Abstract
In low-power, low-rate wireless networks, IEEE 802.15.4 is a standard protocol. Devices in such networks are typically battery-operated; the radio transceiver is short-range yet power-hungry. Antenna orientation, inter-node distance, and channel selection all affect reliability. We evaluate IEEE 802.15.4 link performance using Zolertia Z1 motes in indoor and outdoor scenarios. RSSI decreases with distance and is affected by mote height and antenna polarisation; LQI and packet delivery ratio are largely unaffected. Non-interfering channels 26 and 15 are similarly affected by Wi-Fi. Contiki MAC outperforms XMAC.

I am Waleed Iqbal, an Assistant Professor in Data Science at Northeastern University, based at their London Campus.

I also hold positions of Teaching Fellow in Computer Science at the School of Electronic Engineering and Computer Science, Queen Mary University of London and Associate Lecturer at Arden University London.

I received my PhD in Computer Science under the supervision of Dr. Ignacio Castro and Prof. Gareth Tyson in the Social Data Science (SDS) Lab, Networks Research Group at Queen Mary University of London.

My research interests are broadly in manifestation of socio-economic inequality in online user activity.

Previously, I worked at IHSAN Lab in Information Technology University Lahore, Pakistan, supervised by Prof. Dr. Junaid Qadir as a postgraduate thesis student, affiliated researcher, and teaching assistant.

Since September 2023, I am endorsed and recognised as UK Global Talent (Exceptional Promise) in the Research and Academic Category by the Royal Academy of Engineering UK and granted Global Talent Visa by the Government of the United Kingdom.
