Wireless sensor networks (WSNs) have several important applications, both in research and domestic use. Generally, their main role is to collect and transmit data from an ROI (region of interest) to a base station for processing and analysis. Therefore, it is vital to ensure maximum coverage of the chosen area and communication between the nodes fo...

Satellite image time series (SITS) is a sequence of satellite images that record a given area at several consecutive times. The aim of such sequences is to use not only spatial information but also the temporal dimension of the data, which is used for multiple real-world applications, such as classification, segmentation, anomaly detection, and pre...
Chapter
Solution encoding describes the way decision variables are represented. In the case of permutation problems, the classical encoding should ensure that there are no duplicates. During crossover operations, repairs may be carried out to correct or avoid repetitions. The use of indirect encoding aims to define bijections between the classical permutat...

Abstract The way nodes are arranged in a wireless network can significantly influence performance, especially information flow. The construction of disjoint virtual backbone networks (DVBNs) is one of the ways this can be accomplished. In this study, the authors first present a proposal that constructs multiple DVBNs using nodes' locations, in two...

In this paper, we present two deterministic leader election algorithms for programmable matter on the face-centered cubic grid. The face-centered cubic grid is a 3-dimensional 12-regular infinite grid that represents an optimal way to pack spheres (i.e., spherical particles or modules in the context of the programmable matter) in the 3-dimensional...

Multi-objective genetic algorithms allow solving complex problems. They are often used to solve real-world problems. However, close scrutinizes of the execution of these algorithms show that they could suffer from premature convergence or diversity loss problems. This has an impact on the performance results. This paper introduces some tools for ge...

While wireless sensor networks continue to break new grounds in applications, favored by technological innovations, energy efficiency continues to stagnate. Duty cycling remains the most popular and effective technique used to improve energy efficiency and thus lifetime of the network. Nevertheless, duty cycling imposes temporary unavailability on...

The sensor deployment problem consists in finding an optimal (or near-optimal) way of placing sensors in a given area in order to cover the whole space. However, sometimes it is not necessary to monitor the complete area; one may want to focus on some points considered as target. This leads to the target deployment problem. This problem includes tw...

Le problème de déploiement de capteurs consiste à trouver une stratégie optimale (ou quasi op-timale) pour placer les capteurs dans une zone donnée afin de la couvrir complètement. Cependant, il n'est souvent pas nécessaire de surveiller la totalité de la zone. On peut vouloir se focaliser sur certains points de la zone considérés comme des cibles....

Nowadays, with the miniaturization of communication devices, dense and highly mobile ad-hoc networks are very common. Besides, more and more devices have several radio interfaces. In such an environment, multi-path routing should be considered. Yet, only few multi-path ad-hoc routing protocols take into account the radio-interferences which might a...

Broadcasting efficiently in a Vehicular Ad hoc Network (VANET) is a hard task to achieve. An efficient communication algorithm must take into account several aspects such as the neighboring density, the size and shape of the network, the use of the channel, the priority level of the message. Some studies [6, 12, 13] have proposed new solutions of b...
