I am an Assistant Professor of Computer Science and Engineering at the University of Hafr Al-Batin, Saudi Arabia. I teach courses in Machine Learning, Data Science, and Computer Networks.Prior to my current role, I worked as a Research Engineer and Data Scientist at AFRINIC. I planned and delivered research projects which were focused on different aspects of Africa’s Internet from routing protocols to DNS to IPv6 adoption. I also travelled across Africa to deliver workshops and have participated in Internet fora and conferences with the drive to have a common understanding of technologies and policies that are vital in ensuring that the vast majority of unconnected Africans are provided with cheap access to the Internet.I was also a Research Associate at the University of Cambridge and worked on the aRchitecture for an Internet For Everybody, or simply the RIFE project. RIFE was aimed at providing affordable Internet access to those who could not afford it by solving the technological challenge to increase the efficiency of the underlying transport networks and the involved architectures and protocols.I also worked on a project to develop a new mobile web framework designed to revolutionise web access through a significant reduction of the sizes of web pages in order to speed up web access, especially for users in underserved areas. I am proud to say that the work we did contribute to the formation of the Indian-based company GAIUS Networks.My research interests are in Internet Data Science, Internet Performance measurement, mobility on the Internet, mobile web performance, mobile network architectures, Internet provision in underserved areas, and the general interaction between the different players in the Internet Ecosystem. I am also interested in the area of smart livestock farming. The utilization of deep learning algorithms to improve livestock management by building techniques for livestock recognition, behavior recognition, teat detection, yield traits prediction, etc. from images taken by drones.

HTTP Adaptive Streaming on Improved LISP-MN Architecture

Journal of the Institute of Electronics and Computer, 2021

The increasing consumption of video content using mobile devices calls for a more efficient techn... more The increasing consumption of video content using mobile devices calls for a more efficient techniques of handling the enormous data sent and received across wireless Internet. The Loc/ID split architecture is a group of proposals geared towards enhancing the mobility of nodes on the Internet. Although Loc/ID protocols guarantee handover, they suffer excessive packet loss and long service disruption time during the process. In this paper, we posit that redirecting incoming packets to a nearby buffer node, while a handover is taking place, and forwarding the packets to the mobile device after it reconnects will reduce the negative impact of packet loss on user experience. Improvement in the performance of video services is one manifestation that could be observed. In line with this, we propose an improved architecture for one of the most popular Loc/ID protocols, Locator-Identifier Separation Protocol Mobile Node (LISP-MN) by adding a new node, termed loc-server, to LISP-MN components. Loc-server caches and forwards packets to a mobile device during its handover process. To evaluate the performance of the improved architecture, we implemented the system on a laboratory tested and developed a number of MPEG-DASH compliant players. The performance of the players streaming over the proposed architecture is then compared against vanilla LISP-MN architecture. Results of the evaluation show improved performance when running the players on top of the new architecture.

An improved locator identifier split architecture (ILISA) to enhance mobility

The increased use of mobile devices has prompted the need for efficient mobility management proto... more The increased use of mobile devices has prompted the need for efficient mobility management protocols to ensure continuity of communication sessions as users switch connection between available wireless access networks in an area. Locator/Identifier (LOC/ID) split architectures are designed to, among other functions, enable the mobility of nodes on the Internet. The protocols based on these architectures enable mobility by ensuring that the identifier (IP address) used for creating a communication session is maintained throughout the lifetime of the session and only the location of a mobile node (MN) is updated as the device moves. While the LOC/ID protocols ensure session continuity during handover, they experience packet loss and long service disruption times as the MN moves from one access network to another. The mobility event causes degradation of throughput, poor network utilisation, and affects the stability of some applications, such as video players. This poor performance w...

Towards zero packet loss with LISP Mobile Node

2017 International Conference on Computing, Networking and Communications (ICNC), 2017

Host mobility protocols such as Locator-Identifier Separation Protocol Mobile Node (LISP-MN) are ... more Host mobility protocols such as Locator-Identifier Separation Protocol Mobile Node (LISP-MN) are known to experience packet loss at the point of handover. For the duration of the handover, packets sent to the MN via the old access link are dropped by the router since it has no way of knowing where the device has moved to. This affects the performance of transport layer protocols of the TCP/IP stack, which results in degradation of network performance. Buffering these packets close to the MN's new location and forwarding them to the MN on handover completion is one way of improving the overall performance of the mobility protocol. Hence, we introduce a novel network node, locserver, to buffer these packets in order to mitigate the packet loss and reduce the service disruption time (SDT) experienced by MNs during handovers. Using a laboratory testbed implementation, LISP-MN with locserver support shows significant reduction in packet loss and reduced SDT in comparison to vanilla LISP-MN. Similarly, performance analysis of DASH video player also shows the new architecture helps in improving the average video quality downloaded by the MN and reduces the player's instability.

