MOVEMENT-AWARE MOBILE ROUTER ADVERTISEMENT FOR POWER SAVING IN VEHICULAR MOBILE NETWORKS

摘要

This paper proposes a power saving scheme for vehicular mobile networks, Movement-aware Mobile Router Advertisement (MMRA). A mobile network moves as a single unit with one or more mobile routers that connect it to the global Internet. A node inside a mobile network is called Mobile Network Node (MNN). MNNs are fixed inside the mobile network, i.e. Local Fixed Node (LFN) or move freely inside the network, i.e. Local Mobile Node (LMN) or Visiting Mobile Node (VMN). Almost all mobile nodes have power restriction since they use batteries for their power. This paper proposes MMRA to reduce the power consumption at MNN by adjusting Router Advertisement (RA) interval in vehicular mobile networks. A Mobile Router (MR) uses information about whether the MR is moving or not. When a mobile network is moving, a new VMN cannot get into the mobile network. So by increasing the interval between RAs when it moves, MNNs can save their power to process frequent RAs.
