Minimize Delay Constrain in Wireless Ad Hoc Networks Using Maximum Weight Scheduling

Overview & Implementation

This case study highlights the research assistance provided by TEQ Research Solution for a Ph.D. research project titled “Minimize Delay Constrain in Wireless Ad hoc Networks Using Maximum Weight Scheduling” in the field of Wireless Networking and Scheduling Optimization.The research focused on improving throughput performance and minimizing packet delay in multi-hop wireless ad hoc networks using a hybrid scheduling approach called Ant Colony Optimization Max Weight Scheduling (ACOMWS).

Problem Statement

Traditional scheduling algorithms in Wireless Ad hoc Networks (WANET) suffered from several limitations such as:

• High packet delay

• Increased routing overhead

• Poor bandwidth utilization

• Low throughput during heavy traffic

• Queue instability in multi-hop communication

• Reduced packet delivery ratio

Existing methods including MWS, BP, ACO, Greedy, and GMWS achieved only partial optimization and failed to provide stable scheduling performance under dynamic network conditions.

Proposed Solution

TEQ Research Solution assisted in developing a novel hybrid scheduling framework called ACOMWS (Ant Colony Optimization Max Weight Scheduling).

The proposed model combined:

• Ant Colony Optimization (ACO)

• Max Weight Scheduling (MWS)

The hybrid approach efficiently selected optimal routing paths and scheduling policies based on:

• Path stability

• Link capacity

• Queue length

• Throughput optimization

• Delay reduction

• Packet delivery performance

The research implemented the proposed algorithm using the NS2 simulation platform in a real-time multi-hop wireless networking environment.
