Coverage area prediction for HDTV

Proceedings of APCCAS'94 - 1994 Asia Pacific Conference on Circuits and Systems, 2002
A coverage area prediction method developed in TL (Telecommunication Laboratories) is introduced. The program uses a simple method to predict the signal interference and coverage area automatically and quickly. This technique helps us to re-allocate the site and frequency of radio stations efficiently, especially useful for the advent of HDTV.

Coordination of multiple vehicles for area coverage tasks

2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007
Area coverage operations such as plowing a field or mowing a lawn can be performed faster if multiple vehicles are involved. To use a team of automated vehicles safely and effectively they must be coordinated to avoid collisions and deadlock situations.

Multi-robot area coverage with limited visibility

International Joint Conference on Autonomous Agents and Multiagent Systems, 2010
We address the problem of multi-robot area coverage and present a new approach in the case where the map of the area and its static obstacles are known and the robots have a limited visibility range. The proposed method starts by locating a set of static guards on the map of the target area and then builds a graph called Reduced-CDT, a new environment ...

Radio Broadcast Coverage of City Areas

Transactions of the American Institute of Electrical Engineers, 1926
l. Radio broadcasting involves a system of electrical distribution in which dependent relations exist between the transmitting station, the transmitting medium and the receiving station. 2. The attenuation and fading which attend the spreading out of broadcast waves are considered.

A survey on area coverage in wireless sensor networks

2014 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2014
In recent years, Wireless Sensor Networks (WSNs) have gained much attention because of its varying applications from catastrophic region to industrial and household region. In few applications, sensors are deployed in extreme environmental conditions. Hence, node access is not possible in that scenario.

Coverage area management for wireless sensor networks

International Journal of Network Management, 2006
AbstractIn this work, we present a self‐management service for Wireless Sensor Networks (WSNs) that automatically controls the network redundancy. Based on a density control function, this service improves the monitoring potential of the sensor nodes. Our simulation experiments show that this self‐management service provides good and lasting coverage ...

Improving area coverage by reversible object pushing

2011 15th International Conference on Advanced Robotics (ICAR), 2011
This article presents the implementation of an innovative safety module for a robot control architecture. It applies the principle of reversibility to assess intrinsic safety of actions and to adapt robot's behavior. The underlying idea is that all reversible actions are intrinsically safe.

Homogeneous Hierarchical Composition of Areas in Multi-robot Area Coverage

2007
Multi-robot area coverage poses several research challenges. The challenge of coordinating multiple robots' actions coupled with the challenge of minimizing the overlap in coverage across robots becomes even more complex and critical when large teams and large areas are involved.

Area coverage maximization in service facility siting

Journal of Geographical Systems, 2009
Traditionally, models for siting facilities in order to optimize coverage of area demand have made use of discrete space representations to efficiently handle both candidate facility locations and demand. These discretizations of space are often necessary given the linear functional forms of many siting models and the complexities associated with ...

On area coverage reliability of wireless sensor networks

2011 IEEE 36th Conference on Local Computer Networks, 2011
In this paper we consider wireless sensor networks (WSNs) whose nodes can fail independently of each other during normal operation. For successful operation, a network is required to provide sensing coverage of an aggregate area that exceeds a given application-specific coverage requirement.
