| 摘要 |
Interference, collisions, power control, and spatial reuse constitute important issues that need to be resolved urgently in multihop wireless networks such as ad hoc networks, single-hop/multihop wireless LANs, sensor networks, and mesh networks. A method called the evolvable interference management (EIM) method is disclosed in this patent for avoiding/preventing interference and collision and increasing network throughput and energy efficiency in wireless networks. EIM employs sensitive CSMA/CA, patching approaches, interference engineering, differentiated multichannel, detached dialogues, and/or spread spectrum techniques to solve the interference and QoS problems. Also, EIM embodiments based on collision prevention without dialogues are capable of collision reduction/control and can resolve several important problems encountered in previous MACP or RTS/CTS-based protocols, while improving/retaining their important advantages. |
