Performance Analysis of MAC Protocol for Reliable Broadcast in VANETs
Wireless communications are becoming the dominant form of transferring information,and the most active research field. In this dissertation, we will present one of the most applicable forms of Ad-Hoc networks; the Vehicular Ad-Hoc Networks (VANETs). VANET is the technology of building a robust Ad-Hoc network between mobile vehicles and each other, besides, between mobile vehicles and roadside u...
متن کاملSynthesizing Existing CSMA and TDMA Based MAC Protocols for VANETs
Many Carrier Sense Multiple Access (CSMA) and Time Division Multiple Access (TDMA) based medium access control (MAC) protocols for vehicular ad hoc networks (VANETs) have been proposed recently. Contrary to the common perception that they are competitors, we argue that the underlying strategies used in these MAC protocols are complementary. Based on this insight, we design CTMAC, a MAC protocol...
متن کاملA MAC Layer Protocol for Priority-based Reliable Broadcast in Wireless Ad Hoc Networks
RTS-CTS handshake based protocols achieve “reliable unicast” by eliminating the hidden node problem effectively, however, these solutions are not directly or efficiently generalizable for solving the single-hop “reliable broadcast” problem, and broadcast remains as a best-effort operation in wireless ad hoc networks. Here we present a simple, light-weight, and self-stabilizing MAC protocol, nam...
متن کاملBayes Timeslot Utilization for Efficient Contention Access in VeMAC-VANET
Vehicular ad hoc networks (VANETs) are high priority safety applications that need medium access control (MAC) protocol for efficient broadcast service. The existing work presented VeMAC, a novel multi channel TDMA MAC protocol for VANET supports efficient one-hop and multi-hop broadcast services on control channel using implicit acknowledgments and eliminating hidden terminal. The drawbacks of...
متن کاملECCT: An Efficient-Cooperative ADHOC MAC for Cluster-Based TDMA System in VANETs
In VANETs, a clustering algorithm can be used to partition the network into smaller segments.Therefore, the clustering algorithms provide not only limited channel contention but also fair channel access within the cluster. In addition, they also increase spatial reuse in VANETs and efficient control for the network topology.Themain concern in the clustering algorithm is the cluster stability. T...
