This document discusses mobile computing and its expansion through Eclipse. It defines user and device mobility and examines the constraints of wireless devices and networks compared to traditional computing. Mobile computing aims to make the internet accessible through mobile devices in a compatible, transparent, scalable, and secure way. The document outlines various mobile and wireless applications and concludes that studying mobile computing can provide insights into wireless networks, access control, and security.
Mobile computing
- 2. “What it means is Eclipse now gets to expand its footprint beyond the traditional computing environ ment, and it gets to reach out to the mobile device.
- 3. TWO KINDS OF MOBILITY: •USER MOBILITY •DEVICE MOBILITY
- 4. WHAT IS MOBILE COMPUTTING: •DEFECTOR STANDARD BY ITSELF •MAJOR PART OF WIRELESS COMMUNICATION TECHNOLOGY
- 5. Application Transport Network Data Link Network Network Data Link Data Link Physical Physical Application Transport Network Data Link Physical A SIMPLIFIED REFERENCE MODEL
- 6. The wireless devices represent the ultimate constrained computing device with: •Less powerful CPUs, •Less memory (ROM and RAM) •Restricted power consumption •Smaller displays •Different input devices (e.g., a phone keypad, voice input, etc.)
- 7. On the network side, wireless networks are constrained by •Less bandwidth •More latency •Less connection stability •Less predictable availability
- 8. Goals, assumptions, and requirements: The Internet is the network for global data communication with hundreds of millions of users. So why not simply use a mobile computer in the Internet?
- 11. APPLICATIONS: 1. Vehicles 2. Emergencies 3. Business 4. MOBILE AND WIRELESS DEVICES 5. Sensor: 6. Pager: 7. Mobile Phones: 8. Personal digital assistant: 9. Palmtop/pocket computer: 10.Notebook/Laptop:
- 12. CONCLUSION Mobile Computing and Communications is useful for wireless Networks. The study of different versions will give differences between Mobile Computing and Communications, Access Control, Security etc.,
