Performance optimizations for deploying

In the recent past, there has been a tremendous increase in the popularity of VoIP services due to substantial growth in broadband access. However, deploying VoIP over wireless mesh networks presents new challenges, such as packet losses and delays caused by interference in multi-hop environments with limited capacity, which can significantly degrade call quality. This study aims to identify effective strategies for enhancing VoIP service deployment in mesh networks. We present and evaluate various optimizing techniques that improve network capacity, maintain VoIP quality, and manage user mobility efficiently. Through extensive experiments conducted on a real testbed and simulations using ns-2, we offer insights into performance issues and demonstrate the improvements achievable by our proposed methods. Specifically, we find that implementing packet aggregation and header compression can increase the number of supported VoIP calls in a multi-hop network by 2-3 times. Additionally, our fast path switching approach is shown to be highly effective in preserving VoIP quality, while the fast handoff scheme we developed achieves almost negligible disruption during calls with roaming clients.
