A method includes setting, using at least one processor of an electronic device that includes multiple subscriber identity module (SIM) cards, a maximum Network Address Translation (NAT) interval to be a maximum value among NAT keep-alive intervals associated with the multiple SIM cards. The method also includes triggering, using the at least one processor, a partial call setup from a first SIM card of the multiple SIM cards to a second SIM card of the multiple SIM cards. The method further includes determining, using the at least one processor, whether the electronic device receives the partial call setup. In addition, the method includes, in response to determining that the electronic device receives the partial call setup, setting, using the at least one processor, the NAT keep-alive interval for each of the multiple SIM cards to be equal to the maximum NAT interval.

Mobility in a mobile ad hoc network (MANET) can be extended by using fixed network resources to support MANET-level communication between a traveling MANET node and the remainder of the MANET. The IPv6 protocol is used over the fixed network resources to support the MANET-level communication, and mobility-supporting features of the IPv6 protocol are exploited without modifying the IPv6 protocol.

For use in a mobile ad hoc network (MANET), a first MANET node for routing data packets using Layer 2 information. The first MANET node comprises: 1) a radio frequency (RF) transceiver for wirelessly communicating with other MANET nodes; and 2) a controller for receiving incoming data packets from the RF transceiver and sending outgoing data packets to the RF transceiver. The controller receives a first data packet from an Internet protocol (IP) layer associated with the first MANET node, determines a first medium access control (MAC) layer address associated with the first data packet, and adds the first MAC layer address to the first data packet.

The first MANET node comprises: 1) a radio frequency (RF) transceiver for wirelessly communicating with other MANET nodes; and 2) a controller for receiving incoming data packets from the RF transceiver and sending outgoing data packets to the RF transceiver. The controller receives a Route Request (RREQ) message generated by the source MANET node and retrieves initial route cost information from the RREQ message. The initial route cost information comprises an RF link cost parameter for a preceding RF link between the first MANET node and the source MANET node and a node cost parameter for a preceding MANET node between the first MANET node and the source MANET node.
