Due to high mobility in MANETs, there exist frequent link breakages which lead to frequent path failures and route discoveries. The overhead of a route discovery cannot be neglected. Broadcasting is a fundamental and effective data dissemination problem. Broadcasting can cause broadcast storm problem. Traditional routing protocols in Mobile Ad-hoc NETwork (MANET) send periodic messages to recognize the topology changes. Sending periodic messages cause overhead. Compared to proactive routing protocols, reactive routing protocols can cause less overhead. This paper presents a survey of various techniques related to broadcasting that can lead to routing protocol overhead.
