Transport protocol for a real-time communication in wireless sensor actor networks- WSAN

The wireless sensor and actor applications need data that arrive in time and which are necessary for actors to act during a validity time. This demand is fulfilled by a real-time communication for applications that utilize WSAN technology.;The protocols TCP and UDP were not designed for a real-time communication and for a wireless network. The designed protocol---Bonaventura---can manage the data units delay taking into account time and space evaluation. This transport protocol has an entity in every node along the data units' path.;The scheduling mechanism of the protocol determines a data unit priority, which establishes the transmission order of the data units in a node. The traffic shaping mechanism limits the data unit arrival rate to keep the network without congestion. These two mechanisms help the data units to meet their deadline.;The protocol designed in this work was compared with UDP protocol using the mathematical models in MATLAB. The two protocols were compared for the data units travel times and for the timelyput: the throughput of the data units that arrive in time and could be used by the application. It is a protocol with better results---more than 18%---for a 500 sensors and 3 sinks network deployed on a surface of 1000 m by 1000 m and using different values of the transmission rate.
