Multipath route selection policy has been studied in the context of mobile ad hoc networks (MANET). According to the utilization of multiple routes these selection policies have been categorized into two parts: best routing policy and load balancing policy. Many ad hoc routing protocols are based on best routing policy, such as the fastest or the shortest routing policy with local traffic optimization. However, the lack of global perspective might increase congestion resulting in damage of the local traffic. On the other hand, load balancing policy protocols try to avoid traffic congestion by equalizing traffic load of the multipath. But these load balancing policy protocols lost many traffic chances and cause low traffic performance on special condition. In this paper, we illustrate the adverse impact of these two types of route selection policy protocols on mobile ad hoc network and propose a new routing protocol, which switches the route selection policy with consideration of the dynamic network condition. Our protocol is evaluated with Omnet simulator. The simulation results show that the proposed scheme offers a high packet delivery ratio and low packet overhead ratio than other protocols.
