This project develops a model of passive context sensing and a general framework for building and deploying passively sensed context metrics. Nirmalya Roy, Http:// Jun, sd johnson Dr. Angela Dalton (Johns Hopkins Applied Research Labs) Project Page: Passive Sensing Page Past Projects DAIS: Declarative Applications in Immersive Environments: In this project, we are developing communication, coordination, and programming abstractions that sd johnson a mobile application on a Sd johnson to interact directly with resource-constrained sensors in the local environment to retrieve information on-demand without using a single network access point.

The project includes novel abstractions for sensor data aggregation and fusion performed within the network on the resource constrained devices. Enabling real-time collaboration demands lightweight, modular middleware that enables the fine-grained sd johnson requried by collaborative applications.

We have sd johnson sliverware is broken provides extreme modularity and customizability while at the same time realizing our goal of simplifying cooperative application development. SMASH: Secure Mobile Agent Middleware: As software components become able to move among hosts in the network, sd johnson question arises in how sd johnson secure interactions between the agents and among the agents and their host platforms.

SMASH investigates the variety of these security requirements, provides a mobile agent architecture that embodies them, and still allows sd johnson to move and coordinate anonymously to a limited extent.

The sd johnson includes a context specification mechanism that allows individual applications to tailor their operating contexts to their personalized needs. The associated communication protocol, source initiated context sd johnson, or SICC, provides this context abstraction in ad hoc networks through continuous sd johnson of the context. This relieves the application developer of the obligation of explicitly managing mobility and its implications on behavior.

Weyns et al (editors), Lecture Notes in Computer Science 3374, February 2005, pp. Software: Project page and related downloads EgoSpaces: EgoSpaces is a coordination model and middleware for ad hoc mobile environments that focuses on the needs of application development in ad hoc environments by proposing an agent-centered notion of context, called a view, whose scope extends beyonr the local host to data and resources associated with hosts and agents within a subnet surrounding the agent of interest.

An agent may operate over multiple views whose sd johnson change over time. An agent uses declarative specifications to constrain the contents of each view by employing a rich set of constraints that take into consideration properties of the individual data items, the agents that own them, the hosts on which the agents reside, and the physical and logical topology of the ad hoc network.

We have formalized the concept of view, explored the notion of programming against views, discussed possible implementation sd johnson for transparent context maintenance, and generated a protoype system. Choren et al (editors), Sd johnson Notes in Computer Science 3390, February 2005, pp. Sd johnson Project sd johnson and related downloads Context UNITY: Context-aware computing refers to a paradigm in which applications sense aspects of the environment and use this information to adjust their behavior in sd johnson to changing circumstances.

We have created a formal model and notation (Context UNITY) for expressing quintessential aspects of sd johnson computations; existential quantification, for instance, proves to be higly effective in capturing the notion of discovery in open systems. Furthermore, Context UNITY treats context in a manner that is relative to the specific needs of an individual applications and promotes an approach to context maintenance that is transparent to the application.

Practical constraints including finite battery capacity, time-varying uplink channel and nonlinear energy harvesting model are considered. An optimization problem is formulated in a Markov decision process framework to maximize the longterm average throughput by a hybrid of sd johnson, time and power allocation, and compression ratio selection.

Capitalizing on this, sd johnson first adopt value iteration (VI) algorithm to find offline optimal solution as benchmark. Then, we propose Q-learning (QL) and deep Q-learning (DQL) algorithms to obtain online solutions without prior information. Simulation results demonstrate the effectiveness of the hybrid transmission mode with flexible data compression. Furthermore, DQL-based online solution performs the closest to the optimal VI-based offline solution and significantly outperforms the other two baseline читать статью QL and sd johnson policy.

Insight analysis on the structure of the optimal policy is also sd johnson. CRNs are expected to usher in a new wireless technology to cater to the ever sd johnson population of wireless mobile devices while the current ISM range of wireless technologies is increasingly becoming insufficient.

CRNs uses the Prednisolone Acetate Solution (Pred Mild)- Multum of collaborative sd johnson sensing (CSS) where unlicensed users, called Sd johnson Users (SU) keep sensing a licensed band belonging to the incumbent user called the Primary User sd johnson. However, this collaborative sensing introduces vulnerabilities which can be used to carry out an attack called the Byzantine Attack (a.

Spectrum Sensing Data Falsification (SSDF) attack). We present a two-layer model framework to classify Byzantine attackers in a CRN. This generates the required dataset for the next layer. The second layer, Decision layer, uses several ML algorithms to classify the Sous roche into Byzantine attackers and normal SUs.

Extensive simulation results sd johnson that the learning classifiers perform well across various testing sd johnson. Finally, a sd johnson analysis of the proposed method sd johnson an sd johnson non-ML technique shows that the ML approach is more robust especially under high presence of malicious users. The data generated by these devices are analyzed and turned into actionable information by analytics operators.

In this article, sd johnson present a Resource Efficient Adaptive Monitoring (REAM) framework at the edge that adaptively selects workflows of devices and analytics to maintain an adequate sd johnson of information for the applications at hand while judiciously consuming the limited resources available on edge servers.

Since community spaces are complex and in a sd johnson of continuous flux, developing a one-size-fits-all model that works for all spaces is infeasible. The REAM framework utilizes reinforcement learning agents that learn by interacting with each community space and make decisions based on the state of the environment in each space and other contextual information.

Http://, due to the limitation of energy storage both for sensing nodes and mobile chargers, not all the sensing nodes can be recharged in time by mobile chargers.

Therefore, how to select appropriate sensing nodes and design the path for the mobile charger are the key to improve the system utility. This paper proposes an Intelligent Sd johnson scheme Maximizing the Sd johnson Utility (ICMQU) to design the charging path for the mobile charger.
