Balancing the load in content addressing schemes for route-restricted networks represents a challenge with a wide range of applications. Solutions based on greedy embeddings maintain minimal state information and enable efficient routing, but any such solutions currently result in either imbalanced content addressing, overloading individual nodes, or are unable to efficiently account for network dynamics...
The backpressure algorithm has been widely used as a distributed solution to the problem of joint rate control and routing in multi-hop data networks. By controlling a parameter V in the algorithm, the backpressure algorithm can achieve an arbitrarily small utility optimality gap. However, this in turn brings in a large queue length at each node and hence causes large network delay. This phenomenon...
We introduce structural transformations that allow simplifying a given network while preserving its original “bandwidth” and “routing” capabilities, transparently to specific allocations. We minimize a certain objective such as the aggregate capacity of network links, number of nodes, or number of links, in such a way that all the bandwidth that could be routed in the original network can also be...
Nowadays, there is a fast-paced shift from legacy telecommunication systems to novel Software Defined Network (SDN) architectures that can support on-the-fly network reconfiguration, therefore, empowering advanced traffic engineering mechanisms. Despite this momentum, migration to SDN cannot be realized at once especially in high-end cost networks of Internet Service Providers (ISPs). It is expected...
Wireless devices such as sensors have increasingly more processing, storage, and networking capabilities, making wireless sensor networks (WSNs) get lots of attentions in recent years. In addition, the cost of sensors is constantly decreasing making it possible to use large quantities of these sensors in a wide variety of important applications in environmental, military, commercial, health care,...
In this poster, we consider software-defined wireless sensor networks (SDWSNs) and present a lightweight flow management to reconfigure flow entries in flow-table when link fault occurs in the data plane of SDWSNs.
While acoustic signals are still the main communication means under water, other technologies are being developed, e.g., based on optical and radio-frequency electro-magnetic waves. Each technology has its own advantages and drawbacks to trade off, e.g., communication range vs. bit rate. Recently, new approaches are emerging to leverage the advantages of several underwater technologies by incorporating...
In this article, we consider software-defined wireless sensor networks (SDWSNs) and propose a scheme for sleep scheduling with low control overhead-based flow-entry in flow-table to overcome the limitation of control traffic in SDWSNs.
Store-carry-and-forward is extensively used in vehicular environments for many and varied purposes, including routing, disseminating, downloading, uploading, or offloading delay-tolerant content. The performance gain of store-carry-and-forward over traditional connected forwarding is primarily determined by the fact that it grants a much improved network connectivity. Indeed, by letting vehicles physically...
Power consumption and CO2 emission have become a major concern over the last few years. Several recent studies have shown that servers and network equipments consume up to 45% of the energy consumption of data centers [1]. Software-defined networking is a new networking paradigm that decouples the control and data functionalities; thus, makes networks easily manageable and programmable. In software-defined...
The Internet consists of a large number of interconnected heterogeneous ASs (Autonomous Systems), each owned and administered by an autonomous organization. Traffic in each AS is forwarded by routers that maintain a coherent picture of the network topology using an intra-AS routing protocol. The most popular intra-AS routing protocols are link-state protocols, such as OSPF and IS-IS. An attacker who...
In this paper, we present the Context-Aware Opportunistic Resource-Based Routing Protocol (CORB) for intermittently-connected stationary wireless sensor networks. This protocol targets domains such as ambiance control in smart buildings. Unlike existing context-aware routing approaches which consider node mobility as the main source of disconnection, CORB only considers the nodes' limited resources...
While the threats in Internet are still increasing and evolving (like intra multi-tenant data center attacks), protection and detection mechanisms are not fully accurate. Therefore, forensics is vital for recovering from an attack but also to identify the responsible entities. Therefore, this paper focuses on tracing back to the sources of an anomaly in the network. In this paper, we propose a method...
Detecting and handling routing loops is a critical issue in the design of anonymous peer-to-peer content sharing networks (apCSNs). A principal requirement of such a scheme is that it should not leak any message forwarding information that can undermine the user anonymity of the resulting apCSN. A number of loop handling schemes have been developed in apCSNs such as Freenet and GNUnet. However, they...
This paper has analyzed routing selection errors in the process of two-way redistribution among different routing protocols in the large network architecture. The network device simulation software is used to state routing selection errors in the redistribution process between the protocol of RIP and OSPF. It also predicts the possible problems. Through the access control list, we will obtain the...
To efficiently exploit network resources operators do traffic engineering (TE), i.e., adapt the routing of traffic to the prevailing demands. TE in large IP networks typically relies on configuring static link weights and splitting traffic between the resulting shortest-paths via the Equal-Cost-MultiPath (ECMP) mechanism. Yet, despite its vast popularity, crucial operational aspects of TE via ECMP...
Simultaneously providing flexibility, evolvability and correctness of routing is one of the basic and still unsolved problems in networking. Route redistribution provides a tool, used in many enterprise networks, to either partition a network into multiple routing domains or merge previously independent networks. However, no general technique exists for changing a live network's route redistribution...
As chip density increases rapidly with every process generation, the use of Network-on-Chip (NoC) has become the prevalent architecture for SoC, MPSoC, and, large scale CMP (Chip Multi Processor) based designs. Diverse NoC solutions have been proposed by the researchers to meet the enhanced on-chip communication requirements. Here, underlying network interconnection architecture (topology), router...
This paper introduces a new implementation of Shared Segment Protection (SSP) in mesh communication networks, in which a novel Integer Linear Program (ILP) is proposed under a reduced amount of routing information. In particular, the scheme of Distributed Partial Information Management with Sufficient and Aggregated Information (DPIM-SAM) [1] will be adopted for trading the optimality with the reduction...
Network-on-chip (NoC) is emerging as an effective architecture which address the shortcomings of traditional bus-based System-on-chip (SoC). Since its better properties, such as the lower power consumption, smaller size and higher scalability, mesh is often regarded as an effective topology for NoC design. In this paper, we propose a double-layer sparse honeycomb topology as a terrific design option...
