	abstract = {In this paper, we are interested in the description of a cross-layer architecture that supports service differentiation for real-time and best-effort traffics in Wireless Sensor Networks (WSN). We present our mathematical model that combines parameters from network and MAC layers. We aim to estimate and to enhance the throughput of multi-hop WSNs and the stability of the forwarding queues used for real-time and besteffort traffics. We suppose at the first step that we have a wireless sensor network with a single sink then we suppose that we have the same wireless sensor network with two sinks. We study the impact of transmitting real-time and best-effort traffics on the system throughput; and we also study the impact of adding a second sink on the throughput. {\textcopyright} 2014 IEEE.},

	abstract = {In this paper, we are interested in the service differentiation for real-time and besteffort traffics in wireless sensor networks. We present a new model that takes into account a random access in the MAC layer and a forwarding probability formulation at the network layer. We propose an approach (based on transmissions cycle) to derive the throughput of multi-hop routes and to estimate the stability of forwarding queues for real-time and best-effort traffics. We study the impact of some metric parameters: density, hop count, time, velocity and Mobility Models on the quality of service (QoS) of the studied system. In this paper, we have studied the impact these parameters on the QoS of a Wireless Sensor Network (WSN) where all nodes have a single destination (sink node). As results, we notice that the transmission probability Pi of the realtime and best-effort traffics have a great impact on the average throughput and we have also shown the correlation between the throughput and all metrics studied except for the hop count metric of best-effort streams. {\textcopyright} 2013 Praise Worthy Prize S.r.l. - All rights reserved.},

	abstract = {The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of the implemented routing protocol to adapt itself to unpredictable changes of topology network and link status. The Optimized Link State Routing (OLSR) protocol is a one key of the proactive routing protocols for MANETs. It is based on the multi-point relays (MPRs) technique to reach all nodes in the network with a limited number of broadcasts. In this paper, we propose new version of the original OLSR protocol based on a new density parameter, in the goal to enhance and adapt it in the presence of the mobility. Also we will analyze and compare the performance of protocols based on a density criterion (Di1OLSR \& D2iOLSR), mobility criterion (MobOLSR) and OLSR standard using NS-2 network simulator.},

	abstract = {The main ad hoc routing protocols that were proposed generally operate only on flat networks. However the IP networks have always been of a hierarchical nature, for scalability and manageability reasons. In this paper, we propose a novel clustering algorithm for OLSR based on the density and mobility of nodes. Our algorithm takes into account the node mobility and gives major improvements regarding the number of elected cluster heads. Our objective is to elect a reduced and less mobile cluster heads that will serve for provide hierarchical routing using OLSR.},
