    Integration of mobile ad-hoc networks (MANETs) into infrastructure-based networks allows mobile users to access other networks. At a network boundary, some node with multiple interfaces plays an important role as a gateway. Gateway discovery mechanism is necessary for mobile nodes to discover nearby gateways but causes message exchange overhead. In order to control the overhead, we present a novel location-Aided gateway discovery protocol with directional broadcast algorithm and Solicitation technique. Simulation results show that our proposed protocol can reduce the overhead, as compared to conventional protocols. Moreover, it improves packet delivery ratio, end-To-end delay, and gateway discovery time.

    Nowadays mobile ad-hoc network (MANET) is focused by many researchers and striving to be deployed in practice. To achieve this goal, these two factors is major problem that we have to consider. The first one is overhead. In the other word, messages that are not necessary to be sent when establish network connection between mobile nodes. The next problem is packet sending rate from source to destination node that high enough to guarantee successful network connection. This paper is focusing on improved the performance of Location-Aided Routing Protocol (LAR) in term of overhead reduction by modifying the algorithm of MANET route discovery process. The result of simulation show that proposed protocol can reduce overhead drastically, expanding network lifetime and increase packet sending rate while comparing with other conventional protocol.
