Mobile Ad hoc Network has a wide range of applications in military and civilian domains. It is generally assumed that the nodes are trustworthy and cooperative in routing protocols of MANETs viz. AODV, DSR etc. This assumption makes wireless ad hoc network more prone to interception and manipulation which further open possibilities of various types of Denial of Service (DoS) attacks. In order to mitigate...
In this paper, a health care system is described for rural areas considering a small village using hybrid network i.e. which operates both in ADHOC and cellular region. In this system, a small village is considered in which sensors are attached to people, the whole area is divided into clusters. The sensors considered for this system can operate in both ADHOC and GSM region. In each cluster, a sensor...
The successful deployment of low-power wireless sensor networks (WSNs) in real application environments is a much broader exercise than just the simple instrumentation of the intended monitoring site. Many problems, from node malfunctions to connectivity issues, may arise during commissioning of these networks. These need to be corrected on the spot, often within limited time, to avoid undesired delays...
Underwater Wireless Sensor Network (UWSN) is newly emerged and developed branch of Wireless sensor technology. In UWSN small sensor nodes with limited battery and limited memory are deployed in underwater environment. Due to multiple differences from terrestrial Wireless Sensor Networks (WSN), radio waves cannot be used in underwater communication. Acoustic channels are used for communication in sea...
In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
In the last few years Ambient Assisted Living (AAL) has come up a long way with numerous innovative ideas to cater to the growing elderly population of the society. With a perfect combination of tools and technology leading to ubiquitous or pervasive computing, data can be sensed, and transmitted from patients at home to healthcare professionals for quick monitoring and taking necessary actions, if...
Recent research demonstrated that software defined networking (SDN) can be leveraged to enable moving target defense (MTD) to mitigate distributed denial of service (DDoS) attacks. The network states are continuously changed in MTD by effectively collecting information from the network and enforcing certain security measures on the fly in order to deceive the attackers. Being motivated from the success...
Recent advances in environmental sources harvesting technologies is a promising solution to provide sustainable energy sources for wireless sensor networks (WSN). Renewable energy sources such as solar, thermal and electromagnetic waves constitute viable alternatives to maximize the network lifetime. Therefore, networking software awareness and adaptability to energy availability conditions should...
With energy being the most valuable resource in self-powered Wireless Sensor Networks (WSNs), the ability to monitor individual node power levels and route accordingly becomes crucial to ensure longevity of a network's lifetime. In this paper, an Energy Conscious Opportunistic Routing Protocol (ECORP) is demonstrated, which allows energy conservation measures to be implemented without hindering the...
The Border Gateway Protocol (BGP) plays a critical role in the Internet providing connectivity to hosts across the world. Unfortunately, due to its limited security, attackers can hijack traffic by generating invalid routes. Some detection systems for route hijacking have been presented, but they require non-public information, high resources, or can easily be circumvented by attackers. We propose...
Wireless Sensor Network (WSN) is a system used to conduct a remote monitoring in a wide monitoring area. It has a sensor node — a sampling point — which communicate each other to passing their data to central node for recapitulation or transmit it to data center. Because of that, communication system is a crucial thing for WSN. However, WSN may be deployed in a environment that far from ideal condition...
Given the fact that LEACH protocol didn't take the residual energy of nodes into account when choosing the cluster heads, which may result in the node with rather low energy to be chosen as a cluster head. Thus, it will cause the cluster created by this low-energy node to be dead at an early stage, which wastes the whole network's resource. Here in this paper, we introduced an energy factor when choosing...
Often times there is a need to do remote monitoring. The remote sites may be located far away; thus, traditional connectivity, such as fiber, is not possible. This paper proposes to use unmanned aerial vehicles (UAVs) to provide connectivity to ground sensor clusters on a suburban industrial area. Very small, commercial scale UAVs can be used to monitor a bunch of ground sensor nodes without the dependency...
Smart home is a residence or dwelling connecting communication networks with electrical equipment for menegndalikan and monitor remotely. Smart home in the market today have a fairly expensive and communication between devices using a certain standard so it is not easy if you want to do further development. This research aims to use technology based on IP (Internet Protocol) to allow users to monitor...
We address the problem of identifying and isolating misbehaving nodes that refuse to forward packets in multi-hop ad hoc networks. We develop a comprehensive system called Audit-based Misbehavior Detection (AMD) that effectively and efficiently isolates both continuous and selective packet droppers. The AMD system integrates reputation management, trustworthy route discovery, and identification of...
Automated metering infrastructure is employed widely in scientific fields as well as in industrial and commercial areas due to the development of wireless sensor network (WSN) technology. WSNs provide important features such as wireless multi-hop communication and they are easy to install everywhere; thus, extending the lifetime of WSNs is highly desirable. All WSN nodes consume a limited amount of...
In this work, we propose an adaptive congestion control and avoidance mechanism as an enhancement to our earlier proposed QoS-aware routing protocol. We utilize Ant Colony Optimization (ACO) algorithms for adaptive multipath routing and use the monitoring feature of the Simple Network Management Protocol (SNMP) for QoS computation. So, merging these two methodologies we propose a powerful adaptive...
Reducing the power consumption of the internet backbone networks is one of the major challenges in computer networks because of high energy cost and environmental issues. SDN is the promising technology that enables fine grain control of network traffic. In this paper, we propose a novel traffic management and routing framework, called SDGTE (Software Defined Green Traffic Engineering), that minimizes...
After Internet routing was shown in a number of classic measurement papers to result in paths that are sub-optimal with respect to a number of metrics, routing overlays were proposed as a method for improving performance, without the need to re-engineer the underlying network. In this paper, we present SMART, a self-healing, self-optimizing and highly scalable routing overlay, which has a number of...
In recent years, due to the technological development of various kinds of drones, also known as unmanned aerial vehicles (UAVs), drones have emerged as an effective solution for a wide area of applications. In such applications, employing multiple drones promises a better way to carry out a given mission than employing a single drone. To utilize multiple drones, all drones should establish a network...
