The mobility for communication devices has generated the requirement of next generation wireless network technology development, several type of wireless technologies have been developed and implemented, one of them is ad hoc mobile network system which facilitates to a cluster of mobile terminals which are animatedly and randomly changing locations in such a way that the interconnections need to be handled continually. A routing procedure is used to find the routes between the mobile terminals in the set of connections for easy and reliable communication; main purpose of this protocol is to find a proper route from caller to called terminals with minimum of overhead and bandwidth consumption during construction of route. This paper provides an impression of a broad range of routing protocols projected in the literature and has in addition provided a piece comparison of all routing protocols with discussion of their respective merits and drawbacks.
