In this paper we consider that nodes in a Delay Tolerant Network (DTN) may collaborate to minimize the sum of local objective functions, depending in general on some parameters or actions of all the nodes in the network. If the local objective functions are convex, it can be adopted a recently proposed computation framework, that relies on local sub-gradient methods and consensus algorithms to average each node information. Existing convergence results for this framework can be applied to DTNs only in the case of nodes' synchronous operation and simple mobility models without memory. We address both these issues. First, we prove convergence to the optimal solution for a more general class of mobility processes. Second, we show that, under a...
