Locating objects with topology-independent identifiers has emerged as a key functionality in data and information centric approaches to networking. Numerous designs have been proposed to address the obvious scalability and efficiency challenges such systems face in Internet-scale deployments. However, dealing with evolvability and deployability concerns in environments encompassing multiple adm...

-Geocast is a variation of traditional multicast. It realized the forwarding of messages from source node to the nodes residing at specified geographic areas often referred to as a Geocast region. This paper describes a new scenario of Geocast protocol in which a source node locating outside the mobile ad hoc network sends packets to all sensor nodes within a specified geographical region in or...

The paper introduces two software tools for planning and operating an urban logistic center. The former software, called DiLog, is devised to determine the optimal assignment of delivery points to several possible terminals. It allows so the planner locating and sizing the terminals of the urban logistic system. Dylog is a dynamic software tool that allows the manager of an urban logistic base ...

Browsing is a way of finding documents in a large amount of data which is complementary to querying and which is particularly suitable for multimedia documents. Locating particular documents in a very large collection of multimedia documents such as the ones available in peer to peer networks is a difficult task. However, current peer to peer systems do not allow to do this by browsing. In this...

In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...

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...

Location-Routing Problem (LRP) is related to logistics system of supply chain. In LRP, aims are facility location problem and vehicle routing problem that are considered simultaneously. As shown in recent researches, the costs in distribution systems may be excessive if routes are ignored when locating depots. In this paper, a heuristic method in four phases is developed to solve Capacitated Lo...

Recent multicast routing protocol proposals such as protocol independent multicast (PIM) and core-based trees (CBT) have been based on the notion of group-shared trees. Since construction of a minimal-cost tree spanning all members of a group is difficult, they rely on center-based trees and distribute packets from all sources over a single shortest-path tree rooted at some center. PIM and CBT ...

Many multicast applications, such as video-on-demand and tele-education, desire quality of service (QoS) support from the underlying network. Recently, many QoS-based multicast protocols have been proposed to meet this requirement. However, few of them can achieve high success ratios while maintaining good scalability. In this paper, we propose a new QoS-aware multicast protocol based on a boun...
