Distributed coverage aims to deploy a team of robots to move around a target area to perform sensing, monitoring, data collection, search, or distributed servicing tasks. This thesis investigates three variations of the coverage problem. First, we address the multi-robot single coverage of a target area. The aim is to guarantee that every accessible point in the area is visited in a finite time. The proposed algorithm supports heterogeneous robots having various maximal speeds, and is robust to robot failure

An area coverage control law in cooperation with reinforcement learning techniques is proposed for deploying multiple autonomous agents in a two-dimensional planar area. A scalar field characterizes the risk density in the area to be covered yielding nonuniform distribution of agents while providing optimal coverage. This problem has traditionally been addressed in the literature to date using locational optimization and gradient descent techniques, as well as proportional and proportional-derivative controllers. In most cases, agents' actuator energy required to drive them in optimal configur

This thesis presents two algorithmic implementations of multi-robot formation control for the area coverage problem. It uses a space exploration scenario, with a marsupial robot society, for tasks like mapping, habitat construction, etc. The solutions are though applicable to a wider range of applications, since area coverage is seen as one of the canonical problems in multi-robot application.<br/> <br/> <br/>Starting with an overview of multi-robot systems in space applications, both currently in use and planned for the near future, it then presents the two algorithms and their implementation

Success of Wireless Sensor Networks (WSN) largely depends on whether the deployed network can provide desired area coverage with acceptable network lifetime. In hostile or harsh environments such as enemy territories in battlefields, fire or chemical spills, it is impossible to deploy the sensor nodes in a predeter- mined regular topology to guarantee adequate coverage. Random deployment is thus more practical and feasible for large target areas. On the other hand, random deployment of sensors is highly susceptible to the occurrence of coverage holes in the target area. A potential solution fo

Swarm Intelligence (SI) is a young field of study from which solutions to complex problems have been proposed based on how some natural organisms (e.g. ants, bees and others) achieve many of their daily tasks through simple sets of interactions. This thesis proposes two models for area exploration and coverage based on SI principles. These two models present a novel approach based on the combination of: ants’ pheromones, in order to keep track of visited places; and bird flocks or fish schooling, so as to move and collaborate. An implementation of both models was done in order to simulate and

Mobile wireless sensor networks are not widely implemented in the real world, even after years of research carried out in this field.

This thesis presents a simulation-based study of different mobility models. The total area coverage that depends on the pattern of node movements is observed through simulations.

The emerging techniques of mobile GIS applications, its abilities and its implied limitations ofinternet connections is the main subject in this study. Many of the operations that mobile devicesuse are dependent on mobile internet connectivity. Therefore the potential for it in well connectedareas is great but how would they function in less connected areas? Mobile GIS, which is todaymostly used in devices as smart phones and tablets, has internet connectivity for uploading anddownloading files and other data. Mobile GIS is also dependent on location-based services thatenable the device to get

Yes<br>Sensing coverage and network connectivity are two of the most fundamental issues to ensure that there are effective environmental sensing and robust data communication in a WSN application. Random positioning of nodes in a WSN may result in random connectivity, which can cause a large variety of key parameters within the WSN. For example, data latency and battery lifetime can lead to the isolation of nodes, which causes a disconnection between nodes within the network. These problems can be avoided by using mobile data sinks, which travel between nodes that have connection problems
