Load Balancing in Multi Interface Wireless Mesh Networks

Bol

The proposed MIMC WMN under study introduces a third layer (i.e., cross layer 2.5) between layers 2 and 3, which includes a new module called packet SCHEDULER; this is a generic C++ structure that can implement MAC mapping for the interfaces of neighbouring hosts and distribute traffic (i.e., load balancing) in multi-hop mesh networks, while collaborating with the implemented routing protocol and utilising two or more interfaces in each node. When a MIMC simulation framework capable of establishing a symmetric (i.e., bidirectional) link in a WMN was developed by adapting the OLSR protocol, the aforementioned load balancing algorithms were then implemented in a multi-hop MI WMN, and the performances (throughput, end-to-end delay, PER) of all load balancing modes (with two interfaces) were compared to those of the three-interface round-robin WMN and the multi-hop single-interface (SI) WMN. Load balancing algorithms in a multi-channel WMN enhance the route between all traffic and improve the capacity of links over the mesh networks. This book has added experimental performance of chain, grid and random topologies.
