Wireless sensor networks are comprised of a group of nodes, which are randomly distributed in an environment. Since the energy consumptions of nodes are limited in these networks, data should be collected and sent optimally and in an energy-efficient way. The available routing protocols are used to send data in this way. The main responsibility of these protocols is to reduce energy consumption and...
Underwater Wireless Sensor Network (UWSN) is emerging lots of attention due to its various types of characteristics and applications. Distinctive underwater characteristics leads to many challenges such as-high propagation delay, data losses, nodes mobility, localization, nodes deployment while designing any reliable and efficient routing protocol. In this paper, an extension of CDBR (Forwarding nodes...
Software-Defined Networking (SDN) is a recent model of networking architecture which splits the network control from data forwarding functions. Most SDN solutions have in their scope the wired networks, but more recently, some attempts have been made to adapt SDN architecture for the context of wireless mesh networks (WMNs). In the present paper, we examine whether the use of the SDN paradigm in WMNs...
This paper studies the fault management in mobile ad hoc networks. We focus on schemes which provide the robustness in MANETs: service restoration and service protection. Firstly, we propose an analytical comparison of service restoration, in terms of restoration time, at the routing layer (reactive and proactive protocols). Service restoration with reactive protocol is the most suitable in MANETs...
The design of a trust management framework in a mobile ad hoc network and its various components to protect against different attacks has a significant impact upon the performance of the secure routing protocol which is meant to form the most reliable route for data delivery. Specifically, the current work focuses upon the impact of certain parameters specific to two components within the proposed...
Low Power and Lossy Networks (LLNs), as it covers a wide scope of applications, such as building automation, industrial control, healthcare etc., has received considerable attention in recent years. In many LLNs applications, Point-to-point (P2P) communication is crucial, which extremely need to be supported by reliable and energy- efficient routing protocols. However, traditional routing protocols...
It does not seem easy to generate reliable routes in Vehicular Ad-hoc Networks (VANETs) because of frequent link failures caused by vehicle's mobility. In this regard, we analyze the characteristics of topology-based routing protocols in order to assess the feasibility of each protocol for vehicular environments. We plan to design an efficient routing protocol for VANETs in order to generate reliable...
Mobile Ad Hoc network works in hostile environment in absence of central control. Malicious or low energy nodes may degrade performance and also affects lifetime of the network. Broadcasting method which is commonly used for maintaining connectivity causes high overhead on the network. So it is necessary to exclude malicious and low energy nodes from the network and reduce the overhead. The proposed...
With the increasing development of technologies and reducing costs of materials, satellite networks have been widely investigated both on demand and supply for many years. Multi-Path routing has been applied as an effective method to support end-to-end reliability. But there exist inter-satellite links loss and long end-to-end delay in current multi-path routing due to much frequency of route request...
The acoustic environment suffers from a number of impairments which effect transmitted data reliability and integrity leads toward low-quality routing. Integral part of cooperative routing is reliable data delivery with trade-off energy consumption is high, because of multiple transmissions. In order to overcome this problem and getting advantage of cooperation routing, we proposed a scheme Sink Mobility...
Cooperative Beamforming is a flourishing technique to resolve many issues related to Cognitive Radio Networks. One of them is to overcome the problems caused by failure of several nodes in a network. In case of node failures, the optional paths are selected instead of intended paths which may cause additional delay. This work suggests a route conservation protocol with minimal changes in a basic routing...
Vehicular Adhoc Networks (VANETS) enable the vehicles to communicate with each other as well as with road side units. But developing an efficient routing for these networks potentially due to the large mobility and regular changes in these networks is a challenging job. In VANETS transmission links are at the risk of disconnection. Thus the development of the efficient routing mechanism is needed...
Multipath interference or route coupling is a severe issue in multipath routing schemes of wireless sensor networks. Due to that, quality of data transmission is impossible in wireless sensor network (WSN) or heterogeneous wireless sensor network (HTWSN). Multipath routing is having many features over single path routing, but it is highly prone to multipath interference. The existing multipath routing...
With the rise of drones, providing a strong connectivity to the drones has become an indispensable part. Especially when the multiple drones are deployed, communication among each drone and a ground control station (GCS) is essential for delivering control message. However, traditional routing algorithms take too long time to construct routing table (eg. proactive routing protocol) or require large...
Vehicular ad hoc network (VANET) is suffering from the frequent link breakage and low packet delivery rate, which challenges routing protocols. To address this issue, we propose a Geographic Opportunistic Routing protocol based on Link state and Forwarding quality inside nodes (LF-GOR). We first put forward a hybrid approach of filtering and prioritizing to determine a candidate nodes set of the sending...
This paper proposes KAR (Key-for-Any-Route), a new intra-domain resilient routing system in which edge-nodes set a route ID to select any existing route as an alternative to safely forward packets to their destination. In KAR routing system, a route is defined as the remainder of the division between a route ID and a set of switch IDs along the path(s) between a pair of nodes. KAR-enabled switches...
Mobile ad hoc networks (MANETs) are emerging as a practical technology for emergency response communication in the case a centralized infrastructure malfunctions or is not available. Using smartphones as communication devices, MANETs may be readily established among the civilian population of affected areas. Beneficiaries would be civilian first responders, which may form small collaborating groups...
With the ever-increasing emphasis on the importance of vertical integration for the fourth industrial revolution (Industrie 4.0), we contend that the largest potential lies in the replacement of single-purpose gateway-ing solutions with distributed gateway service bus (GSB) technologies. Within this paper, we primarily focus on the aspect of routing between variously grouped GSB components. We base...
In challenged networks, such as opportunistic networks or Delay Tolerant Networks (DTNs), due to frequent network partition an end-to-end connection between source and destination may not always be possible due to nodes move unpredictably with high speeds. For such type of networks, traditional routing protocols fails to transmit and also no guarantee on delivery of data to specified destination because...
Industrial Wireless Sensor-Actuator Networks (WSANs) enable Internet of Things (IoT) to be incorporated in industrial plants. The dynamics of industrial environments and stringent reliability requirements necessitate high degrees of fault tolerance. WirelessHART is an important industrial standard for WSANs that have seen world-wide deployments. WirelessHART employs graph routing to enhance network...
