Bluetooth



What is Bluetooth ?

● Tenth-century Danish viking & king Harald Blatand (Bluetooth)● Bluetooth - radio technology- frequency-hopping spread spectrum● ISM band: 2.4 GHz.● Short-range, Low cost , Low power connectivity solution

Application of Bluetooth

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

● Data transfer, audio streaming, GPS navigation ,video streaming.● Video streaming – Spy cam , Monitoring system , Sharing movie● In general - range is 10 meter

Bluetooth



Bluetooth Protocol Stack

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 Logical Link Control and Adaptation Protocol (L2CAP) receives application data and adapts it to the Bluetooth format . √ Maintains a packet queue, √ Essential for streaming applicationThe 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

Bluetooth




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 linkBluetooth Network Encapsulation Protocol (BNEP) layer provided a consistent interface to (LL), transfer IP packets in PAN Profile via L2CAP channel , run PPP and emulates EthernetHCI 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




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

Bluetooth



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 Search

Inquiry Scan Inquiry Scan

Inquiry Scan

Bluetooth




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

Inquiry ScanPage

Bluetooth




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

Bluetooth



What is Piconet ?

Piconet refers following key points:1. Short range2. Master - Slave3. Frequency Hopping4. Master + n slave ;n ≤ 75. 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

Bluetooth



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

Bluetooth



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

Existing video streaming schemes in “Wired” and “Wi-Fi”Ex :China-Henry , frankTheyIntegrated ns2 for streaming & evaluation in wired and wi-fi

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

Performance Parameter :

● Delay :Time taker for a packet ,transmit from source to destinationDelay :End time – Start Time

● Jitter : Represents variance of delay Jitter = {End to End Delay (j) – End to End Delay (i)} / (j-i), where j>i

● Throughput : Defines the Number of bits from (A to B / Observation)Throughput for each packet = {(CBR packet size in Bytes * 8 ) / End to End Delay /1000} (kbps)

● Loss : No, as we follow time manner strictly

Conclusion

We have developed -●Method for video streaming and evaluation over -Bluetooth (v2.1 & v3) -in maximum possible salves (7) -which support any video duration ●Two frameworks - can be applied over upcoming Bluetooth specification (v4)

Findings :√Encoding method is extremely important –√ The packet size & type 3-DH5

It can be believe that this research work is the first work with High speed Bluetooth connection as it is adopted very recently

Bluetooth



Conclusion

Further research-we consider experimenting with scatternet topology and to supports any video format

To face this challenge –Critical implementation methods (ex: new protocol design, node formation) have to be addressed for realistic video transmission and evaluation .

However, if we only concern with piconet another new topology can be created . If we can merge master of piconet with Wifi Router . Wifi Cum Bluetooth ( WB )
