High throughput data transfers across the Internet has become a challenge with deployment of data centers and cloud platforms. In this paper, we propose to utilize the cores of a router to build multiple abstractions of the underlying topology to parallelize end-to-end (e2e) streams for bulk data transfers. By abstracting a different graph for each core, we steer each core to calculate a different...
Typically, in low-power and lossy networks nodes communicate with servers over the Internet. Nodes collaborate wirelessly to relay their data to a gateway. A large-scale network can have multiple gateways. Selecting a proper gateway can have an immense impact on the network's performance. In this paper, we present joint routing and gateway selection protocols for low-power and lossy networks. To analyse...
The cooperation of heterogeneous unmanned systems, for instance, between aerial engines and terrestrial engines, relies on reliable communication. Data delivery is ensured by routing protocols, but traditional routing approaches, MANET and DTN, are not efficient in such networks. In this paper, we propose the S-ROGUE routing protocol combining the paradigms MANET and DTN and switching between them...
Because of the feature of hybrid wireless mesh network, hybrid routing protocol is the most proper routing protocol for this kind of network. Hybrid routing protocol is composed of proactive routing protocol and reactive routing protocol. The proactive one is adaptive for static mesh routers, and the reactive one is suitable for mobile mesh clients. Existing hybrid routing protocols all neglect the...
The article aimed at offering new ways of routing in networks with the DTN architecture, which allows using the most optimal routes for determining the routes depending on various conditions. To achieve these goals, it is necessary to analyze the available developments in this field with the subsequent identification of advantages and disadvantages. An attempt to realize advantages with a minimum...
Telecommunication networks have been designed and deployed with over-provisioning and redundancy of resources to cope with traffic load during peak hours and quickly recover from failure. However, most of these resources are underutilized and in most of the time idle but consuming full energy. With the growing concern of energy waste and greenhouse gases (GHG), the network design principles tend to...
It is becoming more and more obvious that the challenges regarding tactical radio communication cannot be met by a single static radio waveform. Instead, waveforms with different properties regarding range, robustness, and throughput need to be orchestrated. In order to benefit from the advantages of each radio technology integrated into the transparent tactical radio network, traffic engineering,...
Emulation environments are an effective approach to experimenting with and evaluating network protocols, algorithms, and components. This paper describes a joint effort by the NATO Science & Technology Organization's IST-124 Research Task Group to evaluate the scalability of OLSRv1 and OLSRv2 in an emulation environment within a military scenario. The scenario includes detailed mobility patterns...
Underwater Sensor Networks (USN) has a wide range of aquatic application that is totally different from terrestrial sensor network. The nodes of USN has a peculiar character tics like float mobility, limited bandwidth and energy, signal and link quality, routing challenges and its cost and high error probability. This nature if USN degrades the performance in terms of throughput and lifetime. This...
In this paper, we propose an interference-aware multicast routing scheme for a single-radio Wireless Mesh Networks carrying multiple multicast flows. We focus on multicast routing over WMNs with stationary nodes, such as community wireless networks. We present a new metric that is based on three components: Path Interference Cost (Ip), Broadcast Benefit Factor (BF), and Hop Count (HC). We proposed...
The fast topology changes in vehicular ad hoc networks (VANETs) may be caused by fading of the wireless link as well as mobility of nodes. Link stability is often measured using mobility parameters (e.g, location, velocity, direction), and disregarding multipath fading of the signal. This may cause network performances degradation. In this paper, we have improved the relay selection scheme by integrating...
Establishing trust relationships between routing nodes represents a vital security requirement to establish reliable routing processes that exclude infected or selfish nodes. In this paper, we propose a new security scheme for the Internet of things and mainly for the RPL (Routing Protocol for Low-power and Lossy Networks) called: Metric-based RPL Trustworthiness Scheme (MRTS). The primary aim is...

Although, it has not been possible to date, a development of routing algorithm addressing all the issues of WSN. Various tradeoffs exists...

In 6LoWPAN, RPL routing protocol is suggested by IETF standard to enhance the Quality of Service of data transfer that occurs between non-root node to root node. In this paper, the performance of RPL is analyzed in terms of Packet Delivery Ratio and Round Trip Time. The analysis is carried out to study the behavior of topology control strategy in 6LoWPAN. Hence, the analysis is executed on various...
The design of routing protocols for opportunistic networks (OppNets) generally assume that some cooperation prevail between the nodes. But, in the presence of non-collaborative attacks such as supernova and hypernova, the routing operations become a challenge. This paper proposes a defense mechanism against the misbehavior of supernova and hypernova nodes in an OppNet running Epidemic and ProPHet...
Wireless sensor networks (WSNs) are considered as the key technology for IoT (Internet of Things) applications thanks to their robustness and their deployment ease. The IPv6 Routing Protocol for Low power and Lossy Networks (RPL) is placed as the routing standard for multi-hop WSNs. However, RPL poorly adapts to sensor nodes' movement which rapidly alters the network performance. Therefore, we propose...
