The Internet of Things is evolving around a plethora of vertical platforms, each specifically suited to a given scenario and often adopting proprietary communications, device and resource control protocols. The emerging need for crossdomain IoT applications and services highlights the necessity of interoperability across IoT platforms for a unified and secure sharing of and access to sensing/actuating resources. This position paper describes the current state of the IoT landscape, the opportunities that appear towards its sustainable evolution as well as the challenges that need to be addressed. In this context, the vision and objectives of the H2020 symbIoTe project are also presented; symbIoTe aims at the interoperability of IoT platforms by offering a flexible interoperability framework that will allow i) vertical IoT platforms to cooperate, ii) collaborative IoT platforms to form IoT-platform federations for exchange of resources and iii) independent developers to create innovative and cross-domain applications.

This paper proposes Adaptive Multi-Path routing (AMP) as a simple algorithm for dynamic traffic engineering within autonomous systems. In contrast to related multipath routing proposals, AMP does not employ a global perspective of the network in each node. It restricts available information to a local scope, which opens the potential of reducing signaling overhead and memory consumption in routers. Having implemented AMP in ns-2, the algorithm is compared to standard routing strategies for a realistic simulation scenario. The results demonstrate the stability of AMP as well as the significant performance gains achieved.

We present the TOTEM open source Traffic Engineering (TE) toolbox and a set of TE methods that we have designed and/or integrated. These methods cover intra-domain and inter-domain TE, IP-based and MPLS-based TE. They are suitable for network optimisation, better routing of traffic for providing QoS, load balancing, protection and restoration in case of failure, etc. The toolbox is designed to be deployed as an on-line tool in an operational network, or used off-line as an optimisation tool or as a traffic engineering simulator. q

The efficient management of natural and man-made disasters typically represents a major information exchange and coordination challenge, as in most countries a number of organizations are involved in all phases of the disaster management cycle. In this article, the authors introduce the approach of the Austrian national project INKA, which aims at improving civil-military interoperability between the Austrian Armed Forces and the corresponding federal state level institutions through the introduction of IT-supported information exchange without media discontinuities. Apart from providing a comprehensive overview of their interdisciplinary research methodology, the authors present a number of important results which are based on a detailed qualitative assessment of stakeholder requirements. Furthermore, they provide first insights into designing a valuable IT-platform for civil-military interoperability in Austria.
