NS2 Wimax Example Code

Wimax Projects Using NS3 simulator

NS2 Wimax Example Code depends upon Wireless MAN technology. NS3 Wimax is a scalable wireless platform for constructing complementary and alternative broadband networks. A wireless technology optimized for the delivery of IP centric services over a wide area of networks. Download sample NS3 Wimax example code which is used to optimize IP centric service in a wide network for better service.

NS3 Wimax Example Code

Types of services offered by wimax:

  • Non-line-of-sight.
  • Line-of-sight.

Types of usage models in IEEE 802.16:

  • Fixed usage model (IEEE 802.16-2004).
  • Portable usage model (IEEE 802.16e).

Scope for introducing wimax:

  • It can help service providers meet many of challenges they face due to increasing customer demands.
  • WIMAX can satisfy potential applications like filling gaps in cable, extending broadband capabilities to bridge them closer to subscribers etc.
  • WIMAX can support very high bandwidth solutions where large spectrum deployments are desired using existing infrastructure keeping cost down.
  • WIMAX, which is an IP-based wireless broadband technology, can be integrated into both wide-area 3G mobile and wireless networks.
