Abstract Based on the study on communication situation of mobile ad hoc network (MANET) accessing Internet and taking the gateway important function of accessing network into account, a MANET accessing Internet routing algorithm based on dynamic gateway adaptive selection (MRBDAS) is presented. It considers candidate gateways’ connecting degree, load degree, residual energy, and movement rate synthetically and uses the idea of group decision-making method for reference. The algorithm employs the methods of multipaths and query localization technique based on old path information to maintain routing adaptively. Compared with the existing accessing routing algorithm based on dynamic gateway, the algorithm demonstrates in its simulations that by bringing dynamic gateways colony function, the MRBDAS can improve network throughput, reduce average transmission delay of data packets and routing overhead, and prolong accessing network life. The validity of MRBDAS has been proven.
