Ad-hoc networking is a concept in computer communications, which allows users wanting to communicate with each other to form a temporary network, without any form of centralized administration or infrastructure. Each node participating in the network acts both as host and as router and must therefore be willing to forward packets for other nodes. For this purpose, an efficient routing protocol is needed. The goal of this research is to design a flexible and efficient routing scheme for a mobile ad hoc network (MANET). Because a MANET is composed of wireless mobile computing devices forming an ad-hoc network without existing wired infrastructure or base stations, the network topology changes frequently. Hence, routing in such a dynamic environment is a challenging task. Some previous routing schemes in mobile ad hoc networks include Dynamic Source Routing (DSR), Cluster-Based Routing Protocol (CBRP), and Temporally-Ordered Routing Protocol (TORA), Mobile Agent Based Routing Protocol (MARP) among others. In MANETs congestion occurs due to the packet loss and it can be successfully reduced by involving congestion control scheme which includes routing algorithm and a flow control at the network layer [1]. A Mobile Agent starts from every node and moves to an adjacent node at every time. A node visited next is selected at the equivalent probability. The MA brings its own history of movement and updates the routing table of the node it is visiting [1]. In Mobile Agent Based
