“…Reliable and efficiently-routed communication facilities are critical during emergency management. The aftermath of recent natural disasters (e.g., the Wenchuan earthquake in China and the Tsunami in Japan,) or terrorist attacks (e.g., the London attack and 9/11) has highlighted the fragilities and limitations of current infrastructure-based communication technologies [1]. In incident areas where pre-existing communication has been destroyed, emergency network communication (ENC) has to establish reliable and robust routes [2].…”

Wireless Mesh Networks (WMNs) employ hybrid distributed mobile networks with instant deployment and capabilities Such as: self_healing, self_organization and self_configuration. These abilities make WMNs a likely technology for incident communication. An Incident Area Network (IAN) requires a reliable and efficient routing path in an environment, where infrastructure-based communications have been destroyed. Routing awareness plays a significant part in this situation to deliver dynamic disaster facilities. Though, most of the proposed aware routing schemes do not entirely exploit the characteristics of WMNs. In this article, we propose a network environment-aware routing scheme for emergency response (NEARMesh) in WMNs, which employs a network routing information map to select the optimized path, based on cooperative consideration of route awareness information. This scheme is carried out and verified in NCTNus simulator. Imitation outcomes clearly display that the suggested scheme can enhance the network performance by maintaining a high delivery ratio with low latency while reducing the energy ingesting by minimizing network expenses.

When natural disasters or other large-scale incidents occur, obtaining accurate and timely information on the developing situation is vital to effective disaster recovery operations. High-quality video streams and high-resolution images, if available in real time, would provide an invaluable source of current situation reports to the incident management team. Meanwhile, a disaster often causes significant damage to the communications infrastructure. Therefore, another essential requirement for disaster management is the ability to rapidly deploy a flexible incident area communication network. Such a network would facilitate the transmission of real-time video streams and still images from the disrupted area to remote command and control locations.In this paper, a comprehensive end-to-end video/image transmission system between an incident area and a remote control centre is proposed and implemented, and its performance is experimentally investigated. In this study a hybrid multi-segment communication network is designed that seamlessly integrates terrestrial wireless mesh networks (WMNs), distributed wireless visual sensor networks, an airborne platform with video camera balloons, and a Digital Video Broadcasting-Satellite (DVB-S) system.By carefully integrating all of these rapidly deployable, interworking and collaborative networking technologies, we can fully exploit the joint benefits provided by WMNs, WSNs, balloon camera networks and DVB-S for real-time video streaming and image delivery in emergency situations among the disaster hit area, the remote control centre and the rescue teams in the field. The whole proposed system is implemented in a proven simulator. Through extensive simulations, the real-time visual communication performance of this integrated system has been numerically evaluated, towards a more in-depth understanding in supporting high-quality visual communications in such a demanding context.

Abstract-The wireless technology is one of the core components of mobile applications with mobility support at low deployment costs. Among these, Wireless Mesh Network (WMN) is one of the technologies that supports mobile users for un-disrupted, reliable data connectivity, provides high bandwidth even in areas, where access of such services is difficult. Additionally, it features capabilities like self-configuring, self-healing, and self-organizing. IEEE proposed a MAC standard for WMN enhancements named IEEE 802.11s for multi-hop networks. Within this standard, the mandatory routing protocol called Hybrid Wireless Mesh Protocol (HWMP) is proposed for efficient utilization of resources to achieve high bandwidth at MAC layer. To improve this protocol, a congestion avoiding protocol was proposed, which utilizes alternate paths just before the congestion state is reached. The proposed technique does not add any overhead, it utilizes congestion notification frame, which is already part of standard. This paper discusses simulation results of the proposed routing protocol against the existing HWMP protocol for packet delivery fraction, throughput and delay. The results indicate that the proposed technique significantly improves performance of IEEE 802.11s.
