Research and Thesis Topics for Dynamic Load Balancing in Fog Computing

Dynamic Load Balancing in Fog Computing refers to distributing workloads in a network of fog computing nodes dynamically and efficiently to check the optimal use of resources and reduce the burden on any single node.

It helps to balance the workload among different fog nodes based on their current computational and network capacities and to allocate new tasks to the most appropriate nodes in real time. Dynamic load balancing techniques reconfigure various running applications of transmission services and intelligent data processing.

Dynamic Load Balancing aims to improve the overall system performance, reliability and scalability while reducing latency, cost, and energy consumption.

The dynamic load balancing mechanism applies the current system state and adopts special policies such as:

 •  Migration: Migration defines circumstances for sending tasks from one node to another.
 •  Selection: Selection defines the submission of a task and considers several factors for task selection, such as overhead required for migration, task execution time, and the total number of non-local system calls.
 •  Location: Location defines low-loaded nodes and dispatches tasks to low-loaded nodes.
 •  Information: Complete information is gathered considering system nodes, and decisions are made.

Factors determining the Dynamic Load Balancing in Fog Computing


 •  Resource Availability: The availability of computational and network resources, such as processing power, memory, and bandwidth, at the fog nodes.
 •  Latency Requirements: The real-time constraints on data processing and tasks, including the required latency and response time.
 •  Network Topology: The geographical distribution of the fog nodes and the underlying network infrastructure, including the network bandwidth and latency.
 •  Workload Characteristics: The characteristics of the workloads, including their size, complexity, and resource requirements.

Working principles of Dynamic Load Balancing in Fog Computing


 •  Monitoring: Continuously monitor the status of fog computing nodes, including their computational resources, network capacities, and current workloads.
 •  Assessment: Evaluate the current state of the system and identify potential bottlenecks and imbalances in the workload distribution.
 •  Decision Making: Based on the assessment, decide how to optimally distribute the workloads among the available fog nodes.
 •  Task Allocation: Allocate new tasks to the appropriate fog nodes, considering their current workloads, capacities, and geographical proximity to the data sources.
 •  Re-balancing: Continuously re-balance the workloads among the fog nodes based on changes in the system conditions and the availability of resources.
 •  Optimization: Continuously optimize the load balancing process to improve the performance, reliability, and scalability of the system while reducing the latency, cost, and energy consumption.

Challenges involved in Dynamic Load Balancing in Fog Computing


 •  Heterogeneity: The diversity of fog computing nodes in their computational and network capacities makes it difficult to balance workloads consistently.
 •  Real-Time Constraints: The need for real-time decision-making in the load-balancing process to ensure that data processing and tasks meet the required latency and response time.
 •  Dynamic Changes: The ability to adapt to dynamic changes in the system conditions, including changes in the availability of resources, the characteristics of the workloads, and the requirements of the system.
