Modern cities are blanketed with Wi-Fi Hotspots. Such network access points can be utilised by Internet of Thing devices to enable wireless sensor network data mining deployments to report to the cloud. Vehicles are such devices that can provide valuable data sensing platforms for both internal operational properties such as speed, fuel and engine heat as well as external environmental features including...
Vehicular Ad hoc Networks (VANETs) are one of the building blocks for future Intelligent Transportation Systems (ITS). They will support applications for safety and entertainments on the streets. VANETs also provide an excellent potential for on-demand services. Such services in VANETs require real-time request-reply routing between vehicle client and service provider, and also tracking of client...
Being a subclass of mobile ad hoc networks (MANETs), vehicular ad hoc networks (VANETs) have received considerable attention in recent years. Existing routing protocols of MANETs do not perform well for VANETs due to many different characteristics such as, fast moving nodes and frequent disconnections in the network. We present a context-aware hierarchical routing protocol based on road connectivity...
Vehicular ad hoc networks have received considerable attention in recent years. Being a subclass of mobile ad hoc networks, VANETs have some different characteristics than MANETs such as, fast moving nodes and frequent disconnections in the network. Existing routing protocols of MANETs do not perform well under these dynamic conditions in VANETs. We present a two-level hierarchical routing protocol...
Vehicular Ad Hoc Network (VANET) is considered as a special application of Mobile Ad Hoc Networks (MANETs) in road traffic, which can autonomously organize networks without infrastructure. VANETs enable vehicles on the road to communicate with each other and with road infrastructure using wireless capabilities. In the last few years, extensive research has been performed to extend Internet connectivity...
We develop an intelligent distributed quality-of-service (QoS) control scheme which inter-operates between mobile routers, managing vehicular networks mobility, and road communication gateways (RCGs). This scheme manages vehicle-to-infrastructure (V2I) communications by enabling multi-homed vehicular networks to evenly distribute traffic among egress links of their mobile routers based on vehicular...
An ad hoc network is a decentralized network that consists of mobile nodes with wireless communication devices without the aid of access points. A Vehicular Ad-hoc Networks (VANETs) is one of the representative application of ad hoc networks. Epidemic Routing has been proposed as a routing protocol based on Store-Carry-Forward mechanism for VANETs environment. However, in Epidemic Routing, network...
In this paper, we propose a new intersection-based geographical routing protocol, called delay tolerant routing protocol (DTRP) that adapts to the changes in the local topology within city environments. DTRP is based on an effective selection of road intersections through which a packet must pass to reach the gateway to the Internet. The selection, in such delay tolerant VANETs, is made in a way that...
Being composed of car electronics and road-side communication devices, vehicular ad hoc networking (VANET) is the heart of intelligent transportation system. Beside car-to-car communications, the system also communicates to centralized points in infrastructure networks. Given that data load is heavy when the density of cars is high and that they move fast, roadside electronics potentially face congestion...
Wireless mesh network (WMN) has become a popular access network architecture. But because of its multi-hop nature, co-channel interference and contention, the attainable capacity of a wireless node in a WMN is significantly less than the radio capacity. We propose a overlay architecture for a WMN, where a wireless-ring (WRing) is deployed over the regular mesh for carrying wireless mesh traffic only...
