The key features of computer networks available for a disaster situation are reliable, fault tolerance, and self-configurable. Therefore, using a wireless mesh network for disaster prevention and recovery system has gained much attention from the research community in the last decades. In addition, from the practical aspects of the network infrastructures of the disaster system, we should assume the core capabilities such as wireless connectivity in a wide range, ease of use, and low cost so on. In this paper, we propose an interface mode assignment method for reconstructing a route from an isolated router to a gateway (GW) router in a wireless mesh network based on IEEE 802.11 infrastructure mode after a disaster occurrence. The proposed method assigns an adequate mode to each interface in an isolated router to recover the network reachability in a distributed manner. Simulation results show the effectiveness of the proposed method via two different scenarios.

“…One self-organizing traffic light system [ 11 ] possesses global synchronization achieved adaptively through local interactions between cars and traffic lights and generates flexible green-light waves on demand, unlike centralized legacy traffic lights systems. Apart from a self-organizing distributed concept in these various domains, there is research into configuring a network infrastructure with a self-organizing concept [ 12 ]. The research suggests a self-organizing reconfiguration method of opportunistic infrastructure-mode in ad-hoc WiFi networks.…”

Indoor location-based services (iLBS) are extremely dynamic and changeable, and include numerous resources and mobile devices. In particular, the network infrastructure requires support for high scalability in the indoor environment, and various resource lookups are requested concurrently and frequently from several locations based on the dynamic network environment. A traditional map-based centralized approach for iLBSs has several disadvantages: it requires global knowledge to maintain a complete geographic indoor map; the central server is a single point of failure; it can also cause low scalability and traffic congestion; and it is hard to adapt to a change of service area in real time. This paper proposes a self-organizing and fully distributed platform for iLBSs. The proposed self-organizing distributed platform provides a dynamic reconfiguration of locality accuracy and service coverage by expanding and contracting dynamically. In order to verify the suggested platform, scalability performance according to the number of inserted or deleted nodes composing the dynamic infrastructure was evaluated through a simulation similar to the real environment.

“…As storage device we have used the internal built-in flash storage. For peer-to-peer networking we have used the built-in WiFi only: the device alternates between WiFi AP mode and WiFi Client mode in a random fashion to create dynamic WLANs and discover nearby peers [8]. This choice is due to the fact that alternative peer-to-peer approaches such as WiFi-direct and Bluetooth either require mandatory user-assisted device pairing or device rooting, while we want to share files in a transparent opportunistic way that also works in unmodified devices.…”

ShAir is a middleware infrastructure that allows mobile applications to share resources of their devices (e.g., data, storage, connectivity, computation) in a transparent way. The goals of ShAir are: (i) abstracting the creation and maintenance of opportunistic delay-tolerant peer-to-peer networks; (ii) being decoupled from the actual hardware and network platform; (iii) extensibility in terms of supported hardware, protocols, and on the type of resources that can be shared; (iv) being capable of self-adapting at run-time; (v) enabling the development of applications that are easier to design, test, and simulate. In this paper we discuss the design, extensibility, and maintainability of the ShAir middleware, and how to use it as a platform for collaborative resource-sharing applications. Finally we show our experience in designing and testing a file-sharing application.
