  1. Wireless Networks and Mobile Systems Lecture 15Summary

  2. Lecture Objectives • Provide a brief summary of the class • Approach and objectives • What we covered and what we did not cover Fundamentals: Summary 2

  3. Integrated Approach Topics MobileApplications Design • Location and Context Aware • Pervasive Computing Middleware • Middleware • Client-server computing • Peer-to-peer and ad hoc computing • Service discovery and control Characterization MobileNetworking • Mobile ad hoc networks • Mobile IP • Nomadic services • Security WirelessNetworks • IEEE 802.11 and Bluetooth • Mobility in wireless LANs • Wireless fundamentals Fundamentals: Summary 3

  4. Learning Objectives (1) • Describe the characteristics and operation of contemporary wireless network technologies such as the IEEE 802.11 wireless local area network and Bluetooth wireless personal area network • Describe the operation of the TCP/IP protocol suite in a mobile environment, including the operation of Mobile IP and a mobile ad hoc routing protocol • Mobile IP • OLSR MANET routing protocol • Describe security issues and current solutions for wireless networks and mobile systems • IEEE 802.11, WPA, and IEEE 802.11i Fundamentals: Summary 4

  5. Learning Objectives (2) • Use application program interfaces (APIs), such as Intel’s Personal Internet Client Architecture (PCA), Microsoft’s .NET Compact Framework (CF), or Sun’s Java 2 Micro Edition (J2ME), to realize mobile applications • Focus on .NET CF and UPnP • Design, implement, and test a prototype mobile application • Design, implement, and test a wireless access service Fundamentals: Summary 5

  6. Learning Objectives (3) • Measure and characterize the performance a wireless local area network, mobile routing protocol, and mobile application • Monitor the operation of mobile network protocols and applications using standard tools • iPERF, Ethereal, traceroute, ping Fundamentals: Summary 6

  7. What We Didn’t Cover (1) • Communications… • Physical level modulation and coding schemes • Spectrum allocation and utilization • Networking… • Cellular systems • Lots of additional protocols • Lots of additional complexity Wireless networks and mobile computing are both huge fields – so there are lots of topics that we didn’t cover or didn’t cover in sufficient depth Fundamentals: Summary 7

  8. What We Didn’t Cover (2) • Software design issues… • New environments and languages • Power-aware • Integrated hardware/software design • Lots of additional complexity • Hardware design issues… • Low power • Small form factor • Efficient reuse of resources • Integrated hardware/software design Fundamentals: Summary 8

  9. What We Didn’t Cover (3) • Human computer interaction… • Design for small displays • Gesture and touch recognition • Video integration • Speech • System issues… • Location detection • And lots more! Fundamentals: Summary 9
