A routing delay reduction mechanism based on dynamic switching through congestion prediction in wireless mobile network

Abstract

The advancement in wireless mobile networks (WMNs) and their technologies are becoming the most popular technologies today and are widely used in various communication services. Devices for communication are equipped with wireless network interfaces through which they can efficiently stream data to their network-wide devices. However, due to the extreme use of different services, and TCP incapacity to control congestion, it causes a high overload in wireless communication, which makes the network extremely unstable and congested. Conventional routing methods with congestion control mechanisms for multimedia streams are not reliable for transport layer protocols. In such a case, it makes wireless networks very complex and challenging to perform smooth routing due to its dynamic characteristics and resource constraints. It can be overcome through scheduling flow control in multiple network interfaces for smooth packets streaming data, and even it can play an important role in congestion control by overwhelming the buffers of intermediate nodes and reduction in packet loss. In this paper, we propose a Routing Delay Reduction Approach (RDRA) based on dynamic switching by estimating the transmission rate and delay probability through congestion prediction. The goal of RDRA is to reduce routing latency and packet loss and improve throughput at different traffic rates. Experimental evaluation measures at different traffic rate variation it shows an improved performance in terms of throughput and low latency compared to the related protocols.
