An Efficient Architecture in Next Generation Wireless Networks
Next-Generation wireless networks are proposed to achieve the goal of ubiquitous wireless networking by utilizing heterogeneous networks. The performance of Location management scheme directly affects the overall performance of NGWN at large. This affect significantly impacts on the signaling traffic in terms of the database's waiting time, query and update response time, processing power, bandwidth requirements etc. in the global roaming. Several architectures have been proposed to reduce such traffic. The authors have analyzed the impact of different system parameters with different architectures, one is multi-tier HLR and another is WING architecture.
