Session resumption type negotiation enables the client and the server to explicitly agree on the session resumption mechanism for subsequent handshakes, thus avoiding unnecessary overheads occurring with the existing specifications. Session resumption without client-side state additionally enables a constrained DTLS client to resume a session without the need to maintain state while the session is inactive.

Due to channel-dependent scheduling at the base station, these performance models are not simple to obtain. Furthermore, upcoming cellular systems will be interference-limited, hence, the way interference is modeled is crucial for the accuracy. In this paper we present an analytical model for the SINR distribution of the scheduled subcarriers of an OFDMA system with proportional fair scheduling. The model takes the precise SINR distribution into account. We furthermore refine our model with respect to uniform modulation and coding, as applied in LTE networks. The derived models are validated by means of simulations. In additon, we show that our models are approximate estimators for the performance of rate-based proportional fair scheduling, while they outperform some simpler prediction models from related work significantly. https://www.comsys.rwth-aachen.de/fileadmin/papers/2013/2013_VTC_parruca.pdf Proceedings of IEE Vehicular Telecommunications Conference (VTC-Fall 2013) Las Vegas, USA 2013 IEEE 78th Vehicular Technology Conference 2-5, September, 2013 DonaldParruca MariusGrysla SimonGörtzen JamesGross techreport draft-hummen-dtls-extended-session-resumption-00 2013 7 15 draft-hummen-dtls-extended-session-resumption-00 This draft defines two extensions for the existing session resumption mechanisms of TLS that specifically apply to Datagram TLS (DTLS) in constrained network environments.

An application scenario is a Smart City in which the city infrastructure, cars, and people exchange information to enable new services. IP protocols, such as IPv6, TCP and HTTP will be further complemented by IPv6 over Low powerWireless Personal Area Networks and Constrained Application Protocol currently in development in IETF. Security and privacy are a must for the IP-based IoTs in order to ensure its acceptance. However, mobility, limited bandwidth, and resource-constrained devices pose new challenges and require for a sound and efficient security architecture. In particular, dynamic association of mobile smart objects and the management of keys in large-scale networks remain an open challenge. In this context, we propose a flexible security architecture based on the Host Identity Protocol and Multimedia Internet KEYing protocols allowing for secure network association and key management. HIP - based on asymmetric-key cryptography - ensures unambiguous thing identification, mobility support, as well as a lightweight and secure method for network association. In our solution, HIP is extended with MIKEY capabilities to provide enhanced key management using polynomials, which allow to generate pairwise keys with any node based on its identity. This combination of protocols and crypto-algorithms ensures both strong security and very good performance as shown by our implementation and presents clear advantages compared with other alternatives.

Dynamic scheduling brings the advantage of exploiting instantaneous channel state information while it puts on the other hand a significant burden on the system in terms of overhead and computation requirements. Especially for small packets that show up periodically, the overhead is typically too high. Therefore, the base station can serve such packet flows by the semi-persistent scheduling mode. In this mode, a certain resource allocation is fixed to a periodic schedule. While this does not allow any longer to exploit instantaneous channel states, it requires much less overhead. In this paper, we address the problem of selecting a modulation and coding scheme for such semi-persistent scheduling grants. The problem lies here in the stochastic characterization of the resource blocks over the next few seconds while on the other hand estimating based on such a characterization the blok error rate (and hence the average goodput). We provide a novel scheme, which outperforms all previously presented schemes significantly. The underlying model that we provide can also be used for any other long-term decision in an LTE system with semi-persistent scheduling such as interference coordination, handover decision etc. Long Term Evolution;decision making;dynamic scheduling;error statistics;modulation;radio links;resource allocation;stochastic processes;wireless channels;LTE networks;base station;blok error rate;data scheduling;down-link;dynamic scheduling;instantaneous channel state information;long-term decision;modulation selection;packet flows;periodic scheduling;rate selection analysis;resource allocation;resource blocks;semi-persistent scheduling mode;stochastic characterization www.performance.rwth-aachen.de/publications/conferences/2013ICNC_parruca.pdf http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6504261 San Diego, USA International Conference on Computing, Networking and Communications (ICNC) 2013 28-31 January 2013 English 978-1-4673-5287-1 10.1109/ICCNC.2013.6504261 DonaldParruca JamesGross inbook 2013-book-weingaertner-benchmarking-p2p 2013 7847 69-79 http://link.springer.com/chapter/10.1007/978-3-642-38673-2_5 2016-11-11 Print Effelsberg, Wolfgang and Steinmetz, Ralf and Strufe, Thorsten Springer Lecture Notes in Computer Science Content Delivery Overlays EN 978-3-642-38672-5 10.1007/978-3-642-38673-2_5 EliasWeingaertner RenéGlebke AlexanderHocks conference EW2013_parruca_gross 2013 8 In this paper we consider the design of semi-static inter-cell interference coordination schemes for LTE networks. In this approach, base stations coordinate the power settings per resource block over long time spans such as seconds. In order to optimize the power settings, one needs to employ models which predict the rate of terminals over the next coordination period under the usage of a given power setting. However, these models are typically quite simple and neglect the impact from fading as well as from dynamic resource allocation performed at the base stations on a millisecond basis. Ignoring such properties of OFDMA networks leads therefore to suboptimal transmit power settings. In this paper, we study the impact from a precise rate prediction model that accurately accounts for fading and dynamic resource allocation. On the down-side, this more precise model leads to a much more involved optimization problem to be solved once per coordination period. We propose two different heuristic methods to deal with this problem. Especially the usage of genetic algorithm results to be promising to counteract the complexity increase. We then study the overall system performance and find precise rate prediction models to be essential for semi-static interference coordination as they provide significant performance improvements in comparison to approaches with simpler models.
