An Investigation of Various Versions of AODV Protocol for Discovering Routing Path and Eliminating Packet Loss

Abstract

A Mobile Ad hoc Network (MANET) is a network made up of mobile nodes that communicate through radio. It is a self-contained computer that can be individually programmed, ordered, and controlled. The nodes of an ad hoc network move at their own pace. Ad hoc network nodes are unable to communicate directly with one another due to their short propagation ranges. The topology of the network moves as nodes in a network switch, resulting in frequent route failures. The nodes of the ad hoc network are powered by a battery with a limited energy supply. When a node's battery dies, the network lifespan is shortened, resulting in network loss. Routing is a critical component of MANETs. As a result, Energy Efficient Routing Protocol is chosen to boost network efficiency. There are many routing protocols used to transfer data packets in wireless Ad hoc networks, the most important of which is the Ad hoc On-demand Distance Vector (AODV) Routing Protocol. The key issue with using AODV is that connection errors occur as a result of node movement that is unpredictable. As either the source node or an intermediate node shifts during data packet transfer, the energy in the nodes is lost again due to the additional path exploration process, which occurs several times. This paper provides a literature review of various implementations of the AODV protocol in the form of routing route exploration and packet loss reduction.
