Karabulut, Muhammet Ali; Shah, A. F. M. Shahen; İlhan, Hacı (Oğuzhan Yılmaz, 2020)IEEE 802.11 standardı, araçsal tasarsız ağlar (Vehicular Ad Hoc Networks, VANETs) için ortam erişim kontrolü (Medium Access Control, MAC) ve fiziksel (PHY) katmanının özelliklerini tanımlamaktadır. IEEE 802.11 standardında, ... -
OEC-MAC: A Novel OFDMA Based Efficient Cooperative MAC Protocol for VANETS
Karabulut, Muhammet Ali; Shah, A. F. M. Shahen; İlhan, Hacı (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA, 2020)In vehicular ad hoc networks (VANETs), mobility between vehicles can cause rapid topology changes with frequent disconnections, which result in collisions and packet losses that make communications unstable. Alternatively, ... -
Performance modeling and analysis of the IEEE 802.11 MAC protocol for VANETs
Karabulut, Muhammet Ali; Shah, A. F. M. Shahen; İlhan, Hacı (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, BAYAR BULVARI, MALTEPE, ANKARA, 06570, TURKEY, 2020)The IEEE 802.11 standard defines the specifications of the media access control (MAC) and physical (PHY) layers for vehicular ad hoc networks (VANETs). In IEEE 802.11, distributed coordination function (DCF) is the fundamental ... -
Performance Optimization of Cluster-Based MAC Protocol for VANETs
Shah, A. F. M. Shahen; Karabulut, Muhammet Ali; İlhan, Hacı; Türeli, Ufuk (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141, 2020)Recently, a novel cluster-based medium access control (CB-MAC) protocol has been proposed for vehicular ad hoc networks (VANETs). Though performance of CB-MAC protocol is affected by cluster size, no mechanism is provided ... -
Survey and Performance Evaluation of Multiple Access Schemes for Next-Generation Wireless Communication Systems
Shah, A. F. M. Shahen; Qasim, Ahmed Nidham; Karabulut, Muhammet Ali; İlhan, Hacı; Islam, Md. Baharul (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141, 2021)Mobile communication systems are always in continuous evolution due to the demands of the end-users using this technology. Therefore, before the possible launch of 5G, some technologies have opened the way to the new ...
