It is crucial to guarantee content integrity in Named Data Networking(NDN), where copies of the contents are distributed over the network. NDN adopts digital signatures, and contents are verified whenever they are stored in caches. However, the current scheme is not practical in practice since its operations incur too much overhead. In this paper, we suggest a simple but effective solution for content...
This paper proposes a fully-distributed GMPLS framework through the use of extended RSVP-TE both for signaling and for routing, modulation and spectrum assignment (RMSA). Our proposed solution achieves lower blocking probability and shorter signaling-latency than does the state-of-the-art GMPLS/PCE architecture.
This paper investigates the communication network architectures for power systems between substations using IEC 61850. Optimized Network Engineering Tools (OPNET) is used for the simulations. The simulation results show the performance of individual architectures power system communications (PSC) for substation automation systems (SASs). Nowadays, interoperability among multi-vendor substations automation...
The nodes near sink in wireless sensor networks are featured with heavy transmission loads, so these performance bottleneck nodes are prone to running out of energy early with shortened network lifetime. Routing tactic plays important role on transmission performance and energy consumption of network. In this paper, we enumerate typical source routing tactics in Grid topology, include 1) Random Equal...
In this brief, a distributed impulsive algorithm for second-order multi-agent systems with a group reference velocity and input time delays is proposed. A distinctive feature of the algorithm is to address second-order consensus problems with local instantaneous interaction, where each agent can only exchange the information with its neighbors at a series of discrete-time instants and follow a desired...
The performance of web service could be influenced when network congestion appears. Methods of service migration can always reduce the communication cost especially when the service is popular and it takes up a lot of network resources. Many essential factors should be taken into account when we make the migration decisions, such as server load, delay, migration cost, etc. There are many strategies...
In this paper, the exponential topology identification for the uncertain complex dynamical network with time-varying coupling delay is studied via periodically intermittent control for the first time. By designing an periodically intermittent feedback controller, the unknown network topological structure is identified in the process of synchronization. Finally, an illustrative example is given to...
Routing is one of the most challenging aspects in Delay Tolerant Networks (DTN) because the end-to-end path does not always occur. In wildlife tracking, habitat monitoring, and other scenarios, the network area may be divided into some geographical communities, the nodes only move in their communities. In this paper, for this specific community-based DTN, we address the delivery delay of the epidemic...
A tree-based topology is often used to flood packets from the sink node in wireless sensor networks (WSNs). Therefore, flooding tree construction is an important and fundamental problem in WSNs, and has been extensively investigated in the literature. However, we note that the flooding tree construction problem in asynchronous low-duty-cycle WSNs has not been sufficiently investigated in existing...
