“…This creates a multihop dynamic wireless network quickly via self-organization [1]. In recent years, ad hoc networks have been widely used in disaster rescue, vehicular networks, battlefields, remote mountain areas, fire zones, earthquake scenarios, multihop satellite networks, and underwater acoustic sensor networks [2]. Owing to the dynamic changes of network topology caused by the high-speed movement of nodes, the exhaustion of battery energy, and the multihop characteristics of ad hoc networks, routing links are broken easily.…”

For the problem of poor link reliability caused by high-speed dynamic changes and congestion owing to low network bandwidth in ad hoc networks, an ant colony routing algorithm, based on reliable path under dual-channel condition (DSAR), is proposed. First, dual-channel communication mode is used to improve network bandwidth, and a hierarchical network model is proposed to optimize the dual-layer network. Thus, we reduce network congestion and communication delay. Second, a comprehensive reliable path selection strategy is designed, and the reliable path is selected ahead of time to reduce the probability of routing restart. Finally, the ant colony algorithm is used to improve the adaptability of the routing algorithm to changes of network topology. Simulation results show that DSAR improves the reliability of routing, packet delivery, and throughput.

“…Alternatively, TFOR considers both the directional and the undirectional flow of traffic density. If Improved Greedy Traffic Aware Routing (E-GyTAR) [22], Traffic Flow-Oriented Routing (TFOR) [23], Intersection-based Connectivity Aware Routing (iCAR) [24], Adaptive Routing Protocol based on QoS and vehicular Density (ARP-QD) [25], and Adaptive QoS based Routing for VANETs (AQRV) [26] are based on the same idea of dynamic junction selection as GyTAR. E-GyTAR and TFOR further consider the flow directions of the roads.…”

A Comprehensive Real-Time Traffic Map for Geographic Routing in VANETs

2017

Vehicular Ad Hoc Networks (VANETs) have attracted a lot of attention during the last decade. VANETs can not only improve driving safety, but also convenience, and support most future Intelligent Transportation System (ITS). Due to the highly dynamic network topology of VANETs, many geographic routing protocols have been proposed and use real-time traffic information as an important metric to select a reliable forwarding path. However, most of the existing works do not describe how to gather real-time traffic. They either assume this information is already available, or can query an existing traffic center. Few studies have noticed this issue but the proposed solutions only consider a small region. In this paper, we propose a Comprehensive Real-Time Traffic Map (CRT Map) to collect wide-ranging real-time traffic information with low overhead. In the design of a CRT Map, the concept of Crowdsensing is adopted. Vehicles cooperatively gather traffic information and share it with each other to construct an overview of the whole road network traffic. In addition, we design a CRT Map Based Routing (CBR), which takes into account the connectivity of consecutive roads in routing decisions. Simulation results show that the CBR can achieve a lower end-to-end delay and a higher packet delivery ratio.

“…This is because the wireless link's health (capacity, stability, path loss, etc.) highly relies on the distance between mobile nodes, and the transmission range of mobile nodes in a MANET is relatively limited compared to networks with centralized fixed infrastructures [13]. Particularly, disconnection between MANET nodes could occur with high likelihood in challenging locations, such as mountaintops and building roofs, due to their long distance from other mobile nodes.…”

In this paper, we propose a cross-domain optimization (CDO) scheme, which optimizes the MANET topology and enables communication between multiple MANETs via LTE. Particularly, we first deploy a gateway to the center of gravity of all nodes in each MANET so that the network topology is optimized. Thus, the aggregation cost of intra-MANET traffic in the gateway is improved. Likewise, we then deploy an eNodeB in the center of gravity of all gateways to establish communication connections between multiple MANETs via LTE. Then, the aggregation cost of inter-MANET traffic at eNodeBs can be largely reduced because of the minimization of the distances between eNodeBs and gateways, along with a significant performance improvement of inter-MANET communications owing to the superiority of LTE. Vis extensive simulations, we validate the effectiveness of our proposed scheme. Our experimental results demonstrate that the CDO scheme can greatly improve network performance. Finally, we discuss some other issues.
