An Extensive Review on QoS Enhancement in MANET Using Meta-Heuristic Algorithms

Mobile ad hoc network (MANET) is a group of portable devices which it is also defined as a multi-hop and self-organized network. These networks are mainly used for applications like Military, healthcare, disaster recovery, location monitoring, environmental monitoring, etc. With the help of the wireless network, communication between MANETs through routing protocols effectively sends and receives data packets without much packet loss. In order to carry out effective communication, MANET must meet certain quality of service (QoS) requirements. Therefore, QoS in MANET is considered an innovative research area and has to be improved by various techniques. This review mainly aims to improve the QoS using meta-heuristic algorithms in the MANET framework with some parameters such as security, routing, energy efficiency, and mobility. This review also discusses the objectives, challenges, and problems of the MANETs' QoS parameters, and the performance analysis for each meta-heuristic algorithm is summarized in this article. Finally, the future aspects of the checked QoS improvement procedures are discussed.
