We design, implement, and evaluate a middleware system, HybCAST, that leverages a hybrid cellular and ad hoc network to disseminate rich contents from a source to all mobile devices in a predetermined region. HybCAST targets information dissemination over a range of scenarios (e.g., military operations, crisis alerting, and popular sporting events) in which high reliability and low latency are critical and existing fixed infrastructures such as wired networks, 802.11 access points are heavily loaded or partially destroyed. HybCAST implements a suite of protocols that: (i) structures the hybrid network into a hierarchy of two-level ad hoc clusters for better scalability, (ii) employ both data push and pull mechanisms for high reliability and low latency dissemination of rich content, and (iii) implement a near-optimal gateway selection algorithm to minimize the transmission redundancy. To demonstrate its practicality and efficiency, we have implemented and deployed the HybCAST middleware on several Android smartphones and an in-network Linux machine that acts as a dissemination server. The system is evaluated via real experiments using a UMTS network and extensive packet-level simulations. Our experimental results from a live network show that HybCAST achieves 100% reliability with shorter latencies and lower overall energy consumption. Simulation results confirm that HybCAST outperforms other state-of-the-art systems in the literature. For example, HybCAST exhibits a 5 times reduction in the dissemination latencies as compared to other hybrid dissemination protocols, while its energy consumption is a third of a cellular-only dissemination system. Furthermore, the simulation results demonstrate that HybCAST scales well and maintains good performance under varying numbers of mobile devices, diverse content sizes, and device mobility.

“…Some works use one cellular multicasting channel instead of unicasting the content to each MT. However, the multicasting rate is limited by the MTs with bad channel conditions, and consequently, the base station (BS) multicasts the content to the MTs with good channel conditions that forward the content to the other MTs using ad hoc connections [4], [5]. Others propose the division of the content into several small parts to be transmitted to some MTs using the cellular channels, then the MTs exchange the received parts via local ad hoc networks [6].…”

Increasing the capacity of wireless cellular networks is a major concern for network operators. We address the problem of offloading the cellular network via assistance from the mobile terminals to receive an on-demand common content from the base station. The base station unicasts the content to selected mobile terminals that either unicast or multicast it to other mobile terminals over local ad hoc networks. We formulate the resulting problems as linear mixed integer optimization problems that minimize the required number of cellular channels subject to energy consumption constraints at the mobile terminals side. Performance results demonstrate that the achieved gains in terms of reduction of cellular channels depend significantly on the mobile terminals' energy consumption constraints. For one hop ad hoc networks, significant reduction gains reaching up to 90% and 50% for multicasting and unicasting, respectively, can be achieved, if only 5% of the mobile terminals' battery level can be spent on cooperation. More gains can be achieved with multihop ad hoc networks, however, at the cost of a higher computationally complex solution.

Video-on-demand service in wireless networks is one important step to achieving the goal of providing video services anywhere anytime. Typically, carrier mobile networks are used to deliver videos wirelessly. Since every video stream comes from the base station, regardless of what bandwidth sharing techniques are being utilized, the media stream system is still limited by the network capacity of the base station. The key to overcome the scalability issue is to exploit resources available at mobile clients in a peer-to-peer setting. We observe that it is common to have a carrier mobile network and a mobile peer-topeer network co-exist in a wireless environment. A feature of such hybrid environment is that the former offers high availability assurance, while the latter presents an opportunistic use of resources available at mobile clients. Our proposed video-on-demand technique, PatchPeer, leverages this network characteristic to allow the video-on-demand system scale beyond the bandwidth capacity of the server. Mobile clients
