- Wireless soil sensors to help farmers
- A research team at Iowa State University ISU is developing wireless soil sensors to improve farming while minimizing environmental impacts. ISU says that 'the prototype sensors are designed to collect and send data about soil moisture -- and eventually soil temperature and nutrient content -- while working completely underground.' According...

- Light Trails: A Sub-Wavelength Solution for Optical Networking
- All-optical networks are able to transport data from source to destination entirely in the optical domain. This is a departure from current optical networks that rely on Optical-Electrical-Optical OEO conversion at each intermediate connection node to route data properly. The opacity inherent in traditional networks is costly in terms of...

- On Multicasting in Wavelength-Routing Mesh Networks
- This paper considers multicasting on wavelength-routing mesh optical networks. Although multicasting has been studied extensively in different network environments, multicasting in this environment is different, and more involved. The paper discusses the challenges of multicast support in optical wavelength routing networks, and reports on the advances made so far in...

- Speeding Up Multi-Relational Data Mining
- This paper presents a general approach to speeding up a family of multi-relational data mining algorithms that construct and use selection graphs to obtain the information needed for building predictive models (e.g., decision tree classifiers) from relational database. Preliminary results of the experiments suggest that the proposed method can yield...

- A Cost-Sensitive Model for Preemptive Intrusion Response Systems
- The proliferation of complex and fast-spreading intrusions not only requires advances in intrusion detection mechanisms but also demands development of sophisticated and automated intrusion response systems. This paper presents a novel cost-sensitive model for intrusion response that incorporates preemptive deployment of the response actions. Specifically, the technique relies on comparing...

- Feature Selection in Intrusion Detection System Over Mobile Ad-Hoc Network
- As Mobile Ad-hoc Network MANET has become a very important technology the security problem, especially, intrusion detection technique research has attracted many people's effort. MANET is more vulnerable than wired network and suffers intrusion like wired network. This paper investigated some intrusion detection techniques using machine learning and proposed a...

- Victim-Assisted Mitigation Technique for TCP-Based Reflector DDoS Attacks
- This paper develops the concept of victim-assistance for Denial of Service DoS mitigation. The proposed concept is utilized within a simple, yet effective scheme designed for mitigating TCP-based reflector DoS attacks. The proposed scheme, called SYN number based filtering SNF, takes into account the TCP's connection establishment behavior and the...

- A Service-Oriented Architecture for Electric Power Transmission System Asset Management
- In electric power transmission systems, the assets include transmission lines, transformers, power plants and support structures. Maintaining these assets to reliably deliver electric energy at low prices is critical for a nation's growth and development. Towards this end, the authors describe a novel service-oriented architecture for sensing, information integration, risk...

- Biodegradable plastics made from corn
- Biodegradable plastics have already been created by using proteins from plants such as corn or soy. But they were not strong enough to be used by the industry. Now, researchers at Iowa State University have found a way to reinforce these biorenewable plastics. They are using high-powered ultrasonics to reinforce...

- QoS-Based Service Composition
- QoS has been one of the major challenges in Web Services area. Though negotiated in the contract, service quality usually can not be guaranteed by providers. Therefore, the service composer is obligated to detect real quality status of component services. Local monitoring can not fulfill this task. This paper proposes...
