This paper investigates the affect of pathloss and mobility in an urban environment on MANETs. Specifically, this investigation employs mobility and pathloss that resembles the mobility of pedestrians and pathloss in urban environments. We study the behavior of MANETs on a university campus and in the Paddington area of London England. The model utilizes ray tracing to provide realistic radio w...

Modern computer networks support interesting new routing models in which traffic flows from a source s to a destination t can be flexibly steered through a sequence of waypoints, such as (hardware) middleboxes or (virtualized) network functions (VNFs), to create innovative network services like service chains or segment routing. While the benefits and technological challenges of providing such ...

In this paper, a simplified aircraft system model is developed correctly emulating the nonlinear dynamics of complex aircraft models under closed-loop control. The simplified model is based on Dubins models used in optimization algorithms for trajectory control of multiple Unmanned Aeriel Vehicles (UAVs). Algorithms optimizing area coverage for reconnaissance based on UAV capabilities, fuel rem...

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Since not many MANETs are currently deployed, research in this area is mostly simulation based. Random Waypoint is the commonly used mobility model in these simulations. Random Waypoint is a simple model that may be applicable to some scenarios. However...

Network operators want additional functionality from the networks they manage. The current approach to add functionality is to deploy middleboxes. Unfortunately middleboxes raise concerns regarding robustness, correctness, and efficiency due to their need to be deployed at chokepoints. This paper provides some initial thoughts of solving the middlebox problem in an architectural way. We believe...

On-line motion planning in unknown environments is a challenging problem as it requires (i) ensuring collision avoidance and (ii) minimizing the motion time, while continuously predicting where to go next. Previous approaches to on-line motion planning assume that a rough map of the environment is available, thereby simplifying the problem. This paper presents a reactive on-line motion planner,...

Fire monitoring and early detection are critical tasks in which Unmanned Aerial Vehicles (UAVs) commonly employed. This paper presents a system to plan the drone patrolling schedule according real-time estimation of fire propagation index that is derived from satellite data, such as Normalized Difference Vegetation Index (NDVI) measurement Digital Elevation Model (DEM) surveilled area. The prop...

This paper presents a perception-aware path planner for active SLAM in dynamic environments using micro-aerial vehicles (MAV). The “Next-Best-View” (NBVP planner) is combined with an loop closing, which called the Active Loop Closing Planner (ALCP planner). proposed to avoid both static and obstacles unknown while reducing uncertainty of system further improving accuracy localization. First, re...
