This work preliminarily introduces an up to date measurement-driven examination of the spatial characteristics of network resource usage. The data set used is from a large nationwide 3G cellular network comprised of several thousand base stations. Firstly, we discuss our data set and how it can be appropriately used. Next, we examine the spatial correlation between base stations in terms of rad...

This article describes a concept of an autonomous landing system of UAV (Unmanned Aerial Vehicle). This type of device is equipped with the functionality of FPV observation (First Person View) and radio broadcasting of video or image data. The problem is performance of a system of autonomous drone landing in an area with dimensions of 1m × 1m, based on CCD camera coupled with an image transmiss...

To enable the drone delivery service in a remote area, this paper considers approach of deploying charging stations and collaborating with public transportation vehicles. From warehouse which is far from customer, takes some vehicles to reach position close area. When customer unreachable where leaves vehicle, swaps battery at station. The focus deployment stations. We propose new model charact...

With the rapid development of high-speed railways, demands on high mobility wireless communication increase greatly. To provide stable and high data rate wireless access for users in the train, it is necessary to properly deploy base stations along the railway. In this paper, we consider this issue from the perspective of channel service which is defined as the integral of the timevarying insta...

Imagine an island modeled as a simple polygon P with n vertices whose coastline we wish to monitor. We consider the problem of building minimum number refueling stations along boundary in such way that drone can follow polygonal route enclosing without running out fuel. A fly maximum distance d between consecutive and is restricted move either or its exterior (i.e., over water). present algorit...

Just as the mobile phone allowed developing countries to leapfrog technology in personal communication, the delivery drone has the potential to have the same effect on traditional transportation infrastructure. Inaccessible roads no longer will prevent delivery of blood, medications or other healthcare items. This paper reviews the current status of innovative drone delivery with a particular e...
