There are a number of proposals to achieve energy-efficient broadcasting in wireless multihop networks using directional antennas. However, these proposals are based on centralized algorithms, which require global knowledge of the topology of the network. Such global protocols are not suitable for ad hoc networks because of the high number of control(More)
Ad hoc nodes are usually battery-powered. Thus, energy-efficiency is of paramount importance in wireless ad hoc and sensor networks. The use of directional antennae helps to reduce energy consumption by aiming the beam only to the intended target using less energy. In addition, this kind of networks have limited resources in terms of bandwidth. Thus, the(More)
This study tests the direct relevance of justifications and social comparisons (predictors of perceptions of fairness) on different types of household labour distribution, and the importance of masculinity ideology and neosexism on these variables. The participants were heterosexual dual-earner couples. Our results showed that both men and women use more(More)
Most of the previous efforts regarding multicast routing in MANETs, have been devoted to the provision of low-control overhead protocols, being able to maximize the packet delivery ratio. In multicast routing, the non-optimality of the forwarding structure can also lead to transmission of additional data packets (compared to the minimum required). We call(More)
