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.
