A novel congestion control approach for optimal routing in Wireless Adhoc Networks

Abstract

Summary Congestion is a demanding issue in WANET owing to dynamic routing and resource constraints. Congestion controlling (CC) is a huge concern in attaining equality among e2e flow control and optimal utilization of network resources. In WANET, with distributed resources, if numerous senders compete for a similar bandwidth link, the data rates should be adjusted to avoid network overload that leads to compromises in QoS. This paper introduces a new routing approach with CC model that deployed MAODV for WANETs. Initially, the destination and source nodes are initialized, and subsequently, the MAODV find out the various routing path. Consequently, SGD‐DLNN recognizes all nodes' congestion status in revealed paths. Further, the MAODV assigns traffic in optimal congestion‐less paths if congestion occurs. Here, the black widow‐mutated cat swarm (BWM‐CS) model is deployed to choose the optimal paths based on traffic load density, life span of path, traffic load, remaining energy, link cost, and path distance. Eventually, the advantage of the suggested model is proven.
