We present a method for accurate aggregation of highway traffic information in vehicular ad hoc networks (VANETs). Highway congestion notification applications need to disseminate information about traffic conditions to distant vehicles. In dense traffic, aggregation is needed to allow a single frame to carry information about a large number of vehicles. Our technique, CASCADE (Clusterbased Acc...

Mobile Ad-hoc Network (MANET) is an autonomous, multi-hop and dynamic network composed of number of wireless mobile nodes. Routing protocols are challenges in designing Mobile Ad-hoc networks with low energy consuming and low control overhead. Ad-hoc on demand distance vector routing protocol (AODV) is specially designed for mobile ad-hoc networks with Expanding Ring Search (ERS) technique for ...

Vehicular Ad hoc Network (VANET) is one of the subset Mobile (MANET) and it a self-organised system with group vehicles, which are capable short-range communication using On Board Unit (OBU). This unit comprised vehicles that possible to communicate nearby vehicles. VANETs rely on heavy broadcast transmission due sharing data (messages) between about traffic, collision so on. redundant informat...

Mobile Ad Hoc Networks provides important control and route establishment functionality for a number of unicast and multicast protocols. To discover an effective and an efficient routing protocol for transmit information from source to destination across whole network topology. This is a main issue in networking research. Broadcasting is important in MANET for routing information discovery, pro...

Using multicast for serving popular movies on demand reduces load on the server and the network by eliminating redundant packet transmission. To permit clients to arrive at times of their choosing, periodic rebroadcast is necessary. In addition, splitting the transmission over multiple multicast groups reduces the cost of rebroadcasting by allowing clients to unsubscribe from groups in which th...

In Mobile Ad Hoc Networks (MANETs), broadcasting is widely used to support many applications. Several adaptive broadcast schemes have been proposed to reduce the number of rebroadcasting, and can consequently reduce the chance of contention and collision among neighboring nodes. In practice, broadcasting is power intensive especially in dense networks. Thus, a good energy-efficient relay scheme...

In mobile ad hoc networks, it is often necessary to broadcast control information to all the constituent nodes in the network. Possible applications include searching for a destination node (as a part of routing) or a particular service such as DNS look-up. Flooding, which is often deployed to achieve the above objective, is expensive in terms of overhead and wastes valuable resources such as b...

Broadcasting is a fundamental operation in MANETs where a source node transmits a message that is to be disseminated to all the nodes in the network. Broadcasting is categorized into deterministic and probabilistic schemes. This paper reviews the probabilistic broadcasting protocol because of its adaptability in changing environment. Probabilistic broadcasting is best suited in terms of ad hoc ...

A wireless sensor network is an ad hoc network consisting of numerous sensor devices (nodes). These nodes are linked via short-range ad hoc radio connections. Each node in such a network has a limited energy resource (battery), and each node operates unattended. Consequently, energy efficiency is an important design consideration for these networks. Inspired by the fact that in complex systems ...

Social media now plays a pivotal role in electoral campaigns. Rapid dissemination of information through platforms such as Twitter has enabled politicians to broadcast their message to a wide audience. In this paper, we investigated the sentiment of tweets by the two main presidential candidates, Hillary Clinton and Donald Trump, along with almost 2.9 million tweets by Twitter users during the ...
