Technological advances as well as the advent of 4G communications and of pervasive and ubiquitous computing have fostered a renewed interest in multi-hop (ad hoc) communications [1]. In particular, the interest is in self-organizing wireless multi-hop networks composed of a possibly very large number of nodes. These nodes can be either static or mobile, and are usually constrained as for the mo...

Multi-hop ad-hoc networks consist of nodes which cooperate by forwarding packets for each other to allow communication beyond the power range of each node. In pure ad-hoc networks, no additional infrastructure is required to allow the nodes to communicate. Multi-hop hybrid networks are a combination of ad-hoc and cellular networks. As in ad-hoc networks, the nodes forward packets on behalf of o...

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 ...

A wireless ad hoc network is a notable type of network in which a collection of mobile nodes with wireless network interfaces may form a temporary network, without use of any fixed infrastructure or centralized control. The Dynamic Source Routing protocol (DSR) is a efficient routing protocol explicitly designed for multi-hop wireless ad hoc networks of mobile nodes. A connected dominating set ...

—Ad-hoc networks are basically peer to peer multi-hop mobile wireless networks in which the information packets are transmitted in a 'store and forward' manner from a source to an arbitrary destination via intermediate nodes. The main objective of this paper is to evaluate the performance of various ad-hoc networks routing protocols viz.

In this paper, we propose an Optimized OSPF (Open Shortest Path First)protocol for MANETs (Mobile Ad-hoc Networks). MANETs are multi-hop ad-hoc wireless networks where nodes can move arbitrarily in the topology. The network has no given infrastructure and can be set up quickly in any environment. Traditional OSPF is not also well used in multi-hop wireless networks. The optimized OSPF we propos...

In this paper, we discuss the state of the art of (mobile) multi-hop ad hoc networking with the aim to present the current status of the research activities and identify the consolidated research areas, with limited research opportunities, and the hot and emerging research areas for which further research is required. We start by briefly discussing the MANET paradigm, and why the research on MA...

It is a great pleasure to introduce this special issue. Multi-hop ad hoc networks are collections of (mobile) nodes connected together over a wireless medium. These nodes can freely and dynamically self-organize into arbitrary and temporary , " ad hoc " network topologies. A mobile ad hoc network (MANET) is probably the most well-known example of this networking paradigm having been around for ...
