A comparative study on the implementation an efficient indoor navigation using smart devices in disaster situations

Abstract

In the last 10 years, scientists developed numerous indoor navigation systems but most of these systems are operated in robotic area. But due to the significant advance in technology, large number of smart devices developed. This phenomenon draws massive intention to human navigation topic. As a result, numerous indoor navigation systems for human have been developed and practiced in many research areas, for example marketing, asset management and tracking, security and so on. Disaster management is one of them, we can reduce casualties in emergency circumstances. In this paper, we propose an indoor navigation mechanism on smart devices combining map building and path planning techniques. The semantic map technique is adopted in this work to solve the map building task. This approach also comes in handy when deals with path planning task. Besides that, A* method is used to find the shortest path. The proposed method can be applied to help people in disaster situations.
