Performance Evaluation of Data Disseminations for Vehicular Ad Hoc Networks in Highway Scenarios
Data Dissemination Network Simulation Performance Evaluation Routing Protocols
2015/11/23
A vehicular ad hoc network (VANET) is a relatively new term for an old technology – a network that does not rely on pre-existing infrastructure. When integrated into the intelligent transportation sys...
Resource allocation for QoS provisioning in wireless ad hoc networks
Reflection wireless network transmission data rate the network resources
2015/8/11
For wireless ad hoc networks with multihop transmissions and Rayleigh fading, this paper maximizes the overall system throughput subject to QoS constraints on power, probability of outage, and data ra...
QoS and fairness constrained convex optimization of resource allocation for wireless cellular and ad hoc networks
Wireless cellular network distribution network resources optimization
2015/8/11
For wireless cellular and ad hoc networks with QoS constraints, we propose a suite of problem formulations that allocate network resources to optimize SIR, maximize throughput, and minimize delay. The...
Optimal routes and flows in congestion constrained ad hoc networks
Network streaming media video voice data Internet function
2015/8/11
Future ad hoc and multi-hop networks will simultaneously support many different types of traffic such as streaming video, voice, and data. This is particularly true for emerging 802.11, bluetooth, or ...

Car, network, transport system, mobile Ad Hoc networks
2014/11/7
Vehicular Ad Hoc Networks (VANETs) have been proposed to enhance the safety and efficiency of transportation systems. Such networks hold unique characteristics and fulfill new goals that necessitate t...
Distributed Multiple-Message Broadcast in Wireless Ad-Hoc Networks under the SINR Model
Message Broadcast Wireless Ad-Hoc Networks SINR Model
2012/12/4
In a multiple-message broadcast, an arbitrary number of messages originate at arbitrary nodes in the network at arbitrary times. The problem is to disseminate all these messages to the whole network. ...
