Disaster management is management of tasks involving responses to emergencies and methods of devising recovery strategies from havocs caused by nature. It assumes paramount importance now as the human surrounding has enormously become unpredictable owing to natural or man-made disasters. Consequence of disaster can be reduced by broadcasting of disaster alert to a defined radius that could be affected by the disaster. The objective of disaster management is to ensure energy economical and reliable communication that is resilient to network topology changes within the area. Vehicular ad hoc network (VANET) is efficiently utilized to transfer the disaster alert information. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication is used for disseminating the disaster alert message. This study proposes an effective data acquisition from the disaster location, data dissemination to the neighbouring zones and disaster management using VANET technology.

The paper presents Vehicular Ad Hoc Network (VANET) system based on an analysis of the movement of a motorcade in an emergency situation. This analysis seeks to answer the question: when and under what conditions Emergency Message (EM) sent by Vehicle-to-Vehicle (V2V) system reaches the final target to help in preventing of serious accidents, such as multi-vehicle collisions. The model of calculation based on the key principles of vehicle braking enables finding the time to possible collision and the residual velocity of the vehicle. In the calculations, the average values of the driver’s reaction time are accepted; in addition, a sent emergency message is considered to be free of interference. Upon choosing different road and driving conditions, it is found what vehicle of the motorcade stops before the possible obstacle on emergency braking. The performance of vehicles with and without VANET system is compared.

In recent years, WiFi offloading provides a potential solution for improving ad hoc network performance along with cellular network. This paper reviews the different offloading techniques that are implemented in various applications. In disaster management applications, the cellular network is not optimal for existing case studies because the lack of infrastructure. MANET Wi-Fi offloading (MWO) is one of the potential solutions for offloading cellular traffic. This word combines the cellular network with mobile ad hoc network by implementing the technique of Wi-Fi offloading. Based on the applications requirements the offloading techniques implemented into mobile-to-mobile (M-M), mobile-to-cellular (M-C), mobile-to-AP (M-AP). It serves more reliability, congestion eliminated, increasing data rate, and high network performance. The authors also identified the issue while implementing the offloading techniques in network. Finally, this paper achieved the better performance results compared to existing approaches implemented in disaster management.

Given a scenario of Vehicle Ad hoc Network (VANET), this paper presented a GIS-Based routing (GBR) strategy to resolve frequent reconstruction caused by rapid topology changes. Due to the use of road information based on GIS, the protocol can evade permanent or temporary topology holes respectively which frequently occurred in the city scenario. Simulation results showed new routing protocols could achieve better performance in packet delivery ratio and proved GBR’s lower routing overhead, as well as it is better performances in high mobility, compared with DSR in urban vehicle environment.

SummaryA robust exchange of messages between vehicles via radio communication represents a key problem of vehicular ad hoc network (VANET) research. Environmental influences and the multitude of communicating nodes result in challenging communication conditions that have to be taken into account when assessing the potential benefit of VANETs for traffic safety and efficiency applications. In this paper we discuss an appropriate modeling of three influencing factors on the communication behavior to establish a basis for credible simulation results. In detail, we analyze the effects of fast-fading, capturing, and cumulative noise on vehicular communications and illustrate their considerable influence on a simulation's outcome. As a second contribution, we provide an empirical model for the probability of packet reception that is based on the proposed simulation methodology. The model thus allows to determine credible simulation results without being dependent on the complexity of detailed simulations. The saved computational effort facilitates the assessment of VANETs in large-scale scenarios and the consideration of communication specifics in the design process.
