  3. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. What is Bluetooth ? ● Tenth-century Danish viking & king HaraldBlatand (Bluetooth) ● Bluetooth - radio technology- frequency-hopping spread spectrum ● ISM band: 2.4 GHz. ● Short-range, Low cost , Low power connectivity solution Special Interest Group (SIG) ● Bluetooth first developed in Ericsson’s research laboratory 1994. ● SIG was formed in 1998 to promote the technology ● IEEE 802.15 is the standardization of Bluetooth ● v2.1+EDR adopted in July 2007 – Transmission rate 3Mbits/s ● v3.0 + HS adopted in April 2009 –transmission rate 24Mbit/s ● In July 2010 SIG reveled Bluetooth v4 , High speed based on Wi-Fi Application of Bluetooth ● Data transfer, audio streaming, GPS navigation ,video streaming. ● Video streaming – Spy cam , Monitoring system , Sharing movie ● In general - range is 10 meter

  4. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Bluetooth Protocol Stack The Logical Link Control and Adaptation Protocol (L2CAP) receives application data and adapts it to the Bluetooth format . √ Maintains a packet queue, √ Essential for streaming application Link Management Protocol (LMP) is responsible for radio link set up between nodes by the baseband layer . Other responsibility - manage piconets , monitors service quality. The service Discovery protocol (SDP) is used for investigation of connection between devices. The LMP uses the service Discovery protocol (SDP) to find out what service is available

  5. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Bluetooth Protocol Stack The baseband layer maintains Synchronous Connection-Oriented (SCO) links for voice & Asynchronous Connectionless (ACL) links for data. It controls and send data over the radio link HCI is the dividing line between software and hardware. The L2CAP and layers above it are currently implemented in software, and the LMP and lower layers are in hardware. The BTnode structure for simulation (video Streaming) - where upper part is default ns-2 agent and middle is the bluetooth extension . Bluetooth Network Encapsulation Protocol (BNEP) layer provided a consistent interface to (LL), transfer IP packets in PAN Profile via L2CAP channel , run PPP and emulates Ethernet

Bluetooth Protocol Stack Alternative controller besides EDR , √ consists three layer :- (1) Protocol Adaptation layer (2) alternative mac protocol (3) alternative Physical layer

  7. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Connection Establishment • 3 steps : • INQUIRY -> PAGE -> CONNECTION • First standby mode and listen for message over 32 hop frequency . • In a new environment, the device automatically initiates an inquiry to find an access point. All nearby access points respond with their addresses, and the device picks access point. Inquiry Scan Inquiry Scan Inquiry Search Inquiry Scan

  8. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Connection Establishment • 3 steps : • INQUIRY-> PAGE -> CONNECTION • - If inquiry is successful • Paging procedure synchronizes the device with access point. • Link Manager Protocol (LMP) establishes a link with the access point • LMP uses SDP for available service information & create L2CAP channel . Page Scan Page Scan Page Inquiry Scan

  9. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Connection Establishment • 3 steps : • INQUIRY-> PAGE -> CONNECTION • In active state master and slave listen, transmit and receive data • Point to be noted , in Inquiry state if there is no reply from a devices , then it stay as undiscoverable . Slave Slave Master Inquiry Scan

  10. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. What is Piconet ? • Piconet refers following key points: • 1. Short range • 2. Master - Slave • 3. Frequency Hopping • 4. Master + n slave ;n ≤ 7 • 5. Additional slaves- parked • ●Standard piconet -7 slaves • ● Up to 255 parked slaves • ● Active devices are assigned a 3- • bit active member address • ● Parked devices are assigned an 8- bit parked member address • ● Standby devices do not need an address

  12. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Video Streaming in Bluetooth : ● (LAN) or (Wi-Fi) - has band-width, delay and loss requirements ● Bluetooth link is little bit challenging ; many potential reason : □ Low bandwidth , out of range device , time –varying feature and interference with other devices or external sources Bluetooth Simulation in ns-2 : • ● BlueHoc (2001) - Developed at IBM – now out dated • ● UCBT (2005)- Developed at University of Cincinnati - support v2+EDR • ● HSBT (2010 NOV) - Developed at Cairo University • – Support latest Bluetooth v3+HS • ● However – Works only in ns-2.29 , need native linux machine . • Very Hard to simulate in modern machine without significant effort ; • such as downgrading the compiler

  13. Challenges Development Result Conclusion Bluetooth VSEBT An Adaptive Approach for Video Streaming and Evaluation Over Bluetooth Network. Insufficient Documentation : ● Working with ns-2 is hard where there is no proper documentation ● One have to create their own documentation for works ● Question : is it possible to do video streaming in BT node ? Information Compare with Bluetooth related papers/survey for video streaming over Bluetooth network. Ex : M.H.Chia , Salim Beg, Wang Xiaohang • Findings : • ● Streaming Via IP • -Some connection with existing simulation . • IP ?? > By BNEP, L2CAP • ● MPEG-4 Video Codec Existing video streaming schemes in “Wired” and “Wi-Fi” Ex :China-Henry , frank They Integrated ns2 for streaming & evaluation in wired and wi-fi
