This paper evaluates the performance of the routing protocols HWMP, Babel and B.A.T.M.A.N. advanced for disaster networks. The evaluation is performed using a virtual environment so that the obtained results are similar to the expectations of a real world testbed. According to the specific requirements in disaster situations, three different scenario categories are implemented. The focus of the scenarios...
The advances in the telecommunication domain to support complex communication services has resulted in a need for a new approach to automatically verify that the communication services meet the demands of the customers. This paper presents a concept for automated functional testing by means of a novel test framework. Within the framework, the tests are automatically derived from a proposed new sort...
This publication presents a novel concept to provide and use services in a Peer-to-Peer (P2P) connected Machine-To-Machine (M2M) community. Service compositions are presented that address several application fields like Ambient Assisted Living, traffic, energy, electro mobility, logistic or surveil-lance. The successfully implemented concept for optimisation of energy management in the local grid...
The increasing demand for value added services is a driver for telecommunication companies to find simple and cost efficient solutions for automated service creation, as bespoke service development for small customer groups is not economically viable. The aim of this paper is to propose a peer-to-peer based environment that supports deployment and discovery of value-added services. The identified...
This paper presents a new passive technique for estimating the bottleneck bandwidth based on transferring the Gaussian kernel density estimation of the packets inter-arrival times to the frequency domain. The resulting spectrum contains information about the transmission time of the bottleneck link and can reveal information about multiple bottlenecks if they exist along the end-to-end path. The advantage...
TCP remains the protocol of choice for bulk data transfers over the Internet. A range of mathematical approaches were proposed to evaluate the performance of TCP, approaches validated through synthetic or endpoint controlled traffic, typically unsuitable for short-lived transfers or clients with unknown behaviour. This paper aims to overcome these problems by using a supervised adaptive learning approach...
