Impromptu Deployment of Wireless Relay Networks: Experiences Along a Forest Trail

The authors are motivated by the problem of impromptu or as-you-go deployment of wireless sensor networks. As an application example, a person, starting from a sink node, walks along a forest trail, makes link quality measurements (with the previously placed nodes) at equally spaced locations, and deploys relays at some of these locations, so as to connect a sensor placed at some a priori unknown point on the trail with the sink node. In this paper, they report their experimental experiences with some as-you-go deployment algorithms. Two algorithms are based on Markov Decision Process (MDP) formulations; these require a radio propagation model.
