Wei Wei and Avideh Zakhor Presented by Venkat Rajiv Vasireddi Pradeep Ramamoorthy Video Communication Why is video communication far more challenging when compared to data communication. 6-. 1. Chapter 6. Wireless and Mobile Networks. Computer Networking: A Top Down Approach . 4. th. edition. . Jim Kurose, Keith Ross. Addison-Wesley, July 2007. . Computer Networking: A Top Down Approach . Multicast. . is the delivery of a message . to . a group of . receivers . simultaneously in a single transmission from the . source. The source sends a . message to a group. The message then is delivered to all members of the group. 2. Multicasting. Multicast communications refers to one-to-many or many-to-many communications. . IP Multicasting refers to the implementation of multicast communication in the Internet. Multicast is driven by receivers: Receivers indicate interest in . 802.11aa: Improvements . on video . transmission over . Wireless LANs. Speaker . : Song-. Ferng. . Wang. Advisor . : . Dr. . Ho-Ting Wu. Date . : 2014/1/6. Introduction. IEEE 802.11 multicast issues . 6-. 1. TCP over ATM:. UBR: for delay-tolerant applications . e.g., ftp, telnet. ABR: . for delay sensitive applications, e.g., on-line sessions. provides explicit congestion signaling. TCP over UBR:. The Story So Far. Switched . ethernet. is good. Besides switching needed to join even multiple classical . ethernet. networks. Routing is expensive, learning switches seem cheaper. Flooding in a network with a cycle of switches is bad (why?). 6-. 1. Chapter 6. Wireless and Mobile Networks. Computer Networking: A Top Down Approach . 4. th. edition. . Jim Kurose, Keith Ross.

Describe quality of service in a campus infrastructure to support advanced services.. Power. Processor. Radio. Sensors. Memory. Today, we look much cuter!. And we’re usually carefully deployed. A Typical Sensor Node: . TinyNode. 584. TI MSP430F1611 microcontroller @ 8 MHz. 10k SRAM, 48k flash (code), 512k serial storage. .. Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies. 6-. 1. Chapter 6. Wireless and Mobile Networks.
