A Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
متن کاملAn efficient and fair reliable multicast protocol for 802.11-based wireless LANs
Many applications are inherently multicast in nature. Such applications can benefit tremendously from reliable multicast support at the MAC layer since addressing reliability at the MAC level is much less expensive than handling errors at the upper layers. However, the IEEE 802.11 MAC layer does not support reliable multicast. This void in the MAC layer is a limiting factor in the efficacy of m...
متن کاملStudy of IEEE 802.11 Modified MAC
In some recent researches Distributed Coordinate Function becomes an important mechanism in order to access the medium (Channel). The IEEE 802.11 protocol is based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) with a binary exponential backoff (BEB) algorithm to access the channel as the architecture of 802.11 handles MAC(Medium Access Control) layer and specification of P...
متن کاملSRN Model for IEEE 802.11 DCF MAC Protocol in Multi-hop Ad Hoc Networks with Hidden Nodes
Since its development for WLAN, IEEE 802.11 standard has been widely used for various wireless networks due to the low cost and effectiveness in reducing collisions with simple and decentralized mechanisms. In this paper we present a novel analytical SRN model for performance evaluation of IEEE 802.11 DC F MAC protocol in multi-hop ad hoc networks in the presence of hidden nodes, taking into ac...
متن کاملAdapting MAC 802.11 Adapting MAC 802.11 for Performance Optimization of MANET using Cross Layer Interaction
In this research, we study the optimization challenges of MANET and cross-layer technique to improve its performance. We propose an adaptive retransmission limits algorithm for IEEE 802.11 MAC to reduce the false link failures and predict the node mobility. We implemented cross layer interaction between physical and MAC layers. The MAC layer utilizes the physical layer information for different...
