Adaptive data transmission in WSN using enhanced path assured transmission protocol

Abstract

Wireless sensor network is a highly dynamic network environment and a class of wireless network specially designed for monitoring. Large number of applications such as military systems, object tracking, monitoring, disaster reporting are designed on top of theWSN. These are real-time applications and generate very sensitive data or urgent data. This sensitive information needs to communicate reliably. Accurate delivery of sensitive information has direct impact on the overall performance of the system. Achieving reliability and congestion-free communication is important for the WSN. Some urgent data transmission protocol in WSN mainly focuses on transmission of sensitive data only at the same time it neglects the normal data traffic. Motivated by these challenges, we propose a EPAT system which is autonomous and distributed. This system achieves reliable and congestion-free urgent data as well as normal data communication at the same time.
