Recent research has exploited the multi-homing property (one terminal with multiple network interfaces) of modern devices to improve communication performance in wireless networks. Cooperative Peer-to-peer Repair (CPR) is one example where given simultaneous connections to both a Wireless Wide Area Network (WWAN) and an ad-hoc Wireless Local Area Network (WLAN), peers receiving different subsets of...
By exploiting multiple network interfaces on one device, e.g., Wireless Wide Area Network (WWAN) and Wireless Local Area Network (WLAN), peers receiving different subsets of WWAN broadcast/multicast packets can perform Cooperative Peer-to-peer Repair (CPR) by exchanging received WWAN packets with their local WLAN peers. This effectively improves the transmission success from a WWAN broadcast/multicast...
Because of frequent wireless packet losses and inapplicability of retransmission-based schemes due to the wellknown NAK implosion problem, providing high quality video multicast over wireless wide area networks (WWAN) remains difficult. Traditional joint source/channel coding schemes for video multicast-optimal bit allocation among source coding and channel coding such as forward error correction...
By providing coding ability at intermediate nodes, network coding has been shown to improve throughput in wireless broadcast/multicast networks. Considering a scenario where wireless ad-hoc peers cooperatively relay packets to each other to recover packets lost during MBMS broadcast, we show that by first imposing coding structures globally and then selecting the appropriate types within the structures...
By providing coding ability at intermediate nodes, network coding has been shown to improve network throughput in broadcast/multicast wireless networks. In this paper, we show that by imposing coding structure, network coding can be further optimized specifically for video streaming in a rate-distortion manner, in a scenario where wireless adhoc peers cooperatively relay packets to each other to repair...
