To reduce energy consumption and extend lifetime is concernful in wireless sensor networks (WSNs). Besides, WSNs need to maintain coverage quality to capture the timely changed targets. A broad strategy is to select some sensors as working nodes to ...

Network Mobility (NEMO) Basic Support protocol is an extension Mobile IPv6. NEMO signaling is performed with extended of Mobile IPv6 messages. NEMO Basic Support protocol is concerned with managing the mobility of an entire network, it provides for ...

This paper proposes SCTPfx, a fast failover mechanism in SCTP multihoming. For data communication, SCTP uses a single path among multiple available paths in an association. This path is called the primary path. If the primary path fails, failover ...

This paper presents ORWAR, a resource-efficient protocol for opportunistic routing in delay-tolerant networks. Our approach exploits the context of mobile nodes (speed, direction of movement and radio range) to estimate the size of a contact window. ...

Many message routing schemes have been proposed in the context of delay tolerant networks (DTN) and intermittently connected mobile networks (ICMN). Those routing schemes are tested on specific environments that involve particular mobility complexity ...

One of the most important considerations in designing sensor nodes in a wireless sensor network is to extend the network lifetime by minimizing the energy consumption with limited resources. The most challenging aspects of the studies conducted on this ...

Bittorrent is currently one of the most popular peer-to-peer (P2P) file sharing protocols. However, it incurs such excessive amount of traffic that it may adversely affect users of legacy internet applications. To limit this adverse impact, an efficient ...

Users, application services, single files and files collections, computers, detachable memory, distributed network storage -- this is far from being the comprehensive list of thinkable today networked objects. More importantly, all of these objects can ...

In this talk, the theory of network calculus is discussed from the point of view: (1) how powerful it is in applications as well as (2) what fundamental challenges it still faces before it can be considered a similarly mature theory as the well-known ...

Comparing to the client based locating, infrastructure based methods do not require install special software or hardware at client side. So it not only fits for real deployment, but also supports some specific requirement (ex target tracking). Former ...

Integration of WLAN hotspots into next generation cellular networks requires considerations on location management, resource allocation, handoff algorithms and their sensitivity to mobility related features such as velocity of the mobile and the handoff ...

Project DUMBO (Digital Ubiquitous Mobile Broadband OLSR) deploys Mobile Ad Hoc Network (MANET) for post- disaster situations where fixed network infrastructure is unavailable; an emergency network has to be put in place urgently. DUMBO allows streaming ...

Hands-on experiences are indispensable to train IT operators. However, it is often difficult to conduct hands-on practices in many locations due to lack of resources such as PCs and network equipments. The cost of gathering lecturers and participants at ...

This paper discusses the possibility of applying an image-processing technique to detecting anomalies in Internet traffic, which is different from traditional techniques of detecting anomalies. We first demonstrate that anomalous packet behavior in ...

Analysis of AS-level topologies is an effective way to understand the Internet structure and its development. An AS topology represents logical connection relationships of networks, and thus, is independent of geographic locations of connections. ...