Inter-domain Mobility with LISP-MN -- A Performance Comparison with MIPv6

2015 8th IFIP Wireless and Mobile Networking Conference (WMNC), 2015

To serve as the benchmark for performance, we compare LISP-MN with the IETF standardised MIPv6. We implement the 2 protocols on a laboratory testbed comprising all the nodes necessary for their operation. For multi-interface MNs, LISP-MN shows a better response in soft handover scenarios in terms of throughput and packet loss. MIPv6 on the other hand shows shorter handover delay with lower service disruption time in a hard handover scenario. Both protocols demonstrate poor performance for a single interface MN due to the long handover delay experienced. Although LISP-MN's handover control messages doubled that of MIPv6, our experiments show that it takes a similar time as MIPv6 to complete the handover message exchange.

SIFT-CNN Pipeline in Livestock Management: A Drone Image Stitching Algorithm

Conventional UAV feature-based image stitching techniques significantly rely on the quality of feature identification, made possible by image pixels, which frequently fail to stitch together images with few features or low resolution. Furthermore, later approaches were developed to eliminate the issues with conventional methods by using the deep learning-based stitching technique to collect the general attributes of remote sensing images before they were stitched. However, since the images have empty backgrounds classified as stitched points, it is challenging to distinguish livestock in a grazing area. Consequently, less information can be inferred from the surveillance data. This study provides a four-stage object-based image stitching technique that, before stitching, removes the background’s space and classifies images in th...

Experimental evaluation of the impact of mobility management protocols on HTTP adaptive streaming

IET Networks, 2017

In order to deal with the challenges of heterogeneity of network access technologies and fluctuating resources, which are inherent features of mobile communication, HTTP adaptive streaming (HAS) is becoming the default technology for online video streaming. However, little research has been carried out to better understand the impact of handover schemes of the various mobility management protocols on the video quality of HAS. In this paper we present a comprehensive experimental measurement of the impact of handover on three representative HAS players. First, we implement three existing mobility management protocols, MIPv6, LISP-MN, and PMIPv6, on a network testbed. And using the fluid flow mobility model, the impact of frequent handover on the average video quality, the bandwidth utilisation and stability of the players was investigated. Our results show a degradation of all the observed parameters in all the reviewed players.

An ILNP-based solution for future heterogeneous wireless networks

Utilization of the different wireless interfaces (Cellular, Wi-Fi and WiMAX) that come with many ... more Utilization of the different wireless interfaces (Cellular, Wi-Fi and WiMAX) that come with many of the Mobile Nodes today is central to improving Quality of Experience and Quality of Service in future networks. Although the interfaces are of different technologies as are the access links, the core/backbone networks are now based on IP infrastructure. Efforts to simplify network handover between these technologies – termed vertical handover (VHO) – have not been successful with IP due its mechanism for managing nodes’ identity and location. Researchers have defined and implemented some solutions that proposed the separation of identity of a Mobile Node from its location, and among those proposals is the Identifier Locator Network Protocol (ILNP). In this work, we propose a Linux-based implementation of the ILNPv6 protocol – an instance of the ILNP that is compatible with IPv6 – on laboratory testbed. We also proposed an Information Server managing a defined geographical location we ...

It presents findings related to prevalence of measurement in the region, the reasons why the different business categories investigated conduct Internet measurement as well as the metrics of interest to these entities. The survey also looked at the popular measurement platforms that the respondents use in their measurement activities as well as the platforms that are hosted by businesses and users in the African region. The survey also recorded responses related to data handling and privacy considerations. A total of 123 responses were received from 34 countries. The survey revealed that Internet measurements are not widely conducted in the region largely due to the inadequacy of deployed measurement platforms, the lack of awareness in the subject, and the lack of relevant skills to carry out the measurement tasks. We outlined some recommendations to remedy these issues.
