An Efficient Gateway Routing Scheme for Disaster Recovery Scenario

Abstract

Natural disaster can strike at any time and in any place. Once it has occurred, it can ruin large regions, cause damage to houses and buildings, and destroy physical communication infrastructure. Therefore, a network backup is required in the disaster recovery area because victims will want to contact their important person to update the current situation as soon as possible. A mobile ad hoc network (MANET) is a collection of mobile devices that dynamically communicate with each other without any physical infrastructure. This feature offers a solution for communication problems during disaster recovery and keeping communication in disaster recovery areas alive. In this paper, an efficient routing scheme (GWRS) is proposed to eliminate the congestion that occurs when people in a disaster recovery area want to connect to a network. This new scheme provides a flexible and feasible approach in determining the best route. The routing scheme will simplify the selection of routes and prevent nodes from broadcasting packets to the entire network. In addition, this scheme eradicates any redundant nodes in each level of the routing table. These schemes have been simulated in a realistic environment of disaster recovery area. Ad-Hoc On-Demand Distance Vector (AODV) and Destination Sequenced Distance Vector (DSDV) routing schemes were also selected to be simulated in the same environment because these schemes show the best performance for reactive and proactive categories in emergency scenarios. Then, the performance of the proposed scheme was compared to these two schemes and evaluated through computer simulations using OMNET++ simulation tools. The results have shown that our proposed method has better results.

Enhancing the Fault Tolerance of a Multi-Layered IoT Network through Rectangular and Interstitial Mesh in the Gateway Layer

“…Every gateway will take a modest hit thanks to the traffic handling strategy provided by Mahiddin and Sarkar (2019) [48]. In the event that the primary gateway breaks, Minh et al (2014) [49] suggested using an OEMAN technique to designate one mobile device as a backup access point.…”

Heterogeneous wireless IoT architecture for natural disaster monitorization

“…Some previous works contribute to solve the congestion of the traffic [8], or highlight the need of organizing a disaster recovery plan for each area [9]. While there are solutions based on the virtualization of cloud services [10], other solutions desegregate the network to minimize equipment failure risks and propose protection approaches for fast recovery of network nodes after disaster happens [11].…”

A review on mobility models in disaster area scenario

“…Figure 1 MANET operations [3] MANET can be considered as a promising solution, especially in an unfavourable conditions such as disaster response and recovery where fixed infrastructure is unavailable due to the aftermath of the disaster [4]. The communication network can be recovered within a short time, making delays and errors in SAR operations and mission critical to be minimized.…”

“…The communication network can be recovered within a short time, making delays and errors in SAR operations and mission critical to be minimized. Thus, the MANET can be considered as one of the best approach for SAR operations due to its rapid deployment, making the rescue teams to immediately respond to the victims call for help upon receiving [4,5]. The objectives to focus the current aspects in this area are as under: 1.…”
