An ad hoc network is characterized by frequent changes in the network topology, limited bandwidth availability, and limited power of nodes. The ad hoc network topology changes frequently as nodes are able to move collectively or individually and often in an unpredictable way. When one node moves out of or into the transmission range of another node, the wireless link between the two becomes dow...

Dynamic spectrum access is an attractive area of research these days. Cognitive Radio (CR) enabled networks are being deployed to effectively utilize the RF spectrum. Wireless mesh networks have been experiencing the bandwidth scarcity but such networks can easily enhance their throughput by using the CR transceivers as these networks have the capability of multipath routing. Existing routing p...

Mobile Ad hoc networks (MANETs) are self organized by a collection of mobile nodes, which are interconnected by multi hop wireless paths. Providing QoS support in MANETs is an active research area, basically for supporting real time applications that are based upon interaction between the routing scheme and QoS provisioning. The goal of QoS aware routing is to achieve more deterministic behavio...

A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formulated without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing protocol that adapt to the frequent and randomly changing network topology. Several attacks are possible in the available routing protocols such as Wor...

Vehicular Mobile Communication has emerged as a new area of attraction in the field of Wireless communication. VANETs have emerged as a boon towards saving human live by its safety and non-safety potential applications. This paper tests routing protocols namely Ad hoc On Demand Distance Vector (AODV), Ad hoc On Demand Multipath Distance Vector (AOMDV), Dynamic Source Routing (DSR) and Destinati...

Multipath routing allows building and use of multiple paths for routing between a source-destination pair. It exploits the resource redundancy and diversity in the underlying network to provide benefits such as fault tolerance, load balancing, bandwidth aggregation, and improvement in QoS metrics such as delay. There are three elements to a multipath routing, namely, path discovery, traffic dis...

The multipath route establishment uses the method that discovers multiple multi hops communication between source and destination. Multi-path routing can balance the load better than the single path routing in ad hoc networks, thereby reducing the congestion by dividing the traffic in several paths. This research presents a new approach of Multipath Load Balancing with AOMDV routing protocol an...

Due to mobile nature of the nodes and unreliable wireless channels for data transmission, frequent link failures occurs in mobile ad-hoc networks (MANET). This leads to research in multipath extension of the routing protocols. This paper proposed a link-disjoint multipath AODV (LD-MPAODV) routing mechanism to increase the robustness of routing process in MANET. The objective of the proposed rou...

A Mobile Ad-hoc Network (MANET) consists of a number of mobile nodes. These mobile nodes can communicate without any centralized control mechanism. MANETs are self-organizing and selfconfiguring multi node wireless networks without any infrastructure. In MANET the structure of the network changes dynamically. The fundamental characteristic of MANETs which differentiate it from other wireless or...

An important and essential issue for mobile ad-hoc networks (MANETs) is routing protocol design i.e. a major technical challenge due to the dynamism of the network. The work of this paper is inspired by the thought of taking account of several factors in wireless mobile ad-hoc networks (MANETs) routing design in a unified way. The rational of our inspiration is that most of the enhancements in ...
