“…This yields a more effective bandwidth utilization during disconnections and allows a streaming session to resume (rather than restart) upon reestablishment of connectivity, but mobility is not exploited. An approach that does this, is MOMENTUM, by Cabrero et al [65]. In an overlay network, session nodes are used as relays and can be used to forward streaming toward the destination with no end-to-end connectivity.…”

“…Again, this value is nevertheless dependent on the targeted scenario, which renders many of the results unfeasible for comparison. For similar solutions, speed should be seen in relation to node density, and although high speeds are usually associated with the challenges of increased dynamicity (e.g., during re-routing and maintaining a consistent view of topology), many caching, replication and store-carry-forward solutions can benefit from a high mobility, (e.g., [65]). During comparison, it should be considered that for some metrics, increasing the node speed is equivalent to increasing the duration of the simulation.…”

Developments in mobile devices and wireless networking provide the technical platform for video streaming over mobile ad hoc networks (MANETs). However, efforts to realize video streaming over MANETs have met many challenges, which are addressed by several different techniques. Examples include cross-layer optimization, caching and replication, and packet prioritization. Cross-layer optimization typically leverages multiple description video coding and multipath routing to provide the receiver(s) sufficient video quality. Caching and replication add tolerance to disruptions and partitioning. In this paper, we identify the challenges of realizing video streaming over MANETs, and analyze and classify the proposed techniques. Since 65 % of the identified involve cross-layering design, we study the distribution of joint optimization and parameter exchanges. Due to the importance and complexity of evaluating the techniques, we analyze the common methods, indicating that the research domain suffers from a problem of comparability.

“…To name a few: the application in [10] generates maps from disaster areas using a DTN; YouSoS [11] is another application that distributes multimedia content with the aid of victims; MOMENTUM [12] aims to distribute video merging MANET and DTN paradigms; and the work presented in [13] assists in the process of triage. These are just a few examples of the many that exist.…”

Abstract-Ad-hoc networks have long been studied as an ideal technology to provide communications in emergency operations when network infrastructures are not available. Nevertheless, this area has not yet delivered enough mature technologies or working prototypes. We suspect that, among other issues, this is due to a lack of understanding of this application domain that forces researchers to make too many assumptions. One of those concerns is the mobility of network nodes. This paper describes, analyzes and simulates the mobility traces of a fire department during 30 wildfires. The analysis shows interesting insights into the communication range and the type of network in these scenarios. For instance, multi-hop routes are unlikely, so the network behaves like a Delay-Tolerant Network. In addition, the simulation results present a clear image of the network performance under different circumstances that can be used to design applications. We found that the network capacity is low due to the sparse network connectivity. Moreover, the buffer size has a much bigger impact on data delivery than the delay-tolerant routing protocol selected. We think that these are valuable insights and that the traces constitute an important asset for the research community.

“…Research was conducted within the areas of mobile streaming services solutions. The study reveals that although there are various papers on using JAVA ME to developed such solutions within the domain of mobile streaming services [4,5,6,7,8], there is little research focusing on the use of a JAVA ME based solution in Wi-Fi environments using different voice codec for mobile voice streaming. However, the work reported in [4] presents a new system that provides audio messages streamed to mobile phones using RTSP even if formerly the mobile phone does not support this protocol.…”

Mobile Streaming is a very attractive multimedia service that has many applications; in this paper a model of a mobile voice message (MVM) service has been proposed using JAVA ME, whose aim is to create and deliver streaming of voice messages to mobile phones. The MVM model is based on a layered client-server architecture. MVM is designed to operate in wireless data networks, such as Wi-Fi, GPRS and 3G, where mobile clients access information sources via wireless channels. Emerging JAVA ME technology is discussed as an efficient platform for providing a mobile client solution. Based on this concept, a prototype for a mobile voice message application was developed, implemented and tested using different audio codecs. The proposed model has been evaluated and validated experimentally and the results shows that AMR codec can outperform than PCM codec in terms of bandwidth utilisation .
