A Routing Protocol to Evade Congestion in Time Critical Events in Wireless Sensor Networks (ECTCE)

Abstract

Many applications of Wireless Sensor Network (WSN) are designed for vital event monitoring and to ensure timeliness and reliability for the measured environmental values. The communication protocol needs to prioritize the real time data and ensure the timely delivery of the data to the sink node. In this paper, a routing protocol for WSN has been proposed in congestion and delay aware manner to realize highly reliable and timeliness information delivery to the sink. In case of congestion occurrence, it is mitigated by data rate adjustment. The effectiveness of the proposed protocol depends upon how successfully the management packets are delivered, which carries the vital congestion and delay information. A simulation is conducted to investigate the result of the proposed protocol. The results of the proposed protocol have been compared with the similar known techniques and better results are observed
