Video Dissemination over Hybrid Cellular and Ad Hoc Networks

Abstract We study the problem of disseminating videos to mobile users by using a hybrid cellular and ad hoc network. In particular, we formulate the problem of optimally choosing the mobile devices that will serve as gateways from the cellular to the ad hoc network, the ad hoc routes from the gateways to individual devices, and the layers to deliver on these ad hoc routes. We develop a Mixed Integer Linear Program (MILP)-based algorithm, called POPT, to solve this optimization problem. We then develop a Linear Program (LP)-based algorithm, called MTS, for lower time complexity. While the MTS algorithm achieves close-to-optimum video quality and is more efficient than POPT in terms of time complexity, the MTS algorithm does not run in real time for hybrid networks with large numbers of nodes.

Abstract Con… We, therefore, propose a greedy algorithm, called THS, which runs in real time even for large hybrid networks. We conduct extensive packet-level simulations to compare the performance of the three proposed algorithms. We found that the THS algorithm always terminates in real time, yet achieves a similar video quality to MTS. Therefore, we recommend the THS algorithm for video dissemination over hybrid cellular and ad hoc networks.

Existing System Mobile devices, such as smartphones and tablets, are getting increasingly popular, and continue to gener¬ate record-high amount of mobile data traffic. For example, a Cisco report indicates that mobile data traffic will increase 39 times by Sixty six percent of the increase is due to video traffic [1]. Unfortunately, existing cellular networks were designed for unicast voice services, and do not natively support multicast and broadcast. Therefore, cellu¬lar networks are not suitable for large-scale video dissemi¬nation. This was validated by a measurement study, which shows that each HSDPA cell can only support up to six mobile video users at 256 kbps [2]. Thus, disseminating videos to many mobile users over cellular networks could lead to network congestion and degraded user experience.

CONCLUSION We studied the problem of optimally leveraging an auxiliary ad hoc network to boost the overall video quality of mobile users in a cellular network. We formulated this problem as an MILP problem to jointly solve the gateway selection, ad hoc routing, and video adaptation problems for a global optimum schedule. We proposed three algorithms: 1) an MILP-based algorithm, POPT, 2) an LP- based algorithm, MTS, and 3) a greedy algorithm, THS. Via packet-level simulations, we found that neither POPT nor MTS scale to large hybrid networks.
