Abstract

Wireless Multimedia Sensor Networks (WMSNs) are mostly affected by bottleneck issues, high packet loss, increased delay, and minimum throughput. One of the most effective schemes towards controlling the bottleneck on the web is traffic control. The WMSNs handle different types of data, hence QoS is essential to afford trustworthy as well as reasonable services towards these kinds of data. The existing congestion control methods, FTLP and FEWPBRC consider the frequency of packet transmission and decide on the output transmission rate of the sink. In the Fuzzy-Based QoS Alert Bottleneck Mechanism, the probability of congestion is predicted by using a fuzzy inference system with three special congestion indicators, and the traffic rate is adjusted based on the priority of the real-time and non-real-time applications. The FBQACC is simulated using the NS2 simulator and it gives an improvement in the average throughput FTLP and FEWPBRC by 7.1499% and 6.3327%, respectively. Similarly, FBQACC reduces average delay compared to FTLP and FEWPBRC by 11.074% and 7.8128%, respectively. The proposed work also gives a minimized average packet loss percentage compared to the existing congestion control methods.
