Security in Mobile Ad hoc NETworks (MANETs) is a very prolific research topic. Many solutions have already been proposed to solve important security flaws regarding routing protocols conceived for these emerging networks. However most of them just focus on a small part of the security problems and only few frameworks have been proposed yet. In this paper we(More)
Quality of service (QoS) is a key problem in wireless environments where bandwidth is scarce and channel conditions are time varying and sometimes implies highly packet losses. IEEE 802.11b/g/a wireless LAN (WLAN) are the most widely used WLAN standards today, and the IEEE 802.11e QoS enhancement standard exists and introduces QoS support for multimedia(More)
Wireless sensor nodes can organize themselves after deployment in a large scale ad hoc network topology. Some traditional Ad hoc routing protocols do not take into account that a sensor node has limited capacities, e.g. energy. Therefore, they try to perform the sensing task regardless of the maximum hops and duration it takes. In wireless sensor networks(More)
