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...
Vehicular Ad Hoc Network (VANET) is a subgroup of mobile ad hoc network (MANET). It is an emerging new technology to exchange information between vehicles to vehicles. VANETs are considered as one of the most noticeable technologies for improving the efficiency and safety of transportation systems. VANET mainly used to exchange traffic information between the vehicles and prevent accident. In VANETs...
This paper is concerned with a crucial problem of MANET which is congestion control (CongClt). CongClt can be described as a mechanism used to control congestion (Cong) and keep the traffic below the capacity of the network. Many approaches have been proposed to overcome CongClt in Ethernet as well as in MANET. Controlling the Cong in MANET is quite difficult due to its fundamental characteristics...
Wireless Body Area Networks (WBANs) consists of biosensors which are used for health monitoring and diagnostic purposes. Moreover, the biosensors are constrained to the issue such as link quality, delay and multihop energy consumption. In order to overcome these issue an Optimized Fuzzy based Swarm Routing (OFSR) is proposed for WBAN. In this technique, first selection of best node is done based on...
In MANET nodes are power constrained, for the reason that nodes has operated with limited battery energy or power. The nodes in network are not communicated with each other because of early depletion of mode energy. The nodes which are completely lost their energy in network are not possible to further communicate with other nodes without the replacement or charge the battery of node in dynamic network...
Most existing mobile ad hoc network (MANET) routing protocols use the minimum number of hops as a routing metric. These paths tend to contain long range links that may degrade both throughput and reliability. Higher throughput can be achieved by using short but effective links. The main problem with existing protocols is that they use only receiver signal strength indicator (RSSI) value to assess...
In vehicular communications, the current standards can be applied for safety-related message exchange but in the future world, other new applications like autonomous controlled vehicles require more reliability and capacity with small delay. Moreover, the harsh communication environment is one of the most difficult challenges. The line-of-sight (LOS) component of the signal in inter-vehicle connectivity...
Underwater sensor networks (USNs) has many characteristics different from terrestrial wireless sensor networks (WSNs), such as dynamic network topology, unreliable acoustic communication, which increases the difficulty in energy efficiency and reliability of data transmission, for traditional WSN protocols are not suitable for underwater acoustic sensor networks (UASNs). Vector based forwarding (VBF)...
Wireless sensor network (WSN) is a network of small, low power, resource constrained devices distributed in a large area. The principle focus of such network is to monitor some well-defined phenomenon in the sensor field. Availability of low power CMOS camera has offered wings to WSN applications. Broadening the range of applications from monitoring to multimedia surveillance. Multimedia transmission...
Advanced Metering Infrastructure (AMI) network is the capillary communication network for smart grid that does not only provide the data collection from each household but also delivers configuration requests from intelligent energy services. However, the smart grid network challenges like heterogeneity, large-scale, and distributed operation must be solved for reliable and stable smart grid services...
With the research and application of wireless sensor networks are widely used in the medical field. It is put forward higher requirements for its reliability, flexibility and high efficiency. Changeable and unpredictable characteristics of the medical field environment are major factors that lead to the reliability decline in medical wireless sensor network. Finding a reliable path is an effective...
Wireless networks are becoming popular because of their ease of access and connectivity, especially the Ad hoc network, which can be setup in a minute and supports mobility. The ad hoc network is at very early stage, but evolving fast. Mobile Ad hoc Network (MANET) is a kind of ad hoc network consists of mobile nodes connected through wireless technology. It is open, decentralized, low powered and...
A mobile ad-hoc network is a wireless network such that nodes are move dynamically in network. In OSI network layer there is lot of attack but introduce only collaborative black hole and worm hole attack. A group of black hole node easily employed against routing in mobile ad-hock networks called collaborative black hole attack. When two malicious node is create a tunnel is called worm hole attack...
In this paper, we presents a routing protocol called Enhanced Hybrid Traffic-Aware Routing (EHTAR) to cope with the dynamics of Vehicular Ad Hoc Network (VANET) in urban environment. In EHTAR, an elected functional node called Junc-Tracker located at each junction is used to explore the real-time vehicular and network traffic information in each road segment. This information enables each Junc-Tracker...
Vector based forwarding (VBF) routing protocol is a location-based energy efficient routing protocol designed for underwater acoustic sensor networks (UASNs). In this paper a VBF-improved routing protocol is proposed, which uses not only the information of location but also the residual energy and the number of retransmission in last cycle to make decision whether to make data forwarding. According...
In order to increase the network latency and resolve the security bottlenecks induced by the camouflaged malicious nodes in Wireless Sensor Networks, the residual energy and trust values are used to form a secured clustering, the network lifetime is increased by using the backup nodes in order to distribute the load among the secured clusters and reliable multipath node disjoint route discovery algorithm...
Vehicular Ad Hoc Network (VANET) is a subclass of Mobile Ad Hoc Network (MANET). QoS routing protocols are fundamental part of VANETs that aim to provide services with guaranteed quality. Existing routing protocols of MANET can be applied to VANETs as well but they do not perform well under the dynamic conditions of VANETs such as, fast moving nodes and frequent disconnections in the network. In this...
Current system administrators are missing intrusion alerts hidden by large numbers of false positives. We propose an intrusion detection tool that effectively uses select data to provide a picture of "network health". Our hypothesis is that by utilizing the data available at the node and network levels we can create a synoptic picture of the network providing indications of many intrusions...
Internet of Things (IoT) is becoming a reality and new and advanced applications are expected to emerge. For applications with reliability needs to work well in IoT environments, robust data transportation is required. Approaches like TCP are known for not being adequate in sensor network environments, while UDP has been included in the 6LoWPAN stack allowing low-power and limited processing devices...
