Medium Access Control

High quality of service (QoS) requirements in multi-priority wireless sensor networks pose new challenges to the Internet of Things (IoT). In a multi-event wireless sensor network (MWSN), nodes generate different types of data packets with different priority such as urgent (high priority) or normal (low priority), with different traffic proportion.

Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is completed even if collisions are detected. All the arbitration takes place without corruption or delay of the message that wins the arbitration.

The study provides a comprehensive picture of the animal feed sector in Vietnam (both supply and demand side) upon data collected from 2 main surveys: feed mill survey investigating the supply side and producer survey investigating the demand side. The results show that, on the supply side, SMEs appear to have less competitiveness than large ones. That is reflected in some aspects such as higher production costs per kg output, using more labor, limited quality control, limited access to capital and land, and many small enterprises have losses.
