This technology case study focuses on the routing protocols used in mobile ad-hoc networks. For any wireless ad-hoc network, routing is the main concept. Proactive and reactive routing protocols are two such approaches. The ever changing properties like asymmetric links, low transmission power and topology have always been a challenge for the routing protocols. Under such circumstances, the proactive and reactive routing protocols have proved to be inefficient. Each of these approaches has its own disadvantages. To overcome these disadvantages, hybrid routing protocol has been designed. This paper will provide an overview of all the three above mentioned protocols namely proactive routing protocol, reactive routing protocol and hybrid routing protocol with an example each. A comparison between the three routing protocols is also provided in this paper.
