wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Submitted: May 11, 2013; Accepted: Jun 18, 2013; Published: Jun 30, 2013 Abtract: The expansion in Ad-hoc wireless network and vehicular Ad-hoc networks, it is expected that traffic data will be collected and dispersed in real time by mobile sensors as a alternative of fixed sensors infrastructure. Routing in vehicular Ad-hoc networks is a challenging field of interest, due to high speed and ci...
A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Multi-hop routing and beaconing approaches are two important research challenges in high mobility vehicular networks. Routing protocols are divided into two categories of topology-based and position-based routing protocols. In ...
Consider a wireless sensor network consisting of n wireless sensors randomly distributed in a twodimensional plane. In this paper, we show that with high probability we can locally find a path for any pair of sensors such that the length of the path is no more than a constant factor of the minimum. By assuming each sensor knows its position, our new routing method decides where to forward the m...
Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...
Mobility Prediction Progressive Routing (MP2R), a Cross-Layer Design for Inter-Vehicle Communication
In this paper we analyze the characteristics of vehicle mobility and propose a novel Mobility Prediction Progressive Routing (MP2R) protocol for Inter-Vehicle Communication (IVC) that is based on cross-layer design. MP2R utilizes the additional gain provided by the directional antennas to improve link quality and connectivity; interference is reduced by the directional transmission. Each node l...
Routing in Mobile Ad-Hoc Network (MANET) is a crucial task due to highly dynamic network environment. In latest years, several routing protocols have been implemented. In recent developments, position-based routing protocols exhibit better scalability performance and robustness against frequent topological changes such as, Location-Aided Routing (LAR) protocol. In this paper, developments of pe...
This paper addresses mobility control routing in wireless networks. Given a data flow request between a source-destination pair, the problem is to move nodes towards the best placement, such that the performance of the network is improved. Our purpose is to find the best nodes selection depending on the minimization of the maximum distance that nodes have to travel to reach their final position...
The management in mobile ad hoc networks is quite challenging as compared to management in wired networks. Several management strategies have been proposed by authors using either pro-active or reactive routing protocols. In this paper, we propose a policy-based management framework for ad hoc networks in which policy servers can efficiently communicate and service their clients using Location-...
In the past few years mobile ad-hoc networks came increasingly into scope of interest. Mobile ad-hoc networks are mainly confronted with the problems of unknown topologies as well as mobility. Several approaches to support functionality and reliability under such conditions have been pronounced. One group of such schemes is based on the network participant’s location information. Furthermore, m...
