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...

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...

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...

Many ad hoc network protocols and applications assume the knowledge of geographic location of nodes. The absolute location of each networked node is an assumed fact by most sensor networks which can then present the sensed information on a geographical map. Finding location without the aid of GPS in each node of an ad hoc network is important in cases where GPS is either not accessible, or not ...

Ad-hoc networking capabilities have provided the flexibility needed to construct various types of networks without infrastructure base stations. Emerging products for sensor networks, such as Zigbee (1), use ad-hoc networking capabilities to construct networks. These sensor nodes can construct the network such as in outdoor fields and inside buildings without much effort on establishing the bas...

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 ...

In this paper, a new routing protocol for Mobile Ad-Hoc networks (MANETs) is presented; the proposed power-hop based Ad-hoc on demand Distance Vector (AODV) is named PH-AODV, it uses the node power and the hop count parameters to select the best routing path. This paper compares the performance of the proposed PH-AODV in terms of average delay, average dropped packets and average throughput. Re...

Ad hoc wireless networking is currently a hot research area, especially because there is an increasing need for connectivity “anywhere” and, in particular, “anyhow.” While traditional networks have fixed nodes with wired connections (either optical fibers or copper lines), ad hoc wireless networks can be described as multi-hop wireless networks with mobile nodes. However, the mobility condition...

This work presents a new architecture, Multihop Cellular Network (MCN), for wireless communications. MCN preserves the benefit of conventional single-hop cellular networks (SCN) where the service infrastructure is constructed by fixed bases, and it also incorporates the flexibility of ad-hoc networks where wireless transmission through mobile stations in multiple hops is allowed. MCN can reduce...
