Evacuation Route

Recent day In disastrous rescue mission has many challenges to Establishing a short and temporary communication system to provision disaster based communications and networking. This research paper main goal is Propagation of communication emergency messages to neighbors or people is reflected to deliver more prompt assistance than remote or distant rescue entities. The emergency communication service in order to improve communication range, victim localization and evacuation route planning. Since, the popularity of smart phones has been unprecedentedly increased. Thus increases the possibilities of successful receiving and recognizing SOS messages. SOS messages are generated by a code called as MORSE code. This research focus on to maintain and establish communication in situation of an disaster communication among a smartphone as a source and destination node like base station in case of absence. This communication has followed as one way communication from source to any destination inside an emergency region. To achieve this prime goal of this research is to take improvement of wireless communication of smartphones to establish and broadcast and forward the message from the source to rescue unit. In this case, to generating and establishing new communication client or victims and outside world, sending the emergency messages done over the wireless technology. Reestablishment of communication has in our prototype. This research has considered application, no hypothesis is made with respect to the reality of a complete and whole communication link among two commination nodes wishing to participate to communicate. Any possible node can opportunistically be used as a next hop, provided takes the message closer to the exact final destination. These features match the perception of opportunistic networking.

Potential Remedy

Evacuation planning is becoming crucial due to an increasing number of natural and human-created disasters over last few decades. One of the efficient ways to model the evacuation situation is a network flow optimization model. This model captures most of the necessities of the evacuation planning. Moreover, dynamic network contraflow modeling is considered a potential remedy to decrease the congestion due to its direction reversal property and it addresses the challenges of evacuation route planning. However, there do not exist satisfactory analytical results to this model for general network. In this paper, it is tried to provide an annotated overview on dynamic network contraflow problems related to evacuation planning and to incorporate models and solution strategies to them developed in this field to date.

Evacuation Route

Efficient evacuation planning is important for quickly navigating people to shelters during and after an earthquake. Geographical information systems are often used to plan routes that minimize the distance people must walk to reach shelters, but this approach ignores the risk of exposure to hazards such as collapsing buildings. We demonstrate evacuation route assignment approaches that consider both hazard exposure and walking distance, by estimating building collapse hazard zones and incorporating them as travel costs when traversing road networks. We apply our methods to a scenario simulating the 2016 Gyeongju earthquake in South Korea, using the floating population distribution as estimated by a mobile phone network provider. Our results show that balanced routing would allow evacuees to avoid the riskiest districts while walking reasonable distances to open shelters. We discuss the feasibility of the model for balancing both safety and expediency in evacuation route planning.
