Named Data Networking for Software Defined Vehicular Networks
Ahmed, Syed Hassan,Bouk, Safdar Hussain,Dongkyun Kim,Rawat, Danda B.,Houbing Song Institute of Electrical and Electronics Engineers 2017 IEEE communications magazine Vol.55 No.8
<P>Named data networking and software defined networking share mutual courage in changing legacy networking architectures. In the case of NDN, IP-based communication has been tackled by naming the data or content itself, while SDN proposes to decouple the control and data planes to make various services manageable without physical interference with switches and routers. Both NDN and SDN also support communication via heterogeneous interfaces and have been recently investigated for vehicular networks. Naive VNs are based on the IP-based legacy, which is prone to several issues due to the dynamic network topology among other factors. In this article, we first see both SDN and NDN enabled VNs from a bird's eye view, and for the very first time, we present an architecture that combines SDN functionalities within VNs to retrieve the required content using NDN. Moreover, we discuss a number of current research challenges and provide a precise roadmap that can be considered for the research community to jointly address such challenges.</P>
Named data networking-based smart home
Syed Hassan Ahmed,김동균 한국통신학회 2016 ICT Express Vol.2 No.3
Named data networking (NDN) treats content/data as a “first class citizen” of the network by giving it a “name”. This content “name” is used to retrieve any information, unlike in device-centric networks (i.e., the current Internet), which depend on physical IP addresses. Meanwhile, the smart home concept has been gaining attention in academia and industries; various low-cost embedded devices are considered that can sense, process, store, and communicate data autonomously. In this paper, we study NDN in the context of smart-home communications, discuss the preliminary evaluations, and describe the future challenges of applying NDN in smart-home applications.
DIFS: Distributed Interest Forwarder Selection in Vehicular Named Data Networks
Ahmed, Syed Hassan,Bouk, Safdar Hussain,Yaqub, Muhammad Azfar,Kim, Dongkyun,Song, Houbing IEEE 2018 IEEE transactions on intelligent transportation sy Vol.19 No.9
<P>In this paper, we propose a distributed interest forwarder selection (DIFS) scheme that mitigates the interest broadcast storm in vehicular named data networks. In DIFS, a vehicle sends an interest packet piggybacking its location, distance to the neighbors, and speed. In this case, the immediate neighbors do not have the requested content and rank themselves to be an eligible interest forwarder by using multiple attributes. Additionally, every intermediate vehicle uses a digital map to be selected as forwarders in both (forward and backward) directions of the consumer. Simulations show that DIFS satisfies more interest packets with less delay as compared with the recent forwarding solutions.</P>
RUFS: RobUst Forwarder Selection in Vehicular Content-Centric Networks
Ahmed, Syed Hassan,Bouk, Safdar Hussain,Dongkyun Kim IEEE 2015 IEEE communications letters Vol.19 No.9
<P>Vehicular Content-Centric Network (VCCN) has emerged as a future network technology for vehicular networks, where the focus of communication is shifted from the host to information centric. However, VCCN faces several challenges, including interest/data packet(s) flooding, provider/consumer mobility, and so on. In this letter, we propose a scheme named RobUst Forwarder Selection (RUFS) to mitigate the interest broadcast storm. In RUFS, each vehicle shares its satisfied interest(s) statistics with neighbors. All neighbors store this information in their Neighbors Satisfied List (NSL), which helps to select the potential interest forwarder. Simulation results show that RUFS outperforms the recently proposed NAIF, DR based and basic interest forwarding in VCCN.</P>
CODIE: Controlled Data and Interest Evaluation in Vehicular Named Data Networks
Ahmed, Syed Hassan,Bouk, Safdar Hussain,Yaqub, Muhammad Azfar,Kim, Dongkyun,Song, Houbing,Lloret, Jaime IEEE 2016 IEEE Transactions on Vehicular Technology VT Vol.65 No.6
