Indoor navigation is gaining an increasing interest among researchers in many domains. In many cases users need to orient quickly in complex environments, which is not always the target of current routing algorithms. The paper reviews current indoor pathfinding approaches and discusses some of the limitations. In order to support a natural movement in buildings, typically for emergencies, we pu...

The paper shows a simple technique which saves some edge tests in the walking algorithm for point location. The walking technique does not achieve the logarithmic per point complexity of the location-datastructure-based methods but does not need any auxiliary data structure and is very simple to implement, therefore, it is very popular in practice. The suggested idea did not bring a substantial...

For over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. Residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand,traditional buildings of Iran were designed according to ecological conditions...

Virtually all existing mobile robot localization techniques operate on a static map of the environment. When the environment changes (e.g., doors are opened or closed), there is an opportunity to simultaneously estimate the robot’s pose and the state of the environment. The resulting estimation problem is high-dimensional, rendering current localization techniques inapplicable. This paper propo...
