Abstract
On-line end-to-end Service Level Agreement (SLA) monitoring is of key importance nowadays. For this purpose, recent researches have focused on measuring (when possible), or estimating (most of the times) network Quality of Service (QoS) and performance parameters. Up to now, all the proposed solutions have the drawback of requiring a huge amount of resources with low accuracy, generally leading to unscalable systems. We observe, however, that the accurate estimation of network QoS parameters is not necessarily required for SLA assessment. What is required is an efficient and scalable method to directly detect SLA violations. To this end, this paper makes the following contributions. First, we introduce a polynomial-complexity algorithm based on Hausdorff Distance that efficiently detects SLA violations. Second, we propose a Simplified Hausdorff Distance, which provides better accuracy at lower computational cost. Our solution works on simple to measure time seriesthe Inter-Packet Arrival Times (IPATs) received in our case. The validity of our proposal is confirmed by comparing with perfect knowledge of the QoS status as well as other existing alternatives in a real testbed.

Abstract
The behavior of Wireless Sensor Networks (WSN) is nowadays widely analyzed. One of the most important issues is related to their energy consumption, as this has a major impact on the network lifetime. Another important application requirement is to ensure data sensing synchronization, which leads to additional energy consumption as a high number of messages is sent and received at each node. Our proposal consists in implementing a combined synchronization protocol based on the IEEE 1588 standard that was designed for wired networks and the PBS (Pairwise Broadcast Synchronization) protocol that was designed for sensor networks, as none of them is able to provide the needed synchronization accuracy for our application on its own. The main goals of our new synchronization protocol are: to ensure the accuracy of local clocks up to a tenth of a microsecond and to provide an important energy saving. Our results obtained using NS-2 (Network Simulator) show that the performance of our solution (IEEE 1588-PBS) matches our application requirements with regard to the synchronization, with a significant improvement in energy saving.
