One common design for routing protocols in mobile ad hoc networks is to use positioning information. We combine the class of randomized position-based routing strategies called AB (Above-Below) algorithms with face routing to form AB:Face2:AB routing algorithms, a new class of hybrid routing algorithms in mobile ad hoc networks. Our experiments on unit disk graphs, and their associated Yao sub-...

A MANET is a self configuring infrastructure less networks. It is usually connected by wireless. Each device in a MANET is independently to move in any direction. To maintain neighbor position the geographic location coordinates of the node is a famous method used by most geographic routing protocol for the purpose of periodic broadcasting of beacon packets. If the location information is not a...

Efficient and practical communications between large numbers of vehicles are critical in providing high level of safety and convenience to drivers. Crucial real-time information on road hazard, traffic conditions and driver services must be communicated to vehicles rapidly even in adverse environments, such as “urban canyons” and tunnels. We propose a novel routing protocol in vehicular network...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

using greedy clustering method to solve capacitated location-routing problem with fuzzy demands abstract in this paper, the capacitated location routing problem with fuzzy demands (clrp_fd) is considered. in clrp_fd, facility location problem (flp) and vehicle routing problem (vrp) are observed simultaneously. indeed the vehicles and the depots have a predefined capacity to serve the customerst...

Vehicular Ad Hoc Networks (VANETs) have attracted the interest of the scientific community, since many issues remain open, especially in the research area of routing techniques. In this work we propose a new position-based routing algorithm called Junction-Based Routing (or JBR). The algorithm makes use of selective greedy forwarding up to the node that is located at a junction and is closer to...

The development in technologies the mobile networks has been rapidly change, especially Mobile Ad-hoc and Vehicular Ad-Hoc networks. Due to nature of the fields, the mobile sensor network replaced the fixed sensor network. In these fields, the topology dynamically changes time by time due to speed and congested environment because of this routing is a crucial and challenging issue. For routing ...

Vehicular Ad hoc Networks (VANETs) allow vehicles to form a self-organized network without any fixed infrastructure. VANETs have received wide attention and numerous research issues have been identified in the recent time. The design and implementation of efficient and scalable routing protocols for VANETs is a challenging task due to high dynamics and mobility constraints. In this paper, we ha...

MANETs are infrastructure free network, hence are mostly vulnerable to attacks and maintaining the anonymity of the nodes is also becoming a major concern. Most of the existing geographical routing methodology in Mobile Ad Hoc Networks (MANET) does not include any position update mechanism for anonymous mobile nodes. In this paper, we propose a secure geographical routing which uses an adaptive...

The efficiency of routing protocols in general mobile ad hoc networks may be highly affected by the specific Medium Access Control scheme the routing relies upon and by the mobility of the wireless nodes. In this work, we address the design of position based routing solutions for the support of safety oriented applications in Vehicular Ad hoc NETworks (VANETs) by focusing on the impact of the M...
