In this paper, we propose, a multi-attributes and adaptive approach for Context Level Agreements (CLAs) negotiation between a context provider and a context consumer using a context broker. The approach employs a Nash bargaining model and evaluates the global utility of each party as a linear function of normalized Quality of Context (QoC) attributes during the rounds of negotiation. The ultimate goal is to improve context-based adaptation of context-aware applications and services. One of the advantages of this approach is that it permits to resolve conflicts of interests between the context provider and the context consumer when the global utility of each party reaches a Pareto optimum.}, isbn = {978-981-287-990-5; 978-981-287-989-9}, issn = {1876-1100}, doi = {10.1007/978-981-287-990-5\_8}, author = {Routaib, Hayat and Badidi, Elarbi and Sabir, Essaid and Elkoutbi, Mohammed}, editor = {Sabir, E and Medromi, H and Sadik, M} } @conference { ISI:000381755100026, title = {An Energy-Aware Clustering Approach Based on the K-Means Method forWireless Sensor Networks}, booktitle = {ADVANCES IN UBIQUITOUS NETWORKING}, series = {Lecture Notes in Electrical Engineering}, volume = {366}, year = {2016}, note = {International Symposium on Ubiquitous Networking (UNet), Casablanca, MOROCCO, SEP 08-10, 2015}, pages = {325-337}, abstract = {This paper describes a new approach to build energy aware clusters for Wireless Sensor Networks (WSN). The algorithm behind is based on the k-means method which is well known as a clustering technique and widely used in several fields of engineering and research. K-means clustering tends to find clusters of comparable spatial extent (density clustering). We try to enhance the clustering process by selecting nodes as clusters that are centric and have a high level of energy. This will give the same QoS results as given by the K-means approach with a reduction of energy consumption and a prolongation of the lifetime of the sensor network. For the simulation purposes, we have implemented our approach on the OLSR routing protocol which has been selected by our research team as a test bed routing protocol. We have compared our new approach (OLSR-Kmeans-Energy) with a previous work we developed and where we use a Max-Min heuristic (OLSR-MaxMin-Energy) to enhance QoS parameters and the lifetime of the WSN. Our new approach seems to give better results than the MaxMin approach.}, isbn = {978-981-287-990-5; 978-981-287-989-9}, issn = {1876-1100}, doi = {10.1007/978-981-287-990-5\_26}, author = {El Mezouary, Ridouane and Choukri, Ali and Kobbane, Abdellatif and El Koutbi, Mohammed}, editor = {Sabir, E and Medromi, H and Sadik, M} } @conference { ISI:000381755100043, title = {Enterprise Architecture Complexity Component Based on Archimate Language}, booktitle = {ADVANCES IN UBIQUITOUS NETWORKING}, series = {Lecture Notes in Electrical Engineering}, volume = {366}, year = {2016}, note = {International Symposium on Ubiquitous Networking (UNet), Casablanca, MOROCCO, SEP 08-10, 2015}, pages = {535-546}, abstract = {Enterprise architecture (EA) is a business and IT management tool that has grown in popularity during the last decade.
