ABSTRACT
<p><b>Abstract</b>—In most existing localized topology control protocols for mobile ad hoc networks (MANETs), each node selects a few <it>logical neighbors</it> based on location information and uses a small transmission range to cover those logical neighbors. Transmission range reduction conserves energy and bandwidth consumption, while still maintaining network connectivity. However, the majority of these approaches assume a static network without mobility. In a mobile environment network connectivity can be compromised by two types of "bad” location information: <it>inconsistent information</it>, which makes a node select too few logical neighbors, and <it>outdated information</it>, which makes a node use too small a transmission range. In this paper, we first show some issues in existing topology control. Then, we propose a mobility-sensitive topology control method that extends many existing mobility-insensitive protocols. Two mechanisms are introduced: consistent local views that avoid inconsistent information and delay and mobility management that tolerate outdated information. The effectiveness of the proposed approach is confirmed through an extensive simulation study.</p>
