Prioritizing based congestion control in MHWSN
Yuechao Wang, Lianglun Cheng · Procedia Engineering · 2011
Achieving different QoS objective in Medium and High Rate WSN (MHWSN) that deals with multimedia information is of concern of researchers. From the application point of view, meeting application specific QoS constraints is important in MHWSN. The transport layer in WSN is to support the reliability and congestion control, which helps in gaining high throughput with minimum end-to-end packet latency. This paper proposes the design of a new transport layer protocol that prioritizes sensed information based on its nature while simultaneously supporting the data reliability and congestion control features. The proposed transport protocol is tested by simulation. Simulation results reveal that prioritizing reduces the End-to-End (E-2-E) latency and retransmitting times for the highest priority.
