We consider the problem of autonomously controlling a fixed-wing aerial vehicle to visit a neighborhood of a pre-defined waypoint, and when nearby it, loiter around it. To solve this problem, we propose a hybrid feedback control strategy that unites two state-feedback controllers: a global controller capable of steering or transitioning the vehicle to nearby the waypoint and a local controller ...

The rapid growth of the Internet has made IP addresses a scarce resource. To get around this problem, today and in the foreseeable future, networks will be deployed with reusable-IP addresses (a.k.a. private-IP addresses) or IPv6 addresses. The Internet is therefore evolving into a collection of networks of heterogeneous address spaces. Such development jeopardizes the fundamental bi-directiona...

One of the operational requirements for unmanned aerial vehicles is the autonomous navigation and control along a given sequence of waypoints, or along a predefined trajectory. Existing autonomous navigation procedures are mostly done in 3D because of the stringent certification requirements for 4D flight and due to the complexity in coping with time of arrival at waypoints, whilst actual fligh...

Intermittently connected mobile networks (ICMNs) serve as an important network model for many critical applications. This paper focuses on a continuous ICMN model where the pair-wise meeting process between network nodes follows a homogeneous and independent Poisson process. This ICMN model is known to serve as good approximations to a class of important ICMNs with mobility models like random w...

The development of precision agriculture has gradually introduced automation in the agricultural process to support and rationalize all activities related field management. In particular, service robotics plays a predominant role this evolution by deploying autonomous agents able navigate fields while executing different tasks without need for human intervention, such as monitoring, spraying ha...

The purpose of this paper is to describe the design and implementation of an unmanned ground vehicle, called the Bearcat III, named after the University of Cincinnati mascot. The Bearcat III is an electric powered, three-wheeled vehicle that was designed for the Intelligent Ground Vehicle Competition and has been tested in the contest for 5 years. The dynamic model, control system, and design o...

Recent technological advances in portability, mobility support, and high speed wireless communications and users’ insatiable interest in accessing the Internet have fueled to development of mobile wireless networks. Internet-based mobile ad hoc network (IMANET) is emerging as a ubiquitous communication infrastructure that combines a mobile ad hoc network (MANET) and the Internet to provide univ...

The high-level contribution of this paper is to establish benchmarks for the minimum hop count per source-receiver path and the minimum number of edges per tree for multicast routing in mobile ad hoc networks (MANETs) under different mobility models. In this pursuit, we explore the tradeoffs between these two routing strategies with respect to hop count, number of edges and lifetime per multica...
