Abstract

Most existing localized protocols in mobile ad hoc networks (MANETs), such as data communication and topology control, use local information for decentralized decision among nodes to achieve certain global objectives. These objectives include determining a small connected dominating set (CDS) for virtual back-bone and topology control by adjusting transmission ranges of nodes. Because of asynchronous sampling of local information at each node, delays at different stages of protocol handshake, and movement of mobile nodes, local view captured at different nodes may be inconsistent and/or outdated and may not reflect the actual network situation. The former may cause “bad ” decisions that fail to keep the given global con-straint such as global domination and connectivity, and the latter may incur “broken ” links which in turn will ultimately cause the failure of the constraint. In this paper, we review some techniques that handle inconsistent and outdated local views. These techniques are illustrated using several well-known protocols in data communication and topology control.
