[more] © 2017 EAI. Today there are several health care related problems such as dementia and cancer with no possible cure. Hence there is considerable interest in the medical sectors and constant encouragement from the governments to make use of the latest technological advancements for supporting such patients. Software Defined Networking(SDN) is a promising technological advancement in the networking world. In this paper we propose techniques for making use of the SDN, Wireless LAN and wearable devices for secure monitoring of the patients with wandering behaviour in hospital environments. Our model makes use of the global network knowledge available at the SDN controller to deal with the attacks in WLAN and provide priority for real time location monitoring of the patients. We will also present the prototype implementation of our model using ONOS SDN controller and OpenFlow Access Points.

[more] © 2017 IFIP. In this paper we proposed policy based security architecture for securing the communication in multiple Autonomous System (AS) domains with Software Defined Networks (SDN). We will present a high level overview of the architecture and detail discussion on some of the important components for securing the communication in multiple AS domains. A key component of the security architecture is the specification of security policies that are to be enforced on the SDN communications whether they are intra or inter-domain. We will present example scenarios to demonstrate the operation of the security architecture to enable end-to-end secure communication within a single AS domain and for multiple AS domains. We have justified the model using ONOS controller.

[more] © 2016 ACM. Software Defined Network(SDN) is a promising technological advancement in the networking world. It is still evolving and security is a major concern for SDN. In this paper we proposed policy based security architecture for securing the SDN domains. Our architecture enables the administrator to enforce different types of policies such as based on the devices, users, location and path for securing the communication in SDN domain. Our architecture is developed as an application that can be run on any of the SDN Controllers. We have implemented our architecture using the POX Controller and Raspberry Pi 2 switches. We will present different case scenarios to demonstrate fine granular security policy enforcement with our architecture.

[more] During the path establishment, states of switching elements in the switch network may need rearrangement. C.-T. Lea et. al [1] has first mentioned about the rearrangement behavior of the switching networks. He has analyzed the frequency of its occurrence using stochastic method. It is notable that rearrangement behavior of switching network includes rearrangement of connections and rearrangement of switching elements. Optimization of rearrangement cost of switching network can save both power and time, which in turn can increase the switching speed. This paper determines the rearrangement cost of strictly non-blocking Vertically Stacked Optical Banyan networks in terms of switching elements. We believe that our result will be helpful in designing, implementing and analyzing different algorithms of the networks. © 2013 IEEE.

[more] This paper represents the novel numerical simulation and hardware simulation of the proposed ¿- shape microstrip Antenna. The proposed antenna can cover mobile Worldwide Interoperability for Microwave Access (WiMAX) bands as well as Wireless-Fidelity (Wi-Fi) bands. This antenna also operates in the Industrial, Scientific and Medical (ISM) band at 2.45 GHz for biomedical applications. Our proposed ¿- shape microstrip antenna covers full bandwidth of 2.3 GHz mobile WiMAX (IEEE802.16e-2005 frequency spectrum 2.3-2.4 GHz), 2.4 GHz Wi-Fi (2.4-2.5 GHz) operation with sufficient SWR & gain. The proposed antenna provides excellent SWR of 1.045 and a total gain of 15.92 dBi at 2.45GHz. The overall dimension of the proposed antenna is 51 × 35 × 35 mm. The simulation results are obtained by antenna simulator (4nec2X) and in the antenna laboratory. © 2013 IEEE.
