Media medium access control protocol method and system for underwater sensor network

Abstract

The invention provides a media medium access control protocol method and system for an underwater sensor network. The system comprises a request sending information packet module, a time slot number calculating module, a data packet sending module and a verifying module. The request sending information packet module is used for sending a request sending information packet to a receiving node before a sending node sends data. The receiving node used for allocating the rank to the sending node according to the oriental principle and information in a request sending information packet, storing the content in the request sending information packet to a rank list and calculating the time slot number allocated to the sending node according to the content of the request sending information packet. The sending node sends a data packet to the receiving node according to the calculated time slot number. The verifying module is used for conducting verifying after the data packet is received by the receiving node, sending a verification confirming information packet to the sending node and meanwhile ending the time of communication.

Description

Technical field [0001] The present invention relates to the technical field of sensor communication, in particular to a media medium access control protocol method and system for underwater sensor networks. Background technique [0002] With the rapid development of wireless communication and sensing technology, wireless sensor networks have been widely used in many land-based scenarios. Wireless sensor nodes are usually small, very cheap, low power consumption, and easy to deploy. In view of the many advantages of wireless sensor networks, many researchers have tried to transplant ground-based sensor networks underwater to explore the ocean world in recent years. [0003] In 2007, Ian F. Akyildiz, Dario Pompili, etc. published an article titled State of the art in protocol research for underwater acoustic sensor networks at the SIGMOBILE Mob.Comput.Commun conference. The article pointed out that underwater sensor networks will have low energy consumption and shorter The underwat...
