“…The Implicit-Primal-Dual scheme for flow control in live streaming peer-to-peer systems is introduced in [23]. [24], which is the closest to our work, proposes a scalable video broadcast/multicast scheme that efficiently integrates scalable video coding, 3G broadcast, and ad-hoc forwarding so as to balance the system-wide and worst-case video quality of all viewers at 3G cell. Different from this work we consider (i) 3G links as multiple unicast transmissions, while in [24], multicast links are assumed, and (ii) network coding.…”

“…[28] proposes a cooperative IPTV system with pseudobroadcast to improve reliability. [29] proposes a system, in which a group of smartphone users (which are connected to the Internet via LTE links) help each other for error correction: base stations broadcast packets as in [24]. Although Multimedia Broadcast Multicast Services (MBMS) are provisioned for LTE [1], they are currently not implemented.…”

Abstract-Video applications are increasingly popular over smartphones. However, in current cellular systems, the downlink data rate fluctuates and the loss rate can be quite high. We are interested in the scenario where a group of smartphone users, within proximity of each other, are interested in viewing the same video at the same time and are also willing to cooperate with each other. We propose a system that maximizes the video quality by appropriately using all available resources, namely the cellular connections to the phones as well as the device-todevice links that can be established via Bluetooth or WiFi. Key ingredients of our design are: (i) the cooperation among users, (ii) network coding, and (iii) exploiting broadcast in the mobileto-mobile links. Our approach is grounded on a network utility maximization formulation of the problem. We present numerical results that demonstrate the benefit of our approach, and we implement a prototype on android phones.

“…To mitigate the aforementioned effect, the notion of device-to-device (D2D) communications [14] is proposed as a promising technique for 5G. Taking advantages of the potentially more reliable short-range communications [14], devices are allowed to transmit to each other coded packet resulting in an increase in performance [15][16][17][18].…”

This paper studies the delay reduction problem for instantly decodable network coding (IDNC)-based device-todevice (D2D) communication-enabled networks. Unlike conventional point-to-multipoint (PMP) systems in which the wireless base station has the sufficient computation abilities, D2D networks rely on battery-powered operations of the devices. Therefore, a particular emphasis on the computation complexity needs to be addressed in the design of delay reduction algorithms for D2D networks. While most of the existing literature on IDNC directly extend the delay reduction PMP schemes, known to be NP-hard, to the D2D setting, this paper proposes to investigate and minimize the complexity of such algorithms for battery-powered devices. With delay minimization problems in IDNC-based systems being equivalent to a maximum weight clique problems in the IDNC graph, the presented algorithms, in this paper, can be applied to different delay aspects. This paper introduces and focuses on the reduction of the maximum value of the decoding delay as it represents the most general solution. The complexity of the solution is reduced by first proposing efficient methods for the construction, the update, and the dimension reduction of the IDNC graph. The paper, further, shows that, under particular scenarios, the problem boils down to a maximum clique problem. Due to the complexity of discovering such maximum clique, the paper presents a fast selection algorithm. Simulation results illustrate the performance of the proposed schemes and suggest that the proposed fast selection algorithm provides appreciable complexity gain as compared to the optimal selection one, with a negligible degradation in performance. In addition, they indicate that the running time of the proposed solution is close to the random selection algorithm.

SummaryRecent research works have shown much interest in incorporating ad hoc networks with a cellular network to improve the data dissemination. The primary challenge of disseminating data over a hybrid network is to select the mode of operation between the cellular and ad hoc interfaces effectively. This work proposes Adaptive Data Dissemination (ADD) algorithm that enables the nodes to switch between the cellular and ad hoc interfaces and reduces the burden of the base station without degrading the communication efficiency. The proposed algorithm partitions the entire network into small clusters and selects the cluster head for each cluster based on the link‐worth function. This algorithm divides the transmission range of a base station into two regions such as interior and exterior. The interior region is nearer to the base station, while the exterior constitutes the border region of the base station's coverage area. The cluster heads in the interior region choose the cellular mode and retrieve the data from the base station directly. The cluster head in the exterior region initially chooses the ad hoc mode and later on chooses the cellular mode in the unavailability of demanding data in the neighboring cluster. The ADD algorithm does not allow the same node to act as a cluster head for a long time as the energy will get drained‐off quickly. Therefore, the proposed approach dynamically exchanges the role of the cluster head with the cluster members based on the link‐worth function. The base station deals only with the cluster heads in the interior range, and hence, minimizing the resource consumption at the base station. Nodes exchange as many chunks as possible using ad hoc links to reduce cellular network usage. The success of the proposed approach is evaluated using NS2 simulation.
