For an efficient usage of the sensor technology, several design factors (e.g., topology and sensing coverage) should be taken into account. In this paper, we focus on the underlying topology of sensor networks in two-dimensional environments and enhance a set of recently proposed graphs. The new enhanced graphs are referred to as the Derived Circles version 2 (DCα v2) graphs. We show that DCα v2 graphs...
Recently, different types of sensors have been developed to detect environmental changes (e.g., instability of the earth's crust) and to reduce the associated damage. For an efficient usage of the sensor technology, several design factors (e.g., topology and sensing coverage) should be taken into account. In this paper, we focus on the underlying topology of sensor networks in two-dimensional environments...
Sensor networks is a promising technology that can be used to avoid disasters such as fire, storm, etc. This technology needs to be improved in terms of several issues. In this paper, we focus on two issues: coverage and routing. For coverage problem, we introduce a new approach for obtaining a static covered network in the 3-D environment. This technique is referred to as the Chipset model. This...
