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...
A key aspect of realizing the future smart grid communication solution is a balanced approach between the network performance and the network security during the network deployment. A high security communication flow path is not useful when the network path cannot support capacity and reachability requirements. The deployment phase in communication network can facilitate an optimal network path by...
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...
The aim of this research is to enhance the performance of a traditional Enhanced Interior Gateway Routing Protocol (EIGRP) network by adding some features of the Software Defined Networking (SDN) in a modified approach to improve some network's performance metrics like link congestion and packet loss. The improvement of those metrics leads to an improvement in the total throughput of the network....
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...
Multicasting, which is a one-to-many communication, is motivated by the increasing importance of real-time and multimedia applications with different QoS requirements. This paper presented a non-uniform distributed hash function for wireless ad hoc networks. This function allocates a unique interval to the receiver nodes based on the path weight and the random speed of nodes. This allocation leads...
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...
In recent years the usage of Wireless Sensor Networks (WSNs) for industrial applications (robotics, process automation, monitoring and control of critical systems) is gaining momentum. The dependability is one of the main pillars for the requirements in these application areas and can be defined in terms of reliability and maintainability. The definition of reliability is dependent on the application...
Underwater acoustic sensor networks (UW-ASNs) are deployed in the water to gather the information of interest. They can gather information regarding temperature, pressure, pollution and environment of the ocean. There is requirement of energy efficient routing protocols to convey information to the sink. Energy efficient routing protocols used in terrestrial networks are not suitable for underwater...
