Directional MAC Protocols in Ad-Hoc Networks
In wireless ad-hoc networks, the beam forming antenna technology is a new and promising solution to many challenges. Beam forming antennas have the ability to increase the spatial reuse, improve the transmission reliability, extend the transmission range and/or save the power consumption. If they are effectively used, they can significantly improve the network capacity, lifetime, connectivity a...
متن کاملRouting Protocols in Mobile Ad-hoc Networks
A Mobile Ad Hoc Networks (MANETs) is a group of mobile nodes which cooperate in forwarding packets in a multi-hop fashion without any centralized administration. One of its key challenges is routing. Many routing protocols for MANET have been proposed and the protocols can be classified as proactive routing and on demand routing protocols. This paper uses ns-2 as the simulation tool, 802.11 as ...
متن کاملDesign and evaluation of two scalable protocols for location management of mobile nodes in location based routing protocols in mobile Ad Hoc Networks
Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

متن کاملRouting protocols for mobile ad hoc networks
Mobile ad hoc networks are short live networks establish by mobile nodes without the intervention of any centralized structure. Absence of any fixed infrastructure pose number of different problems to this area. Some of the challenges which require standard solutions include routing, bandwidth constraints, hidden terminal problem and limited battery power. Routing is the process of information ...
