Conference Proceeding: A new reliable transport scheme in Delay Tolerant Networks based on acknowledgments and random linear coding[show abstract] [hide abstract]
ABSTRACT: We propose a new reliable transport scheme for Delay Tolerant Networks (DTNs) based on the use of acknowledgments (ACKs) as well as coding. We, specifically, develop a fluid-limit model to derive expressions for the delay performance of the proposed reliable transport scheme and derive the optimal setting of the parameters which minimize the file transfer time. Our results yield optimal values for the number of outstanding random linear combinations to be sent before time-out as well as the optimal value of the time-out itself, which, in turn, minimize the file transfer time.Teletraffic Congress (ITC), 2011 23rd International; 10/2011
Conference Proceeding: Combined Congestion Control and Link Selection Strategies for Delay Tolerant Interplanetary Networks[show abstract] [hide abstract]
ABSTRACT: In view of the dense and complex space network topologies envisioned for the future, the management of congestion control is a prominent issue that deserves a particular attention. Given the challenging peculiarities of interplanetary environments, this paper focuses on the advantages offered by storage-based routing and on potentials of implementing Random Early Detection (RED) and Explicit Congestion Notification (ECN) mechanisms within the Delay Tolerant Network (DTN) architecture. In this light, solutions relying upon the aforementioned concepts have been designed and tested. Preliminary results show that combination of RED and ECN schemes with network-selection strategies for storage-based routing is really promising and outperforms other solutions in terms of reliability, network resource utilisation and power consumption.Global Telecommunications Conference, 2009.

Conference Proceeding: Adaptive Erasure Coding Schemes for Interplanetary Networks with Incomplete Channel Side Information[show abstract] [hide abstract]
ABSTRACT: Providing effective telecommunication services over interplanetary networks poses a number of open challenges because of severe impairments exhibited in such environment. In this perspective, this work proposes a coding framework, integrated within the delay tolerant network (DTN) architecture, implementing adaptive erasure coding schemes that rely upon partial observation of the transmission channel dynamics. Three main protocol solutions based upon partial observable Markov decision process (POMDP) and incremental redundancy adaptation (IRA) have been devised and analysed under different scenario configurations. The performance analysis showed promising results and the superiority of the proposed solutions with respect to approaches based upon fixed- rate coding strategies.Global Telecommunications Conference, 2008.
