The Information and Communication Technologies have been increasingly playing an essential role to support teaching and learning, especially in engineering courses, by taking advantage of online resources and online experiments. In particular, Wireless Se... see more

Most existing algorithms used for constructing virtual backbones are based on the ideal deterministic network model (DNM) in which any pair of nodes is either fully connected or completely disconnected. Different from DNM, the probabilistic network model ... see more

Wireless sensor networks have become an increasingly important area for research and application. Compared to traditional networks, its security faces many unfavorable factors such as severe resource constraints, inability to secure the wireless medium, p... see more

Gathering data in an energy efficient manner in wireless sensor networks is an important design challenge. In wireless sensor networks, the readings of sensors always exhibit intra-temporal and inter-spatial correlations. Therefore, in th... see more

Wireless sensor networks produce a large amount of data that needs to be processed, delivered, and assessed according to the application objectives. Cluster-based is an effective architecture for data-gathering in wireless sensor networks. Clustering prov... see more

This paper examines the issue of energy utilization in wireless sensor networks. Wireless sensor nodes sent in brutal condition where the conditions change radically experience the ill effects of unexpected changes in connect quality and node status. The ... see more

Location information is prerequisite for wireless sensor networks (WSNs) monitoring and control applications, since there is no meaning without position information for collected data. Distance vector hop (DV-Hop) localization algorithm as the typical ran... see more

Wireless Sensor Networks (WSNs) are receiving an ever increasing attention because they are one of the most important technologies enabling the Internet of Things vision. Since nodes of these networks are battery-powered, energy efficiency represents one ... see more

This paper focuses in the selection of an optimal path pair for cooperative diversity based on cross-layer optimization in multihop wireless ad hoc networks. Cross-layer performance indicators, including power consumption, signal-to-noise ratio, and load ... see more
