We show that there is a trade-off among mobility, capacity, and delay in ad hoc networks.
More specifically, we consider two schemes for node mobility in ad hoc networks. We divide …

Wireless networks are characterized by a dynamic topology triggered by the nodes mobility.
Thus, the wireless multi-hops connection and the channel do not have a determinist …

In this paper we propose a novel three phase route recovery mechanism for routing over
switched single beam directional antennas. We enhance the popular dynamic source …

(in English) Directional antenna is one of the most promising ways of improving spatial
usage of wireless channel in ad hoc networks. In ad hoc networks, it will be general situation …

Mobile ad hoc networks suffer from the re-construction of the routing path as a node on the
path moves away and/or fails. In this paper we propose a multipath routing scheme …

Many real systems are hybrid networks which include infrastructure nodes in multi-hop
wireless networks, such as sinks in sensor networks and mesh routers in mesh networks …

The use of smart antennas in wireless ad hoc networks has garnered attention over the last
few years. Given the unique capabilities of smart antennas, and how they can improve …

In this paper, we investigate the effect of Rayleigh fading on the connectivity of wireless ad
hoc networks. We consider static nodes that are equipped with omnidirectional antennas …
