An Efficient Collision Avoidance Scheme for Healthcare Application

Abstract

Wireless Sensor Network (WSN) has been widely recognized as one of the most important technology for low power wireless communication and also used in variety of applications like medical, military, industrial, agricultural and environmental monitoring. Here, our approach resolve the issues like collision in healthcare application. In healthcare applications of WSN, normally, the generated information's like emergency, cardiac attack, accident etc. which are coming from Patient Body Sensor (PBS) and processed by the sink as soon as possible. It is very much essential to avoid congestion and provide immediate solution without delay. As sensor nodes are battery operated so in all routing protocols designed for WSN, energy should be one targeted parameter. Hence, our proposal is designed not only collect the information centrally but also manage using active queue management (AQM) technique. This technique focuses on queue assisted congestion control type and avoids congestion in the routing phase using multipath and also manages the queue in each node when packet reaches by packet loss probability.
