Architecture for Large Scale Deployment of WiMAX Networks

In this paper we propose a novel totally WiMAX-based architecture for large scale wireless broadband access. To provision scalable QoS, nodes´ traffic should be managed locally. This is achieved through adding some gateway nodes which consequently leads to some cost. In order to realize the proposed architecture, intelligent node placement is primordial such the both cost and performance requirements are satisfied. We thus firstly review the most important node placement works in wireless networks. Then based on distinctive characteristics of WiMAX networks, we provide guidelines on suitable node placement methods in order to deploy the pro.posed architecture in real-life metropolitan scale.
