Collision Classification MAC Protocol for Underwater Acoustic Communication Networks Using Directional Antennas
文献摘要：
Traditional underwater acoustic commu-nication networks(UACNs)generally use omnidi-rectional transmission technology that causes a large number of data-packet collisions,thus resulting in low network throughput and high end-to-end delays.Com-pared with omnidirectional transmission technology,directional technology only sends and receives data packets in a specified direction.This can significantly reduce the probability of collisions and improve net-work performance.However,it also causes a deafness problem,which occurs when the sending node sends a data packet to the receiving node but the receiving node is unable to reply to the sender,because its an-tenna beam is closed.To resolve this issue,this study proposes a collision classification media access con-trol(CC-MAC)protocol for UACNs.With this pro-tocol,the underwater acoustic channel is divided into two subchannels,and the nodes transmit correspond-ing data types on them.The sending node can estimate the current status of the receiving node(i.e.,no colli-sion,normal collision,deafness)according to the type of the data packet received and the sub-channel it ar-rived on,and it can choose correct options to improve network efficiency.Finally,we verify the performance of CC-MAC via simulations,showing that the protocol achieved higher network throughput and lower end-to-end delays.
