I design adaptive scheduling and resource-allocation mechanisms for 6TiSCH-based smart-city IoT networks, so that low-power multi-hop networks stay scalable, energy-efficient and reliable as traffic surges and devices move.
Six first-author papers, at IEEE GLOBECOM 2025, IEEE ANTS 2025, IEEE ICC 2026, IEEE GLOBECOM 2026, IEEE ANTS 2026 and IEEE DELCON 2026.
Animated schedule: timeslots across, the sixteen channel offsets down. Cells light up and pulse when their link transmits, a strip beneath shows which of the sixteen physical channels are in use as the offsets hop each slot, and the schedule changes over time: 6P transactions add and remove cells, the slotframe shrinks and grows with traffic, and cells of a node that moved go stale and are rescheduled.
A 6TiSCH network shares one slotframe like this: timeslots run left to right and the sixteen channel offsets top to bottom. Each lit cell is a link scheduled between two nodes, and every slot each offset hops to a different physical channel, so links sharing a slot never collide. My research decides which cells are allocated, when, and for how long, and keeps the schedule valid when the frame is the wrong length, traffic surges or a node moves.
I am a joint PhD researcher at BITS Pilani, Hyderabad Campus, and La Trobe University, Melbourne, through the Asian Smart Cities Research and Innovation Network (ASCRIN). At BITS Pilani I belong to the Department of Computer Science and Information Systems; at La Trobe I am a graduate researcher in Computer Science and Information Technology.
My thesis, Resource Allocation in 6TiSCH-based Smart City IoT Networks, asks how a low-power multi-hop network should schedule itself when traffic is bursty, topology changes and some nodes are on the move. The goal is communication that stays scalable, energy-efficient and reliable without a human retuning the schedule.
I am supervised by Prof. Nikumani Choudhury (BITS Pilani Hyderabad Campus) and Prof. Wei Xiang (La Trobe University, Melbourne).
Eight peer-reviewed papers. The six first-author papers are grouped by the four questions they answer, and each has a project page with the method, results and figures. Two co-authored papers follow at the end.
A slotframe fixed at deployment wastes energy when traffic is low and adds latency when it spikes. These papers let the frame length follow demand.

Adaptive slotframe scheduling that adjusts the slotframe size to the traffic load, improving energy efficiency, latency and scheduling responsiveness in 6TiSCH IoT networks.

An analytical model and adaptive control policy for slotframe adaptation, giving predictable latency and efficient resource use under dynamic traffic.
Nodes near the root forward everyone else's traffic. Allocating cells by position in the routing tree balances load and prevents congestion.

Topology-aware scheduling that allocates resources by node position and traffic conditions, improving reliability, load balancing and congestion management in multi-hop IoT networks.
When nodes move, schedules go stale and reconfiguration itself becomes a cost. These papers predict link lifetime and bound how often the schedule is rebuilt.

A lightweight predictive framework that estimates the residual lifetime of mobile links and feeds it into parent selection and lifetime-aware TSCH cell allocation.
IEEE ANTS 2026. Accepted, to appear.
A churn-bounded rescheduling controller that regulates 6P reconfiguration, manages stale cells, and improves reliability and latency under mobility while cutting control and radio overhead.
Some traffic has to arrive before a deadline, not just eventually. Extra cells only help if they become usable in time, so the scheduler must weigh how fast each mechanism activates against how much capacity it adds.
IEEE DELCON 2026. Accepted, to appear.
An activation-aware planner that chooses, link by link, between baseline service, 6P-negotiated cells and controller-managed cells, and picks the lowest-cost plan that still delivers a deadline-critical burst on time.

Selective CAP Preservation (SeCAP), a delay-aware mechanism that keeps contention access periods in DSME superframes only when the queue calls for them, cutting high-load delay by up to 50% compared with static CAP reduction.

A smart-city 6TiSCH network running in your browser on a 31-slot, 16-channel schedule. Readings climb the RPL routing tree one hop per scheduled cell, each on its hopping channel. A fire alarm floods one path, so 6P adds cells where queues build and releases them once traffic falls; the ambulance switches parent as it drives, its cells are relocated, and its packets jump the queue.
