Mobile Ad Hoc Network or MANET is a group of mobile devices, e.g., laptops, mobile phones, radios, or sensors that communicate with each other wirelessly — standard Wi-Fi, cellular, local RF network, etc.—and provides the needed network functionality without an existing fixed structure. They can change locations and reconfigure themselves while doing so. MANETs can be restricted to a local group of wireless devices or they can be connected to the Internet. A VANET (Vehicular Ad Hoc Network) is a MANET that lets vehicles communicate with roadside equipment. Even if the vehicles do not have an Internet connection, the wireless roadside equipment may be connected to the Internet, therefore allowing the vehicles' data to be conveyed over the Internet.

In this paper, we quantitatively investigate the impacts of node selfishness caused by energy depletion in MANETs in terms of packet loss rate, round-trip delay, and throughput. We conducted extensive measurements on a proper simulation platform incorporating an OMNeT++ and INET Framework. Our experimental results quantitatively indicate the impact of node selfishness on the network performance in MANETs. The results also imply that it is important to evaluate the impact of node selfishness by jointly considering selfish nodes’ mobility models, densities, proportions, and combinations.

An Electronic Control Unit (ECU) is an embedded system that controls electrical subsystems in a transport vehicle. Modern motor vehicles have up to 80 ECUs.

Internet of Things (IoT) has seen exponential growth over the past couple of years. A new study from International Data Corporation (IDC) estimates that there will be almost 42 billion connected devices within the year 2025, generating over 80 zettabytes (ZB) of data. As the number of IoT devices grows; the amount of data grows, along with that, grows the need for superior network instruments; which can support this load. However, if we consider a common host (like a generic router), it can connect to a limited number of nodes, less than 32 to be exact. And with an increasing number of IoT devices that could be in our home or industry, this is not sufficient. Currently, there are two solutions to this problem: The first one is to use a Mesh Router that can handle a lot more connections compared to a generic one, or we can use a network protocol known as Mesh Network.

Ad hoc peer-to-peer networks can provide reliable communications in emergency situations where fixed infrastructures, like base stations, may not be available. A mobile ad hoc network (MANET) is a self-configuring network of mobile devices connected without infrastructures or wires. These networks operate independently and can be comprised of one or many transceivers. Remcom’s introduction of transceivers provides a quick way to set up and model ad hoc networks where nodes can act as both a transmitter and receiver. The scenario described here is loosely based on that described in the AT&T article, Scalable Ad Hoc Wireless Geocast.

The mesh is a mass expansive, robust, self-forming and self-healing resilient network created through multi-hop routing.

There is a large and passionate debate going on in our society on the future of the car, mostly revolving around the vehicle drivetrain. However, there is a larger issue that will apply to every vehicle in the future, regardless of the motive force under the hood. That issue is the development of the connected car and its related infrastructure. This connectivity is inevitable. Cars are one of the few areas in society being impacted by every single disruptive technical advance being commercialized today from advanced power electronics to autonomous intelligent systems. Add cloud connectivity required for the vehicle infotainment and navigation systems, and you have the building blocks of a smart traffic environment.
