In the area of biomedical engineering, digital-microfluidic biochips (DMFBs) have received considerable attention, because of their capability of providing an efficient and reliable platform for conducting point-of-care clinical diagnostics. System reliability, in turn, mandates error-recoverability while implementing biochemical assays on-chip for medical applications. Unfortunately, the technology...
In Wireless Sensor Network, sensor nodes are low powered and small devices mainly deployed in critical regions. Due to their energy constraint issues, many routing algorithms have been developed for efficient forwarding of data for minimizing energy consumption. Considering the static sink, nodes near the sink will have more load for routing data, therefore sink has been made as mobile. Now the sink...
In Data center network, with the rapid development of network applications, how to balance the network load has become the focus of everyone's attention. It is required to fully utilize the resources such as bandwidth to provide high bandwidth for various cloud computing service. In this paper, we propose a dynamic load balancing routing mechanism based on disturbance under SDN. The proposed scheme...
The rapid development in communication approach has brought out new mode of communication. Among the recent developments, adhoc network has emerged as new mode of data communication.

The approach suggested, results...
Wireless sensor networks deployment and operation are most likely to take place under hazardous conditions. One extreme scenario is the deployment of a wireless sensor network in a mountainous and forested region in which a fire has ignited, for the purpose of localizing and /or tracking, in real time, its spread. Some methods developed in this paper are expected to provide superior performances under...
Rapidly falling costs of photovoltaic generation and electrical energy storage devices are prompting the proliferation of self-contained electricity systems in homes and buildings, that can be called homegrid, and several of these homegrids form a microgrid. The homegrid consists of local generation, storage and utilization devices, which may or may not interconnect to a central utility system. A...
In recent past, researchers have shown a lot of interest in Under Water Sensor Networks (UWSNs) because of its application in wide range of domains. UWSN, actually a sub body of Wireless Sensor Networks (WSN), facilitate with radio communication with high-precision of information to a sink node from any of the source node. The Role of any-casting is of significant importance in the context of routing...
We present our thoughts on the design of a novel hybrid system for detecting anomalous traffic in large-scale, policy-rich data networks. A key innovation in our approach is the combination of static configuration analysis and dynamic traffic analytics. More specifically, we will first develop abstractions and mathematical models to formally model the network and security configurations to statically...

In this scheme, a crop field is equipped with different types of sensor nodes with limited power source, placed randomly for sensing various...
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...
SpaceWire is a full-duplex, point-to-point, high-speed serial data transfer standard which is intended for use in further on-board spacecraft, space missions and applications. However, space environment is harsh and complex which requires a communication network with high reliability. It is inevitable that SpaceWire network link fault or SpaceWire equipment damage is able to change the SpaceWire network...
BGP measurement is important for monitoring and understanding the Internet anomalies. Most of the previous works on BGP measurement rely on aggregated statistics from BGP monitors, e.g., total updates. However, BGP events may have quite limited visibility. Therefore, merely investigating aggregated data may lead to misunderstanding Internet instability, e.g., overestimating the impact of monitor-local...

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...
Security in wireless sensor networks is critical due to its way of open communication. In this paper we have provided a solution to detect malicious nodes which perform radio transmission power control attack and sinkhole attack in wireless sensor networks. In the proposed approach, data transmission is divided into multiple rounds of equal time duration. Each node chooses the parent node in the beginning...
Wireless sensor networks (WSNs) are widely used nowadays in various domains. In general, the applications in which the WSN is deployed need that this network presents a minimal degree of reliability, effectiveness and robustness. However, the specificity of the nodes deployed in this type of networks makes them prone to failures. In this paper, we discuss the recovery from simultaneous failures for...
Moving Target Defense (MTD) is based on the notion of controlling change across various system attributes with the objective of increasing uncertainty and complexity for attackers; the promise of MTD is that this increased uncertainty and complexity will increase the costs of attack efforts and thus prevent or limit network intrusions. As MTD increases complexity of the system for the attacker, 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...
Software-defined networking (SDN) supports flexibly routing and switching by splitting the control plane and data plane in network devices. However, the security resource utilization now in SDN is inefficient, especially in the process of routing path construction. In this paper, we present a novel model for SDN controller to construct secure routing paths based on Network Security Virtualization...
In corona-based Wireless Sensor Networks (WSNs), nodes that are positioned in coronas near the sink drain their energy faster than others as they are burdened with relaying traffic come from distant coronas forming energy holes in the network. This situation shows significant effects on the network efficiency in terms of lifetime and energy consumption. The network may stop operation prematurely even...
In underwater, the sensor nodes deployed randomly will form the network and gather data.
