Abstract

Delay-tolerant networks, consisting of a number of intermittently connected wireless devices, are emerging as a promising application field, able to complement in some situations infrastructure-based service delivery. In this work, we propose a marked point process model for characterizing the pattern of contacts among nodes in such systems. The model can be used for deriving analytical results on various performance indexes. Validation of the model is performed through comparison with experimental traces obtained from real-world DTN deployments.
