Service discovery is an integral part in establishing an independent and self-organizing mobile ad-hoc network(MANET). In this paper a new distributed semantic service discovery scheme is proposed for MANET consisting of various mobile terminals. The proposed scheme based on the proactive routing protocol, Destination-Sequenced Distance Vector (DSDV), maintains the information on the network in the...
This work proposes a novel packet urgency metric-based cross-layer design of packet scheduling and routing algorithms to effectively deliver video streaming data over mobile ad hoc networks based on IEEE 802.11 multi-rate service. First, the packet urgency, node urgency, and route urgency are defined on the basis of the residual time to the destination. Furthermore, the one-hop transmission delay...
This paper presents a multicast routing mechanism supporting the classical IP multicast service model that can dynamically use redundant forwarding in the parts of the network affected by a high rate of topology changes, while converging to regular multicast distribution trees where or when the network becomes relatively stable. The rationale is that intermittent connectivity directly affects the...
We present a new approach to performing adaptive, loop-free, destination-based unicast forwarding in an IP-based network. The approach is an integration of several well-known techniques, including broadcast-based flooding, on-demand route discovery, and link state routing. In this approach, routers are not universally in one routing mode, such as a ‘link-state’, for all destinations but instead apply...
In tactical environment, MANET (Mobile Ad Hoc Network) has the network characteristics which make highly dynamic nodes, self-organized in fully-distributed style. Also, it has a harsh wireless channel environment compared to the commercial networks. In these channel environments, optimal path decision suited for Quality of Service (QoS) of transmitted tactical traffics must be performed by recognizing...
Recently developments in the field of telecommuni-cations and network technology has been formed new paradigm shift in defense weapon system. The military also developing the Tactical Information Communication Network (TICN) system to meet the changing aspects of these wars. To equip its function from the battlefield, TICN system have to be received real-time information from the battlefield troop,...
A Mobile Ad-hoc Network (MANET) is actually a set of nodes which are self-configured and organized dynamically. Furthermore, nodes can communicate with each other without any fixed infrastructure as the base stations. The Ad-hoc On demand Distance Vector (AODV) is the most typical reactive routing protocol in MANET. It has been extensively studied through not only computer simulations but also implementations...
In this paper, we propose a new multi-path routing protocol in MANET that is composed of high-mobility nodes. The new multi-path routing establishes the main route by the mechanism based on AODV, and then the data transmission starts immediately. The backup route search process is taking place while data is transmitted to reduce the transmission delay. This process finds the route that is node-disjoint...
IEEE 802.11 is one of the wireless network MAC/PHY protocols. Though IEEE 802.11 a/b/g offers more than one non-overlapping channels, IEEE 802.11 a/b/g uses just one channel for communication. These days, NICs(Network Interface Cards)'s cost has been decreasing and its performance has been increasing. Therefore, the mobile nodes are able to use more than one interface and many channels simultaneously...
In this paper, we studied the multi-hop broadcast algorithms for delivery of safety message in inter vehicle communication environment. In MANET environment, there are three multi-hop broadcasting schemes such as probability based methods, area based methods and topology based methods. We simulate MANET based multi-hop broadcasting schemes and evaluate the performance of our work in order to analyze...
Emergency Telemedicine Service (ETS) is used efficiently for treatment to the wound patient in disaster areas. However, ETS cannot be used if the primary network channel is unavailable due to unexpected damages on the communication infrastructures, and increased network traffics. We established the Mobile Ad hoc Network (MANET) based on Wireless LAN (WLAN), and developed software program implemented...
This paper proposes a method of improving the efficiency of P2P(peer-to-peer) content sharing services like BitTorrent using the network information in the mobile ad hoc network (MANET) environment. While many papers focus on P2P information dissemination and searching in the MANET environment, this paper focuses on the P2P data delivery strategy. This strategy involves peer selection and piece selection...
A MANET comprises a set of mobile devices which are capable of communicating with others. Despite its flexibility and portability, it suffers from energy limitation. If the energy consumption of the nodes in the MANET cannot be balanced efficiently, some nodes will die in an early stage due to the energy depletion, which in turn partitions the whole network and leads to the communication failure....
It is important to analyze link status changes in mobile ad hoc networks (MANETs) since the wireless channel is affected by multiple sources of interference. Scalability is a major research topic in the development of MANET routing algorithms, since the network resource of MANET is limited due to the contention-based wireless communication channel. This paper proposes to adopt a dominant pruning (DP)...
A MANET (Mobile Ad-hoc Network) is a multi-hop routing protocol formed by a collection without the intervention of infrastructure. So the MANET also depended on the property as like variable energy, high degree of mobility, location environments of nodes etc. In recently years, the various clustering technique and routing algorithm would have proposed for improving the energy efficiency. One of the...
We present CORE (common open research emulator), a real-time network emulator that allows rapid instantiation of hybrid topologies composed of both real hardware and virtual network nodes. CORE uses FreeBSD network stack virtualization to extend physical networks for planning, testing and development, without the need for expensive hardware deployments. We evaluate CORE in wired and wireless settings,...
IP traceback in MANET (mobile ad-hoc network) is more difficult than in traditional wired network because of the dynamically-changing topologies and limitation in resource. Researches in IP traceback for MANET largely follow the similar approaches as in the wired network and are having difficulties in overcoming the above mentioned topology and resource limitation problem. We suggest to cope with...
Ad hoc network is a multi-hop wireless network formed with non-infrastructure. The fact that limited resource could support the network of robust, simple framework and energy conserving etc. In this paper, we propose a new ad hoc multicast routing protocol for based on the ontology scheme called inference network. Ontology knowledge-based is one of the structure of context-aware. And ontology clustering...
In this paper, we present minimizing the maximum used power routing algorithm (MIVIPR) in mobile ad hoc network (MANET). Most previous energy aware routing protocols usually optimize just one optimization criterion, which minimizes the total used energy or evenly distributes power consumption in each node to prevent node from being over exhausted. MMPR achieves two optimization objectives using a...
