Accurate situational information about damage, resource needs, available resources etc., in the affected areas help the disaster management agencies in proper damage and need assessment and prepare suitable resource deployment plan. Crowdsourcing has become a popular approach for information collection where open crowds of people share multimodal situational information (text, images, audio, video etc.) about any event through social media posts. However, the authenticity and reliability of such posts are still debatable. Gathering situational data directly from the affected community (community-sourcing) can supplement social media posts to generate effective insights. In this paper, we attempt to design and develop a multiplatform disaster management information system where both social media-based crowdsourcing and community sourcing techniques are used to accumulate location-specific situational information. Subsequently, a coherent picture of the disaster situation is evolved through the integration of these local snapshots. Here, we explore how community participation, in the context of disaster management, can be enhanced through collaborative knowledge transaction, which eventually will lead towards the development of a resilient community. A field trial of our system is conducted involving a remote village community at Namkhana, West Bengal.

Moreover, information about resource needs of far-flung areas get rarely permeated owing to the disruption of cellular and other communication infrastructure, leading to a huge gap in perception about the actual needs in those areas. Therefore, a dynamic need assessment mechanism is essential to stay abreast of the actual situation. Movements of volunteers and relief workers are governed by two dominant characteristics of human mobility - spatial locality and spatial regularity. In this paper, we make use of such mobility characteristics to propose a knowledge sharing based approach for dynamic assessment of post disaster resource needs using a smart-phone based delay tolerant network (DTN). The proposed technique caters to the objective of bridging the gap in perception about actual resource needs.

However, it has also been shown that the success of multipath routing in ad hoc wireless network depends on network topology and channel characteristics can severely limit the gain offered

As mentioned earlier, these assessed needs are required to be transmitted and accumulated at the control station for maintaining a fully functional relief chain.

While demand signifies the amount of resource required, utility represents the exigency of that requirement. Due to lack of, or imprecise need assessments immediately after a disaster, relief requirements are generally set up based on coarse estimates by logisticians regarding what people would normally need. The effectiveness of this estimation depends on the competencies and experience of the logistician in control, often leading to impromptu allocation of typically scarce emergency resources. Thus, forecasting the exact demand and enumerating the correct utility of emergency resources are inevitable.

The objects that are monitored can be personnel, equipment or an environmental condition. The architecture also enables the control of asset utilization by triggering actuators. Active RFID tags, combined with sensors and actuators, form a wireless mesh network based on IEEE 802.15.4. We develop a new routing algorithm oriented for these tracking applications where the network is sparse but comprises of extended legs. We elaborate a test-bed implementation for tracking underground miners and equipment along with monitoring the underground environment for possible emission of toxic gases.

Since real time on-line data about the safety and security parameters are not available, there is minimal scope to take any prior preventive measure to avoid any kind of safety & security hazards. Since identification of any forthcoming crisis requires current information, and such information must be communicated in real-time, therefore the need arises for an integrated ubiquitous communication network for industrial safety, security and its management that provides efficient, reliable, secure exchange and processing of relevant information. The objective of the paper is to analyze the impact of using our Real-Time Tracking, Sensing and Management System using Active RFID, Sensors and Wireless Mesh Network for improving industrial safety & security. We will discuss a unified ubiquitous framework for both object visibility and environment visibility of an enterprise through real-time tracking and moni...

However, use of Twitter and Facebook by victims, first responders and others generates information that is varied, unstructured and unreliable. On the other hand, NGOs, operating in the disaster area, are often involved in intra-organizational communication using messaging apps like WhatsApp, and their group interactions can help in gathering meaningful data for situational analysis and need assessment. Our focus is to automate the process of filtering relevant information, query-based clustering of pertinent information from a WhatsApp group conversation of a specific volunteer group, so that situation analysis and need assessment can be done more rapidly. We have evaluated our scheme using WhatsApp chat log of a medical volunteer group in two post-disaster scenarios and concluded that it can provide valuable insights about region-specific resource requiremen...

Protecting these resources and workers against possible accidents and maximizing their utilization through real time location monitoring and control can improve the mine safety and productivity to a great extent. At the same time, the sensitive areas of mining premises must be automatically protected against unauthorized intrusion to cope up with possible security hazards.
