  1. MiddlewareforMobile Computing By- Chitra G. Sahu M-Tech CSE, RCOEM. Guided by- Dr. D. S. Adane

  2. Overview • What is Mobile Computing • What are Mobile Computing Platform • What is Middleware • Role of Middleware • Types of Middleware Technologies • What is Context-aware Middleware • Proposed Plan • References

  3. Evolution of Computing Mobile Computing Internet Networking LAN / WAN Multi User OS Batch User OS Single User OS

  4. What is Mobile Computing • Mobile Computing Functions- • User mobility • Network mobility • Device mobility • Session mobility • Service mobility • Host mobility

  5. Mobile Computing Platforms • Local platform services • Interconnectivity software • Network transport services

  6. What is Middleware

  7. Common Features Of Middleware • Connection and message delivery • Transformation • Detection and storage • Optimization • Security • Operation support

  8. The Limitations of Mobile Computing Mobile Devices Network Connection and Physical Host Mobility Due to these limitations, conventional middleware technologies designed for fixed distributed systems are not prepared to support mobile systems

  9. Requirements for Mobile Computing • Dynamic reconfiguration • Adaptions • Asynchronous interaction • Context-awareness • Lightweight middleware

  10. Types of Middleware Technologies • Reflective Middleware • Tuple Space Middleware • Context-Aware Middleware • Event-Based Middleware

  11. Requirements Vs Categories

  12. Context Aware Middleware • Why Context Aware Middleware • Current Context Aware Middleware • free developers from the implementation of low-level details related to the network, like • Concurrency Control • Transaction management • Network Communication • So we can focus on application requirements.

  13. Context-aware middleware • What is Context.

  14. Architecture of context-aware system

  15. Google Search Results • Who is “ANNA” ?? • Earlier

  16. Context-Aware Middleware Issues Issues of Context aware middleware • With the birth of context-aware middleware many issues came out, like • Security, • Balance of user control, • Sensing the context and conflicts. • we examine the balance of user control in the new middleware approach.

  17. Proposed Plan Balance of user control, However, context-aware applications may not always adapt as the user expects, and may cause users to feel loss of control over the behavior of their applications
