“…In the simulations, the loss probability P loss is ranged from 0.1 to 0.4. We compare our PEN algorithm with the PNC method [17] mentioned in Section 2.1, where the PNC method attempts to recover the maximum number of lost DVB-H packets in each superframe. Because we focus on studying the performances of different network coding schemes, it is assumed that the communication in the recovery network is reliable.…”

“…Yang et al [17] propose a prioritized network coding (PNC) method to deal with error recovery in a DVB-IPDC system, where the BS in a recovery network is allowed to broadcast a fixed number of coded packets in its cell such that the BS can recover the maximum number of lost DVB-H packets while minimize the total number of DVB-H packets discarded because of passing their deadlines. However, the PNC method assumes that all DVB-H packets are homogeneous.…”

SUMMARYThe digital video broadcasting-handheld (DVB-H) standard is developed by European Telecommunications Standards Institute to broadcast digital videos to handheld devices, but data loss is a critical issue due to the broadcast behavior. On the other hand, DVB-Internet protocol datacasting (DVB-IPDC) integrates DVB-H with an Internet protocol-based wireless network to provide bidirectional communication. We adopt this wireless network to deal with data retransmission and call it a recovery network. The paper argues that network coding can improve retransmission efficiency of the recovery network because DVB-H packet loss often exhibits high correlation. In addition, DVB-H packets may be heterogeneous in the sense that they have different importance. According to these two arguments, the paper considers that DVB-H packets are associated with different profit depending on their importance and proposes an˛-maximum profit network coding problem. It asks the base station in the recovery network to use no more than˛coded packets for handheld devices to retrieve the lost DVB-H packets such that the overall profit is the maximum. An efficient exclusive-or coding scheme, namely the profit-based exclusive-or network coding (PEN) algorithm, is proposed to solve this problem. Extensive simulation results also verify the effectiveness of the PEN algorithm.

“…However, none of them apply network coding to facilitate the retransmission process of the recovery network. The work of [13] proposes a prioritized network coding (PNC) problem in DVB-IPDC, where the BS is allowed to broadcast a fixed number of coded packets in its cell such that the BS can recover the maximum number of lost packets while minimize the total number of packets discarded due to passing their deadlines. However, the PNC problem does not consider that packets have different benefits.…”

DVB-H is developed to broadcast digital videos to handheld devices, but data loss is a concern due to the broadcast behavior. On the other hand, DVB-IPDC combines a wireless network with DVB-H to provide bidirectional communications. Such a wireless network can be used to handle data retransmissions and we call it a recovery network. The paper argues that network coding can improve retransmission efficiency of the recovery network since packet loss often exhibits high correlation. Besides, packets are heterogeneous in the sense of priority or importance. Thus, recovering different packets can obtain different benefits. Based on these two arguments, the paper proposes a maximum benefit problem, which asks the base station in the recovery network to use a limited number of coded packets for handheld devices to retrieve their lost packets such that the overall benefit is maximum. An efficient XOR coding scheme is developed to solve this problem. The paper contributes in addressing a new coding issue in DVB-IPDC.

DVB-H is developed to broadcast digital videos to mobile handsets, but data loss is a concern due to the wireless broadcasting nature. In this paper, take WiMAX as an IPbased wireless network to recover the loss packets in DVB-H, and take E-WP based on network coding as the encoding packet selection algorithm. Furthermore, a prioritized scheme EWP-PNC based on E-WP packet selection algorithm is proposed. In this scheme, take a base station in WiMAX as encoding node to encode any two packets that meet the encoding and decoding necessary and sufficient condition into an encoding recovery packet according to the current lost packet distribution, and calculate the benefit of each encoding packet to decide the final priority of all encoding packets. The goals of this scheme are to improve the lost packet recovery ratio and reduce the discarded packet ratio. According to the simulation results, the validity of this scheme is proved.
