Multiple Access Protocols with Smart Antennas in Multihop Ad Hoc Rural-Area Networks
Multihop ad hoc networking is a very appealing technology for the deployment of wireless data networks. It eliminates the need for network planning and the reliance on fixed infrastructure. Multihop ad hoc networks are designed with a self-configuring capability and are able to adapt to the addition or removal of network radio units (nodes). This capability makes them simple to install, allowin...
متن کاملAsympotic capacity bounds for ad-hoc networks revisited: the directional and smart antenna cases
Directional and smart antennas can be useful in increasing the capacity of wireless ad hoc networks. A number of media access and routing protocols have been recently proposed for use with such antennas, and have shown significant performance improvements over the omni-directional case. However, it is important to explore if and how different directional and smart antenna designs affect the asy...
متن کاملEvaluation of a BIBD Based Directional MAC Protocol for Wireless Ad Hoc Networks
The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...
متن کاملاستفاده از خوشه بندی در پروتکل مسیریابی AODV برای شبکه های بین خودرویی بر روی سناریوی بزرگراه
Vehicular Ad hoc networks are a subset of mobile Ad hoc networks in which vehicles are considered as network nodes. Their major difference is rapid mobility of nodes which causes the quick change of topology in this network. Quick changes in the topology of the network are considered as a big challenge For routing in these networks, routing protocols must be robust and reliable. AODV Routing pr...
متن کاملMAC Protocol for Ad Hoc Networks Using Smart Antennas for Mitigating Hidden and Deafness Problems
We herein propose a MAC protocol for the smart antenna network, which applies pulse/tone exchange prior to the RTS/CTS handshake process. RTS frame collisions are drastically reduced with little additional overhead due to pulse/tone exchange in the proposed protocol. In addition, the number of exposed nodes is reduced by using smart antennas. Furthermore, since the occurrence of the deafness pr...
