Abstract
Wireless sensor networks are an integral part of Industrial Revolution 4.0. The traffic efficiency of any network depends on link failures and available bandwidth. This paper discusses route discovery in case of a link failure and a control system approach for efficient bandwidth allocation. Control system approach has been attempted to address the twin issues of link failure and bandwidth allocation. The main function of Wireless networks is to gather information about various types of parameters, notably process variables in industries, air quality variables in ambient air monitoring, weather forecasting, cyclonic alertness, congestion and other parameters in traffic routing. The outputs from WSN are feed into Plant systems either to display or control the variables. Naturally for efficient, reliable display and control of parameters continuous supply of information from WSN to Plant systems is important. Hence improving Quality of Service Parameters like signal to noise ratio, fault tolerance, Band width allocation, and stability and load balancing is vital while designing a WSN. We discuss about two QOS parameters in WSN namely Fault Tolerance in case of Link failures and Efficient Bandwidth Allocation. Links here are wireless in nature.
