Mobile Ad Hoc Networks (MANETs) are multi-hop wireless networks in which all nodes cooperatively maintain network connectivity. In such a multi-hop wireless network, every node may be required to perform routing in order to achieve end-to-end communication among nodes. These networks are energy constrained as most ad hoc mobile nodes today operate with limited battery power. Hence, it is import...

Ad hoc networks are characterized by multi-hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. A mobile ad hoc network (Manet) is a collection of mobile nodes which communicate over radio. These kinds of networks are very flexible, thus they do not require any existing infrastructure or central administration. Therefore, mobile a...

This paper considers the throughput improvement issue in multi-hop ad hoc networks. We follow the approach that uses both multiple interface equipped nodes and multiple channels. The proposed solution enhances the routing protocol so that it selects routes that use multiple channels and alternate them at each intermediate node in order to reduce the intra-flow interferences. Then it adapts the ...

This paper presents an analytical Black Hole attack model to predict the mean packet loss of ad-hoc networks using reactive routing protocols without apriori knowledge of the actual topology configuration. Topology information is summarized as a set of prototypical hop-distance profiles that describe likely hop distance perspectives within the topology and are generated using K-means clustering...

Mobile ad hoc networks have gained a great deal of attention because of its significant advantages brought about by multi-hop, infrastructure-less transmission. This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. The Most of existing ad hoc routing protocols are susceptible to node mobility, mainly for large-scal...

Network coding technique increases wireless network communication efficiency. Wireless multihop relay network has been shown to achieve capacity gain over conventional single-hop wireless networks. Hybrid wireless relay networks integrate multihop ad hoc relay and infrastructure base stations to achieve better wireless network performance. Applying the promising network coding technique to hybr...

ad hoc mobile networks have dynamic topology with no central management. because of the high mobility of nodes, the network topology may change constantly, so creating a routing with high reliability is one of the major challenges of these networks .in the proposed framework first, by finding directions to the destination and calculating the value of the rout the combination of this value with ...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...

While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...

Wireless ad hoc networks enable over-the-air information exchange among (mobile) entities without a fixed infrastructure, and are very attractive for many commercial and military applications where pre-existing infrastructures are either infeasible or too expensive. However, this new form of communications poses new challenges to traditional networking architectures and protocols designed for w...
