When considering disaster scenarios, reliable communication can save hundreds of lives. Due to destroyed infrastructure, Mobile Ad hoc Networks (MANETs) might be the only option for communication in such scenarios. However, such MANETs get partitioned frequently due to node movements resulting in intermittent connectivity. Delay Tolerant Networks (DTNs) are suitable to handle this. With the help of...
Stable and reliable communication is essential in disaster scenarios. Mobile Ad hoc Networks (MANETs) provide a network that is fast to setup and that works independently of possibly damaged infrastructure. This is important during disaster rescue and recovery missions. But single isolated MANETs are able to cover only a limited area. Therefore, it is necessary to interconnect these individual networks...
During disaster relief missions, it is essential to provide reliable communication between the different rescue teams and to the victims as well. Since a disaster is likely toe Mobile Ad hoc Networks (MANETs) are the best choice to reestablish communication. However, this type of networks has a major drawback, it can only cover relatively small areas. In large disaster sites, this results in creating...
Flooding, earthquakes, and other disasters are recent phenomenons which unfortunately occur more and more often. After such occurrences, the infrastructure is likely damaged, but rescue teams need to communicate with each other to plan the rescue missions. Mobile Ad hoc Networks (MANETs) are an efficient and cost-effective opportunity to establish communication, if no working infrastructure is available...
Intermittent connectivity is one major challenge for mobile nodes that move between different networks. Existing handover procedures are able to maintain the connectivity, if the communication ranges of the networks overlap. Otherwise, the connection will be lost. This is especially problematic for e-health applications, when emergency physicians are on the way to a patient and need to stay in contact...
Node mobility is one essential feature of mobile networks, especially for delay tolerant networks, where packet delivery is only possible through node movements. In mobile ad hoc networks, mobility adds new challenges to the protocol design. Therefore, realistic movement models are required to evaluate protocol performance. Usually, random node movement is considered for that but this kind of movement...
In disaster scenarios, communication systems usually consist of heterogeneous nodes and damaged infrastructure. Communication is important for rescue teams and victims as well but a serious problem because normal network systems like wired or mobile radio Internet could be unreliable or simply not available. To deal with these problems, much effort has been spent to mobile ad hoc networks (MANETs)...
Our paper proposes a new quality of service concept for smart home services. We assume that every flat in a house has its own smart computer to perform local services and acts as an interface for the different sensors and actors inside the flat. These smart computers are interconnected using a plain switched Ethernet infrastructure. A central server offers shared services for each user and a gateway...
