Study of Gateway Selection Criteria in Hybrid MANETs

Internet Connected MANETs require the utilization of specific Gateways that enable mobile nodes to exchange packets with external hosts. With this purpose, the Gateways are responsible for providing the mobile nodes of the necessary information to allow the construction of a valid global IP addresses. In some scenarios, mobile nodes may be reachable from different Internet Gateways. Under these circumstances, the mobile node should decide which the best gateway is according to certain metrics. In this paper, two criteria for gateway selection are analyzed. First, the commonly utilized criterion of minimum number of hops to the Gateway is considered. On the other hand, a stability criterion is employed by which a node maximizes the time that it is attached to the selected gateway in order to minimize the number of gateway hand-offs or switchings. The evaluation of the performance of the ad hoc network shows that the gateway switchings can be beneficial if shorter routes are employed.
