The devices surrounding us become smarter and can autonomously form a network without requiring our intervention. However, our needs can be even better accommodated when the networked devices cooperate and complement each other's capabilities. One of the initial steps towards achieving a cooperative platform of smart devices is the discovery of resources and capabilities within the network. Today's operational service discovery protocols carry simple text-based uniform resource identifiers that are not expressive enough. Machines cannot comprehend the meaning of a new service that is not in their knowledge base. In addition to being more expressive, service discovery protocols must compensate the diversity to improve cooperation between the devices that use different application protocols and operate on different communication interfaces. In this paper, we propose the Smart Discovery Protocol (SDP) which outperforms the operational service discovery protocols with three main features: (1) more expressive semantic representation of the services, (2) operating in the network layer to deal with diversity, and (3) unifying existing service discovery protocols. SDP represents services with ontologies as some recently proposed semantic service discovery protocols. It further enhances the success of semantic representations by creating a unified platform that can carry legacy discovery services. In this respect, the novelties of SDP are as follows: firstly, it operates in the network layer and consequently abstracts both the application layer and communication interfaces. Secondly, SDP unifies the legacy service discovery protocols by integrating their simple text-based service representations in one message. The underlying transport mechanism of SDP is designed as an add-on to the Neighbor Discovery Protocol (NDP) of the IPv6 standard. The metadata is carried in the payload of ICMPv6 packets. Simple text-based representations of other service discovery protocols are embedded in type-length-value options of NDP. Authenticity of the devices is ensured by the IPv6 Secure Neighbor Discovery protocol. Unlike previous semantic approaches on service discovery, we have implemented our protocol on real hardware. The results demonstrate the feasibility of carrying semantic representations of the services and integration of other service discovery protocols.

Explainable Security in SDN-Based IoT Networks Sarica, Alper Kaan; Angın, Pelin (2020-12-01) The significant advances in wireless networks in the past decade have made a variety of Internet of Things (IoT) use cases possible, greatly facilitating many operations in our daily lives. IoT is only expected to grow with 5G and beyond networks, which will primarily rely on software-defined networking (SDN) and network functions virtualization for achieving the promised quality of service. The prevalence of IoT and the large attack surface that it has created calls for SDN-based intelligent security solut...
Performance evaluation of flexray networks for in-vehicle communication Demirci, Ali; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2009) The increasing use of electronic components in today’s automobiles demands more powerful in-vehicle network communication protocols. FlexRay protocol, which is expected be the de-facto standard in the near future, is a deterministic, fault tolerant and fast protocol designed for in vehicle communication. In the near future, safety critical X-by-Wire applications will be available in the automobiles and FlexRay networks can be used to provide communication for the Electronic Control Units (ECUs) that perform...
Wireless Body Area Network Studies for Telemedicine Applications Using IEEE 802.15.6 Standard Ozderya, Hasan Yavuz; ERDÖL, HAKAN; KAYIKÇIOĞLU, TEMEL; Yılmaz, Ali Özgür; KAYA, İSMAİL (2017-03-18) Wireless communication is becoming a part of our life at every step. But widespread use in medical applications is yet to come. We are developing a wireless communication system based on 802.15.6 MAC and 802.15.4 PHY for use in transmitting ECG data from a remote patient monitoring device which is used for home based telemedicine applications. The paper concentrates on explaining the stack program development phases of the standard IEEE 802.15.6 and its flexible access features. It is believed that the subj...
Training Methodology for a Multiplication Free Implementable Operator Based Neural Networks Yıldız, Ozan; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2017) Technological advances opened new possibilities for computing environments including smart phones, smart appliances, and drones. Engineers try to make these devices smart, self-sustaining through usage of machine learning techniques. However, most of the mobile environments have limited resources like memory, computing power and battery, and consequently traditional machine learning algorithms which require relatively high resources might not be suitable for them. Therefore, efficient versions of traditiona...
Real-time intrusion detection and prevention system for SDN-based IoT networks Sarıça, Alper Kaan; Angın, Pelin; Department of Computer Engineering (2021-9) The significant advances in wireless networks with the 5G networks have made possible a variety of new IoT use cases. 5G and beyond networks will significantly rely on network virtualization technologies such as SDN and NFV. The prevalence of IoT and the large attack surface it has created calls for SDN-based intelligent security solutions that achieve real-time, automated intrusion detection and mitigation.
