage and 32 KB (or more) of volatile memory to be available for runtime allocation. Traditionally we use DOM and SAX parsers for parsing XML documents. But these parsers take more memory because these are designed for Personal Computers. Using KXML and KSOAP instead of XML Parsers (DOM & SAX) and SOAP. It include the specific library files only. So it will reduce the application size.

N AME OF R ESEARCH P APER High Performance approach in Mobile & Wireless Technology.
