On BS/BS Coordination Towards Interference Minimization in WiMAX Networks
Broadband wireless networking is a rapidly evolving research field supported by both industrial and academic communities. Focusing on the Medium Access Control (MAC) layer, IEEE 802.16 protocol family constitutes a prominent technology offering significant advantages in terms of meeting the continuously increasing application demands. However, cross-interference due to co-channel Base Station (BS) transmission residing in adjacent cells constitutes a challenging issue preventing optimum resource utilization in an IEEE 802.16 system thus significantly degrading network performance. In this paper a study on this problem is presented, based on a well-known system level network simulator.
