Project on A Data-Centric Multi-Hop MAC Protocol for Underwater Acoustic Sensor Networks

The aim of the DC-MAC: a Data-Centric Multi-Hop MAC Protocol for Underwater Acoustic Sensor Networks Final Year ECE Project is to model the productive protocol of MAC for sensor network of underwater acoustic appropriate for multi-hop network. Distinct prominence based on mid-semester surveys with disputes and chances of underwater communication of Physical channel.

Tone-Lohi (T-Lohi) Protocol includes another reservation and information periods, information period booked by, converting brief tones, and recording the great propagation time (330ms), contention period (CP), accomplished booking when one tone is given to the CP, and back-off if tones are detected.

 Synchronized T-Lohi (ST-Lohi), Synchronized CPs, and tone are given in the starting. This eliminated the uncertainty under time. Waiting the complete CP reduces the uncertainty under space. When contention finds under the CP then the nodes gets back. Nodes do not have greater priority to convert under the second booking time. Since the information time ends, the nodes try to book depending on traffic to determine from last booking time.

 cUT-Lohi permits the conversion at any period. Lengthy data with the duration, Worst condition: CRcUT = 2 Гmax + 2Ttone, Worst condition contender to convert: tc +Ttone+ Гmax –Є, just before it hears C’s transmission, aUT-Lohi decreases CRsUT to greater propagation delay, less contention period, no detection is provided, and CRaUT = Гmax + Ttone.

Conclusion:

It is concluded that the novel methods are to achieve hardware wake up with the help of small (<5ms) tones, small power rate of recording by lengthy times, little duration and hence less collision probability, examine, and count contenders, collision detection results in best utilization, free load, utilize contender to accept back-off to traffic, and enhancing fairness.