<P>Recently, named data networking (NDN) has been proposed as a promising architecture for future Internet technologies. NDN is an extension to the content-centric network (CCN) and is expected to support various applications in vehicular communications [ vehicular NDN (VNDN)]. VNDN basically relies on naming the content rather than using end-to-end device names. In VNDN, a vehicle broadcasts an 'Interest' packet for the required 'content,' regardless of end-to-end connectivity with servers or other vehicles and known as a 'consumer.' In response, a vehicle with the content replies to the Interest packet with a 'Data' packet and named as a 'provider.' However, the simple VNDN architecture faces several challenges such as consumer/provider mobility and Interest/Data packet(s) forwarding. In VNDN, for the most part, the Data packet is sent along the reverse path of the related Interest packet. However, there is no extensive simulated reference available in the literature to support this argument. In this paper, therefore, we first analyze the propagation behavior of Interest and Data packets in the vehicular ad hoc network (VANET) environment through extensive simulations. Second, we propose the 'CODIE' scheme to control the Data flooding/broadcast storm in the naive VNDN. The main idea is to allow the consumer vehicle to start hop counter in Interest packet. Upon receiving this Interest by any potential provider, a data dissemination limit (DDL) value stores the number of hops and a data packet needs to travel back. Simulation results show that CODIE forwards fewer copies of data packets processed (CDPP) while achieving similar interest satisfaction rate (ISR), as compared with the naive VNDN. In addition, we also found that CODIE also minimizes the overall interest satisfaction delay (ISD), respectively.</P>

Constructed upon Knowledge Management (KM) processes, the current study aims to investigate the interrelationship between Knowledge Sharing (KS) attitude among the faculty members and KM processes in higher education institutes (HEIs) in Pakistan along with the intervening role of subjective norms between KM processes and KS attitude. This research incorporated the theory of Planned Behavior (TPB) and the theory of Reasoned Action (TRA) to conceptualize the KS behavior by using a sample frame of 302 academic and administrative staff from research-based HEIs in Quetta, Pakistan. A questionnaire-based survey was conducted on permanent faculty members from different universities of Quetta, Pakistan. The finding of the study shows a positive attitude among the researchers. The study empirically examined the interface between KM processes and KS attitude and higher education performance while providing valuable insights into the prevailing literature by investigating the mediating role of subject norms. The impact of subjective norms on KS attitude and KM process indicates the importance and basic determinant in organizational premises and improvement of skills of faculty management in HEIs. The partial mediation also reveals the importance of subjective norms in the development of faculty members’ KM and KS attitude process.
Smart Health: A Novel Paradigm to Control the Chickungunya Virus
Rani, Shalli,Ahmed, Syed Hassan,Shah, Sayed Chhattan IEEE 2019 IEEE Internet of things journal Vol.6 No.2
<P>Chikungunya is a mosquito instinctive disease that spreads hurriedly in various parts of the country. For the awareness and prevention measure of this disease a new paradigm in Smart Health (S-Health) required to be devised. The auspicious prospective of evolving Internet of Things (IoT) technologies for interconnected heterogeneous devices and objects has played a vital role in the next generation health care systems for eminent patient care to protect the citizens from these types of diseases. Still there is a need for real time health monitoring to analyze the patients for early preventive measures and precautions for healthy life. S-Health care IoT has substantial impending for the cognizance of analogues monitoring. It includes the interconnected apps, objects (devices and people), communication technologies, tracking system, and patients’ knowledge base. This paper presents an IoT-enabled model where data collected from the sensors, objects, and people will be gathered at the cloud to take the preventive actions by healthcare professionals. Precautionary measures will be taken by collecting the information about causes of growth of mosquitoes. The suitability of the approach is validated at the base layer of the IoT and data is transmitted to the cloud with the help of edge nodes. From simulations, it is endorsed that the proposed approach is better over ME-CBCCP protocol.</P>
