Quality of Service based Selfish Node Detection in Mobile Ad-Hoc Network

Abstract

Mobile ad hoc networks (MANETs) are wireless networks containing a collection of wireless nodes interrelated with multi-hop communication paths. Mobile nodes can freely create and dynamically self-organize random and temporary wireless networks without pre-existing infrastructure. Hence, the transmission connection between two nodes breaks repeatedly due to node mobility. This causes an additional delay in the network's performance. All mobile nodes work together entirely regarding the distribution of their memory space. In actuality, though, several nodes may inconsiderately choose to cooperate partially; otherwise, not at all with other nodes. These selfish nodes minimize the whole data's accessibility. To solve these issues, quality-of-service-based self-node detection (QSND) in MANET is proposed. In this approach, the Quality of Service (QoS) parameters verifies the operation of a node. This approach uses the QoS parameters like packet loss ratio, packet delay ratio, and remaining energy ratio as the most significant components to evaluate the selfish nodes in the MANET. This approach minimized the delay and improved the network throughput.
