Mobile Ad hoc NETworks (MANET), are complex and distributed networks that are dynamic. Which are infrastructure less and multi-hop in nature. The communication of a node can be either direct or through intermediate nodes without a fixed and dedicated infrastructure. Hence it is necessary to design an efficient routing protocol for ad hoc network which can address the issues of MANET efficiently. In ad hoc, routing algorithms are classified into nine categories namely: sourceinitiated

This paper presents a survey and to review a comparative study about various routing protocols under each of these categories. Additionally, brief discussions about major routing issues are addressed. This survey paper focuses on the taxonomy related to ad hoc routing techniques and compares the features of routing protocols. In this section, the categories of routing protocols are elaborated in detail manner and the overall performance of the routing protocols in ad hoc network are evaluated for each protocol under various routing categories by considering the following parameters such as route metrics, time complexity, computation complexity and route structure. One of the main features of routing protocols in ad hoc network is the routing metric, which is used to select the best route for forwarding packets. Time complexity (TC) is defined as the time required for the number of steps to perform a protocol operation, communication complexity (CC) is defined as the number of messages exchanged in performing a protocol operation and 2
