Evaluation of a Framework for Measuring Efficency in Opportunistic Ad-hoc Networks

Opportunistic networks are the manifestation of wireless ad-hoc networks where there is no continuous end-to-end path. The forwarding of messages takes place via any nodes that are encountered, and therefore the measurement of message passing efficiency between nodes becomes challenging if a number of different protocols are to be compared and evaluated. Prior work has identified an evaluation framework that addresses this challenge. This article describes the construction of a simulation tool to assist the assessment of efficiency in opportunistic networks, and by way of an exemplar case study, a set of experimental results are discussed and evaluated. From this we conclude that Spray and Focus may be the way forward in this case.
