IACT-MAC: A New Interference Avoidance and Parallel Transmission MAC Protocol
Ning Li, Ping Guo, Juan Zhao · Journal of Applied Science and Engineering · 2015
ABSTRACT Traditional CSMA-based (carrier sense multiple access based) MAC protocol IEEE 802.11 DCF forbids parallel transmission within two hops due to exposed terminal problems in wireless sensor networks. Thus, DCF has achieved interference avoidance at the sacrifice of low throughput. To tackle the problem, this paper presents a new MAC protocol called IACT-MAC. Power control strategy is also introduced to reduce interference. Simulation results show that the implementation of IACT-MAC can achieve high throughput and low latency based on interference avoidance and parallel transmission.
