A Mobile Ad hoc Network is an infrastructure-less multi-hop wireless network. A node communicates directly with other mobile nodes within the wireless range and indirectly with nodes that are not within the wireless range of each other. Transmission power of the nodes plays an important role here. In a multi hop communication scenario, it is possible to minimize the total energy for reaching a ...

Mobile Ad-hoc networks (MANETs) are the only plausible choice when there is no infrastructure wireless network or it is too expensive to build one as in remote areas. They have the advantage of being quickly deployable. Routing is needed to find a path between the source and the destination and to forward the packets even if the destination node is out of range of the source node. In ad-hoc net...

The main characteristics of Mobile Adhoc NETwork (MANET) are no infrastructure, no centralized administration and self-configuring networks. The primary motivation of MANET deployment is to increase portability, flexibility and mobility but, mobility causes an unpredictable change in topology and makes routing more difficult. Efficient dynamic routing is a research challenge in such networks. I...

Mobile Ad hoc Networks (MANETs) are very considered attractive for many applications. Routing protocol is considered as the most important element of MANET. However, media streaming over MANET is a quite demanding task. In this paper the performances of MANET routing protocols have been investigated for video applications. Some popular routing protocols namely Dynamic Source Routing (DSR), Ad h...

In this paper we propose an ”on demand” multicast routing protocol for a wireless, mobile, multihop network. The proposed scheme has two key features: (a) it is based on the forwarding group concept (i.e., a subset of nodes is in charge of forwarding the multicast packets via scoped flooding) rather than on the conventional multicast tree scheme; (b) it dynamically refreshes the forward group m...

A Mobile Ad-hoc Network (MANET) is a collection of multi-hop wireless mobile nodes among which the communication is carried out without any centralized control or fixed infrastructure. MANET is a self-organized, self-configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The wireless link in the network are highly error prone and can go down frequently du...

Mobile ad hoc networks are envisaged to play a vital role in ubiquitous networking owing to their mobility support without relying on infrastructure-based design. Conversely, the same feature makes routing in these networks challenging as compared to the typical wired networks. As a result typical routing protocols designed for wired networks are not appropriate for these networks. A number of ...

This paper considers performance of mobile ad hoc network (MANET) routing protocols with respect to group and entity mobility models. The three widely used routing protocols have been investigated and compared: Destination Sequenced Distance Vector (DSDV), Ad-hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR). Mobility models encompass: Reference Point Group Mobility (RPGM), ...

A mobile ad hoc network (MANET) is a group of wireless mobile nodes dynamically shaping a provisional network devoid of the use of any existing network infrastructure or centralized management. In MANETs, security is the major challenge due to the dynamic topology which is because of the mobility of the nodes. In this paper, we propose a design and develop a secure methodology incorporated with...

A novel routing scheme for mobile ad hoc networks (MANETs), which combines the on-demand routing capability of Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a distributed topology discovery mechanism using ant-like mobile agents is proposed in this paper. The proposed hybrid protocol reduces route discovery latency and the end-to-end delay by providing high connectivity without ...
