Power management is an important issue in wireless sensor networks (WSNs) because
wireless sensor nodes are usually battery powered, and an efficient use of the available …

It is well known that IEEE 802.11 WLAN is highly inefficient for transporting voice data. For
example, if one simply takes the data rate of 802.11 b, 11 Mbps, and divide it by two times …

In this paper, we propose Opportunistic Carrier Prediction (OCP) that jointly addresses
exposed terminal and hidden terminal problems in wireless networks. OCP is based on the …

Unlike traditional wireless networks, characterized by the presence of last-mile, static and
reliable infrastructures, Mobile ad Hoc Networks (MANETs) are dynamically formed by …

Wireless networks are becoming ubiquitous. They have numerous applications also outside
the cellular systems, for example in agriculture, multi-user games, health monitoring using …

In wireless ad hoc network, hidden and exposed node problem can cause the throughput
performance degradations. Hidden Node (HN) allows to transmit but interferes with the …

Wireless networks have raised great attention in the past decades because they provide
tether-free connectivity. Although much of the effort in wireless network research has been …

Sensor network's MAC protocols differ greatly from traditional wireless network's MAC
protocols in many issues. MAC protocols for WSNs must have built-in power conservation …

Wireless mesh networks (WMNs) are an alternative technology for last-mile broadband
Internet access that can support broadband services. However, for a WMN to be all it can be …

El trabajo fin de grado ha consistido en la implementación en el software de código libre
Network Simulator 3 y su posterior evaluación de diferentes soluciones y estrategias de …
