In virtue of its widespread application scenarios, especially in battlefield communication, disaster rescue, satellite and deep-space transmission, Delay-disruption Tolerant Network (hereinafter referred to as DTN) has become one of the most attractive focuses in research for future Internet. Due to the intermittent connectivity, mobility of nodes, signal interference, jamming in DTN, there exist...
Recently, the significantly increased IPv6 address length has posed a greater challenge on wire-speed router for packet classification (PC). Most conventional IPv4-based PC algorithms are no longer suitable for IPv6 PC. The performance and capacity of many IPv6 algorithms and classification devices depend upon properties of the IPv6 classifiers. However, there are no publicly available IPv6 real classifiers...
A wireless mesh network (WMN) is a collection of wireless network nodes that communicate among themselves. Unlike wireless local area networks, WMNs are self configuring systems, where each node can relay messages on behalf of others. This allows coverage of a much larger geographical area than if all nodes needed to be able to communicate directly with a central node. WMNs promise to deliver wireless...
Recent years, the mobile ad hoc networks (MANETs) research community has been very active. Thus, it is of growing importance to build distributed network applications on top of MANETs. DHT is known as a popular technique to build efficient distributed applications in the Internet. However, in MANETs, DHT needs to consider network traffics, moving of nodes and energy efficiency more carefully than...
Ad hoc networking allows portable devices to establish communication independent of a central infrastructure. The Integration of the MANETs and infrastructure networks such as Internet extends the network coverage and increases the application domain of the MANET. Communication between a mobile device in an ad hoc network and a fixed device on the Internet is achieved using gateways, which acts as...
Traffic driven based load balancing routing scheme in CogMesh network is proposed. SMC (secondary mesh client) accessing to CMR (cognitive mesh router) using Ad Hoc way is considered in the paper. A novel routing metric was proposed to describe the load state of a path, which was suitable for traffic demand. Choosing a light-loaded route and a light-loaded link guarantees a lower end-to-end delay...
The Internet access from vehicular networks is gaining great interest from the research community. In fact, vehicles should be able to connect to the Internet and communicate with different networks through gateways. Guaranteeing safety on the roads is the main objective of vehicular networks. Safety applications need to collaborate with other types of services for efficient safety assurance. Consequently,...
The NEMO basic support protocol is a home agent based technique (derived from mobile IPv6) that permits the mobility of a network of IPv6 devices to be supported through the use of a dedicated mobile router. This NEMO mobile router accepts connections from IPv6 nodes and transparently manages any IP mobility on their behalf, which means that as well as individual hosts, a NEMO mobile router can also...
Inter-domain routing for MANETs (mobile ad hoc networks) draws increasing attention because of military and vehicular applications. The existing border gateway protocol (BGP) is the de facto inter-domain routing protocol for the Internet. But BGP is not applicable to MANETs because the BGP design is based on a static Internet which does not support dynamic discovery of members, and cannot scale to...
This paper presents the design of an universal intelligent vehicular ad-hoc network (InVANET). The network is widely scalable and interoperable with other networks including cellular networks, public switched telephone networks (PSTN) and Internet. Hence, we denote these newly designed mobile environments as universal mobile ad-hoc system (UMAS). The InVANET backbone is constructed from a hierarchical...
In framework for integrating Internet and MANET, because the equipments in the networks are fixed, there is no need to consider the problem of energy. In MANET (mobile ad hoc network), the energy of the mobile nodes will affect the life time and the performance of the network, so it must consider the load and energy of a node. This paper proposes a new routing method called Load balancing and asymmetrical...
Incorporating multi-hop ad hoc wireless networks in the IP infrastructure is an effort to which a growing community participates. One instance of such activity is the extension of the most widely deployed interior gateway routing protocol on the Internet, OSPF (Open Shortest Path First), for operation on Mobile Ad hoc Networks (MANETs). Such extension allows OSPF to work on heterogeneous networks...
There is an increasing acceptance for Wireless Mesh Networks (WMN) as the potential `last-mile' access technology running media-rich applications with stringent quality of service (QoS) requirements. As WMNs are envisioned to provide high bandwidth broadband services to a large community of users, the Internet Gateway which acts as a central point of attachment for the mesh routers is likely to be...
In mobile social networks (MSN) individuals with similar interests or commonalities connect to each other using the mobile phones. MSN are special kind of ad-hoc networks in which wireless connectivity (i.e. encounters and re-encounters) with social peers is predictable. Most of the recent research proposes routing framework to exploit these predictable patterns to identify the best information carriers...
The main contribution of this article is to propose a collaborative and distributed cache mechanism tailored for ad hoc networks. Each node's cache is partitioned into a shared area and a private area. The proposed collaborative cache is formed by each node's shared area, which is used to store contents relevant to the group, while the private area is used to store information relevant to its owner...
Wireless mesh network is a new broad bandwidth distributing wireless access network system. It can access Internet through gateway nodes. When network load of access is heavy or network size is expanding, one gateway node will become a bottleneck of the access network because of the serious congestion of a large number of data packets transmitted to the gateway node. Based on the research of DSR (dynamic...
The availability of Internet services brings many benefits to developing regions, yet Internet deployment levels in these regions remain staggeringly low. In this work we investigate how existing cellular deployments, which have enjoyed more rapid and wider deployment than client Internet infrastructure, could be used to provide very low cost Internet services in underdeveloped rural areas. We propose...
Wireless mesh networks are mobile communication networks where the nodes may have fixed or mobile relative position among each other. The application range is large, they can be used either as a sensor network or connected to Internet through gateways. The communication is carried over low power and low range wireless channels, so its necessary a multi hop routing. The Better Directed Progression...
A key challenge in multihop wireless network is to provision for sufficient network capacity to meet user requirements. The contributions of this paper are two-fold: (a) we analyses wireless bandwidth, the ratio between the number of channels and the number of interfaces, the ratio between the number of gateways and the number of mesh routers, and the impact on the capacity of mesh backbone, and present...
Driven by the idea to converge to the Internet of things, we searched within the course of a FP6-project for a suitable mechanism to transport IP packets on ad-hoc wireless personal area networks (WPANs). Prior work was already done and so we decided to start with RFC4944, which was probably the best working solutions for this problem. But since the design of RFC4944 was only targeted to a point-to-point...
