Wireless sensor network supports reliable monitoring of the given network based upon the data transmitted from the sensors. However, the feasibility can be maintained only when the delivered data are fairly reliable without any damage. Since data error is not an uncommon event in wireless sensor networks, the validity of the decision making strongly depends upon the stableness of the data analysis...
With the arrival of big data era, data mining techniques have been widely used to build models for cyber security applications such as spam filtering, malware or virus detection, and intrusion detection. This project proposes a novel approach that uses randomness to improve robustness of data mining models used in cyber security applications against attacks that try to evade detection by adapting...
In this paper, we present AdaptSens: a reliable data collection and storage system for solar-powered sensor networks. Unlike battery-operated devices, solar-powered systems have a less predictable energy supply and their ability to harvest energy depends on past spending, thereby creating incentives for adaptive matching of energy supply and demand. Our storage system is novel in its layered architecture...
There are several surveillance and reconnaissance applications of sensor networks (such as military), which require timely and efficient detection of an event (i.e., enemy troops and vehicles). Moreover, the information gathered is then transferred reliably to a sink, located at a remote control station. Incorporation of multimedia data (e.g., image) certainly enhances the functionality and applicability...
ESRT protocol is a transport solution that seeks to achieve reliable event detection solution with minimum energy expenditure and congestion resolution. Depending on the current network state, it configures the reporting frequency rate f for the next time interval. Due to the dynamic properties of the networks, the adjustment always has a delay. A prediction-based ESRT (PBESRT) protocol is presented...
This paper presents FDF (false destination forwarding), a technique that can be adopted for multipath routing in wireless sensor networks to avoid the overhead caused by the maintenance of disjointed or partially disjointed routing paths. FDF changes the packet destination target as the packet itself proceeds along the path: this way, it does not require any change to the underlying geographic routing...
A Wireless Sensor Network (WSN) contains several sensor nodes with very limited sources such as a small microcontroller and a battery. These features usually result in difficulties in employing most of the conventional wireless network protocols (e.g., security protocols) unfavorably. Research on especially increasing reliability of the WSNs employed in health applications recently receives a remarkable...
The congestions in wireless sensor networks have two types: link congestion and node congestion. The primary method for congestion avoidance is to control sending rate, through the mechanism of distribution rate and cache notification. Multi path is the primary method for guaranteeing transmission reliability in wireless sensor networks. Aiming at the node congestion, MPCN-multi path based on cache...
The paper proposes Markov models for the reliability analysis of the wireless sensor networks. There are presented the theoretical aspects and some of the variables that are used in the domain of fault tolerant systems. There is also presented a comparison between systems using dedicated replacements and universal replacements for defective nodes. There has been conducted a study regarding the reliability...
This paper focuses on congestion control but while previous works considered scalar sensor nodes which only report events in the size of a few bytes, we are addressing congestion control for information-intensive flows such as video flows for surveillance applications in pervasive wireless multimedia sensor networks. The proposed framework that we describe in this paper tries to put several mechanisms...
Instant wireless sensor network (IWSN) is a type of WSN deployed for a class of special applications which have the common requirement on instantly responding for collecting and transmitting sensory data, e.g., volcanic eruption monitoring or nuclear leakage detection. In this paper, having a cluster-based WSN, we present a compensation-based reliable data delivery protocol (CRDD) to collect and transmit...

On light of the technology combination of WSN, MAS and RST, and its contribution to the framework of healthcare sensor decision network, this work further studies the multiplicity of intelligent agent based healthcare sensor decision network, and proposes the hierarchical...
In this work, we present a distributed framework for provision of reliability to visual data in wireless multimedia sensor networks (WMSNs). Individual sensor nodes cooperate, in a pair-wise fashion, to allocate processing resources within the network which are then used to partially decode the incoming data as it traverses the multi-hop network. We show that the proposed framework outperforms the...
There are two states in event-driven wireless sensor network, one is non-event state, and the other is event state. In non-event state, the network traffic is very small and the requirement for real-time performance of network is not strict. However, in event state the traffic is large, the critical information would be lost once the link quality goes bad without responding timely. This paper does...
To reduce the transmissions among sensor nodes and prolong the lifecycle of the wireless sensor network, a data fusion mechanism based on immune was put forward. The self-study and self-adaptation characters of artificial immune system were used to bring an immune fusion algorithm forward. In the algorithm, the immune anti-redundancy, immune selection and immune memory were used to ensure high reliability...
The advantage of a Wireless Sensor Network (WSN) compared to a centric approach is the distribution of sensing suites. However, in order for such a system of distributed resources to work in a reliable and effective way a smart cooperation between nodes is needed. In this paper we propose a middleware approach for a highly reliable data storage that helps to assure data availability despite the well...
Wireless distributed micro-sensor systems enable the reliable monitoring of a variety of environments for both civil and military applications. A major issue in the design of Wireless Sensor Networks is to develop strategies to make efficient use of its energy and to increase the reliability of data. In this paper, we address the problem of routing the data in an hostile environment. The proposed...
Wireless sensor networks (WSNs) play an important role in several application fields. They are composed by a dense deployment of small and low-power devices (called sensors) that cooperate together in order to perform some special tasks. These networks are often characterized by the spatial and temporal correlation of the sensor observations. Several works are investigating these correlations in order...
