System Model u1 u2 u1 u2 Helpers (Wireless/Mobile Video Servers) • Maintain Multiple Queues for Individual Users h1 u1 h2 u2 Users (Smartphone Users) • Operation: Admission Control  Determining quality mode of each chunk based on DPP algorithm for network utility maximization • Download chunks from Helpers [Reference] D. Bethanabhotla, G. Caire, and M. J. Neely, "Joint Transmission Scheduling and Congestion Control for Adaptive Streaming in Wireless Device-to-Device Networks,” Proc. Asilomar 2012. (Journal Version: http://arxiv.org/abs/1304.8083) 2
Operational Example [Example-Based Explanation] • User requests desired video to two helpers. Helper 2 WiFi-AP Helper 1 WiFi-AP 5 User WiFi-Station
Operational Example [Example-Based Explanation] Helper 2 WiFi-AP Helper 1 WiFi-AP 0 6 User WiFi-Station 0 • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size).
Operational Example [Example-Based Explanation] s13 Helper 2 WiFi-AP Helper 1 WiFi-AP s12 s11 7 User WiFi-Station • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size). • User does the random selection (helper 1 is selected). And the user lets helper 1 know that it should place the sub-chunks of chunk 1 (i.e., s11, s12, s13).
Operational Example [Example-Based Explanation] s13 Helper 2 WiFi-AP Helper 1 WiFi-AP s12 s11 8 User WiFi-Station • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size). • User does the random selection (helper 1 is selected). And the user lets helper 1 know that it should place the sub-chunks of chunk 1 (i.e., s11, s12, s13). • User requests next chunks (i.e., c2) to two helpers.
Operational Example [Example-Based Explanation] s13 Helper 2 WiFi-AP Helper 1 WiFi-AP s12 s11 3 9 User WiFi-Station 0 • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size). • User does the random selection (helper 1 is selected). And the user lets helper 1 know that it should place the sub-chunks of chunk 1 (i.e., s11, s12, s13). • User requests next chunks (i.e., c2) to two helpers. • Helper 1 will reply 3 and helper 2 will reply 0.
Operational Example [Example-Based Explanation] s13 Helper 2 WiFi-AP Helper 1 WiFi-AP s23 s12 s22 s11 s21 10 User WiFi-Station • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size). • User does the random selection (helper 1 is selected). And the user lets helper 1 know that it should place the sub-chunks of chunk 1 (i.e., s11, s12, s13). • User requests next chunks (i.e., c2) to two helpers. • Helper 1 will reply 3 and helper 2 will reply 0. • User selects the one which has the smallest queue backlog size. Thus, helper 2 is selected. And the user lets helper 2 know that it should place the sub-chunks of chunk 2.
Operational Example [Example-Based Explanation] s13 Helper 2 WiFi-AP Helper 1 WiFi-AP s23 s12 s22 s11 s21 • Now, instead of doing transmission scheduling, User selects helper 1 because user needs s11 in terms of playback order and user knows that helper 1 has the one (Greedy Pull for Minimum Delay). I need s11 11 • User requests desired video to two helpers. • Both helpers will reply zero (which is current backlog size). • User does the random selection (helper 1 is selected). And the user lets helper 1 know that it should place the sub-chunks of chunk 1 (i.e., s11, s12, s13). • User requests next chunks (i.e., c2) to two helpers. • Helper 1 will reply 3 and helper 2 will reply 0. • User selects the one which has the smallest queue backlog size. Thus, helper 2 is selected. And the user lets helper 2 know that it should place the sub-chunks of chunk 2. User WiFi-Station
Operational Example [Example-Based Explanation] Helper 2 WiFi-AP Helper 1 WiFi-AP • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is bad, so, helper 1 can transmit only one, i.e., s11. s23 s13 s22 s12 s21 s11 s11 12 User WiFi-Station
Operational Example [Example-Based Explanation] Helper 2 WiFi-AP Helper 1 WiFi-AP s23 s13 s22 s12 s21 s11 13 User WiFi-Station • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is bad, so, helper 1 can transmit only one, i.e., s11. • User requests next chunk (i.e., c3) to two helpers.
Operational Example [Example-Based Explanation] Helper 2 WiFi-AP Helper 1 WiFi-AP s23 s13 s22 s12 s21 2 3 s11 14 User WiFi-Station • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is bad, so, helper 1 can transmit only one, i.e., s11. • User requests next chunk (i.e., c3) to two helpers. • Helper 1 will reply 2 and helper 2 will reply 3.
Operational Example [Example-Based Explanation] s33 s32 s31 Helper 2 WiFi-AP Helper 1 WiFi-AP s23 s13 s22 s12 s21 s11 15 User WiFi-Station • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is bad, so, helper 1 can transmit only one, i.e., s11. • User requests next chunk (i.e., c3) to two helpers. • Helper 1 will reply 2 and helper 2 will reply 3. • User selects the one which has the smallest queue backlog size. Thus, helper 1 is selected. And the user lets helper 1 know that it should place the sub-chunks of chunk 3.

Thus, helper 1 is selected. And the user lets helper 1 know that it should place the sub-chunks of chunk 3. • Now, instead of doing transmission scheduling, User selects helper 1 again because user needs s12 in terms of playback order and user knows that helper 1 has the one (Greedy Pull for Minimum Delay). s11 I need s12 16 User WiFi-Station

If RSSI is good, then it can transmit more. Now, suppose that the channel is bad, so, helper 1 can transmit only one, i.e., s12. • (User doesn’t request chunks because c3 was the last one) • Now, instead of doing transmission scheduling, User selects helper 1 again because user needs s13 in terms of playback order and user knows that helper 1 has the one (Greedy Pull for Minimum Delay). • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is good, so, helper 1 can transmit three.
Operational Example [Example-Based Explanation] Helper 2 WiFi-AP Helper 1 WiFi-AP s33 • Now, instead of doing transmission scheduling, User selects helper 2 because user needs s21 in terms of playback order and user knows that helper 2 has the one (Greedy Pull for Minimum Delay). • Helper 2 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is good, so, helper 1 can transmit three. s23 s22 s21 s11 s12 19 User WiFi-Station s22 s13 I need s21 s23 s21 s31 s32
Operational Example [Example-Based Explanation] • Now, instead of doing transmission scheduling, User selects helper 2 because user needs s33 in terms of playback order and user knows that helper 1 has the one (Greedy Pull for Minimum Delay). • Helper 1 transmits sub-chunks for the given time. If RSSI is good, then it can transmit more. Now, suppose that the channel is good, so, helper 1 can transmit the all of remaining sub-chunks.
