Performance of Heterogeneous Wireless Networks
i) Power, rate, and carrier sense threshold control: To increase the level of spatial reuse in multi-hop wireless networks.
ii) Interference aware routing and scheduling: To improve overall network capacity by exploiting temporal-spatial diversity.
iii) Contention control
for wireless sensor networks: To utilize the wireless channel effectively by adjusting the channel access probability.
