This paper describes an implementation of a wireless mobile ad hoc network with radio nodes mounted at fixed sites, on ground vehicles, and in small (10kg) UAVs. The ad hoc networking allows any two nodes to communicate either directly or through an arbitrary number of other nodes which act as relays. We envision two scenarios for this type of network.

This paper presents a method for reliably collecting data events from sensors and forwarding the data via a MANET to sensor monitoring stations located on an external network. A the core is a MANET concept that consists of ground and unmanned aircraf nodes. Unmanned aircraf enable a model whereby widely-spaced sensors are intermittently connected to the(More)
Electronic chaining is the formation, and maintenance, of a linked communication chain that maximizes the endto-end throughput using a cooperative team of mobile robotic relays. For this paper, an optimal communication chain is defined using the signal-to-noise ratio (SNR) of the communication links along the chain. By using the SNR of the individual(More)
In this paper we investigate the phase transitions between different modes of controlled mobility in wireless ad hoc networks. The transmission of data between two nodes can be performed by one of three methods in a mobile ad hoc network: direct transmission between nodes; multi-hop relaying through intermediate nodes; and data ferrying through a node that(More)
This paper introduces the Radio Leashing Problem and presents a control system to solve the problem for a single unmanned aircraft. The leashing problem as presented in this paper is to electronically tether an unmanned vehicle to one ore more radio nodes so that it may act as a communication repeater between them in a multi-hop network. The method proposed(More)
