Communication has never been the same since the introduction of cellular phones and many apps with varied functions seem to spring up on a daily basis. Various uses appear to spring up on a daily basis. Ad hoc networks were created with the aim of establishing networks made up of linked nodes, on-the-go. Ad hoc networks have many uses, the most common being vehicular ad hoc networks (VANETs) (VANETs). In VANETs, moving vehicles are regarded to be the mobile nodes and mobile vehicular nodes travel at high speeds. Mobility of the nodes makes it challenging to establish reliable communication connections between the nodes and the access points. A technique known as handoff is utilized to bridge this gap and is regarded to be one of the solutions for unreliable communication connections over longer distances. Handoff may typically be observed when the nodes are mobile and start to migrate away from the access points. This article examines and compares different handoff techniques that were presented by various researchers with an aim to enhance favorable characteristics while negating the rest of the components that do not assist in improving the efficiency of the handoff procedure.
