In the Vehicular ad hoc networks (VANETs), due to the high mobility of vehicles, the network parameters change frequently and the information which the sender maintains may outdate when it wants to transmit data packet to the receiver, so for improving the routing effective, we propose the probability prediction based reliable (PRO) opportunistic routing for VANETs. The PRO routing algorithm c...

Mobile Ad hoc Network is an impromptu wireless network consisting of mobile, self governing independent nodes. Routing in Mobile Ad hoc Networks has been a major concern due to its dynamic topology, lossy and unreliable links. In traditional routing, a single specific node is selected in prior as the potential next-hop forwarder for a packet. Unlike traditional routing, a category of routing te...

The ease of deployment and the auto-configuration capabilities of Wireless Sensor Networks (WSNs) make them very attractive in different domains like environmental, home automation or heath care applications. The use of multichannel communications in WSNs helps to improve the overall performance of the network. However, in heavy traffic scenarios, routing protocols should be adapted to allow lo...

Cognitive radio, an upcoming technology gives the solution for the scarcity of spectrum where the transmitter acts as a sensible device which behaves as per the surrounding environment. A group of devices, which follows this technology, forms a temporary network called mobile cognitive radio ad hoc networks. The widely known ad hoc networks are always in moving fashion and there is no need for ...

Routing packets in multi-hop ad hoc wireless networks poses a great challenge mainly due to the unreliability of the wireless links and the inherent interference of the wireless medium [13]. Due to these characteristics, traditional wired routing schemes that select the best path towards a destination and forward the packet to a specific next hop, have proven ill-suited for networks utilizing t...

Opportunistic routing has increased the efficiency and reliability of Cognitive Radio Ad-Hoc Networks (CRAHN). Many researchers have developed opportunistic models, among them Spectrum Map-empowered Routing (SMOR) model, which is considered a more efficient model in this field. However, there are certain limitations SMOR, require attention resolution. The issue delay degradation packet delivery...

Wireless Sensor Networks are a research area of growing importance within the Wireless Networks research community. One of the major issues in this area is the search for efficient routing methods. Most of the routing algorithms developed so far are limited to single-sink scenarios with no or limited mobility. This paper presents a new routing approach, ODEUR (Opportunistic relative DistanceEna...

These Network Coding improves the network operation beyond the traditional routing or store-and-forward, by mixing of data stream within a network. Network coding techniques explicitly minimizes the total no of transmission in wireless network. The Coding-aware routing maximizes the coding opportunity by finding the coding possible path for every packet in the network. Here we propose CORMEN: a...

Since the packet is transmitted to a set of relaying nodes in opportunistic routing strategy, so the transmission delay and the duplication transmission are serious. For reducing the transmission delay and the duplicate transmission, in this paper, we propose the delay based duplication transmission avoid (DDA) coordination scheme for opportunistic routing. In this coordination scheme, the cand...

This paper proposes a data delivery method based on neighbor nodes' information to achieve reliable communication in a mobile ad hoc network (MANET). In a MANET, it is difficult to deliver data reliably due to instabilities in network topology and wireless network condition which result from node movement. To overcome such unstable communication, opportunistic routing and network coding schemes...
