Query: Packet Loss Recovery in Broadcast for Real-Time Applications in Dense
  Wireless Networks   Packet loss recovery in wireless broadcast is challenging, particularly for
real-time applications which have strict and short delivery deadline. To
recover the maximum number of lost packets within a short time, existing packet
recovery solutions often rely on instantly decodable network coding (IDNC).
Some of these solutions can recover nearly the maximum number of lost packets
possible at the cost of collecting feedback from all (or a large percentage of)
users. This is impractical in dense networks. In addition, their runtime grows
with the number of users, which is not desirable due to the urgent delivery
deadline of real-time applications. In this work, we introduce RIDNC, a random
encoding approach to IDNC. We propose RACE, a light RIDNC encoder that can
recover nearly as many lost packets as the optimal RIDNC encoder. We compare
RACE with the CrowdWiFi encoder, a high performing packet loss recovery
solution used in CrowdWiFi, a commercial system for broadcasting live video in
dense networks. We show that RACE is up to two orders of magnitude faster than
the CrowdWiFi encoder, and recovers more lost packets in practice, where there
is not enough time to collect feedback from many users.
