摘要：In contrast to traditional cellular wireless networks, power capacity becomes a very constrained and precious resource for ad hoc networks. Many nodes may be powered by batteries with limited lifetime, some of which may not even be rechargeable. For those power-constrained networks, an important issue in routing and multicasting now is to conserve as much power as possible while still achieving good link quality. However, research on multicasting with power control is mostly overlooked. How a multicast routing algorithm can be designed to integrate with power control mechanism therefore becomes our research interest. In this paper, taking mobility into account, a separate distributed tree maintenance algorithm is presented, which consists of two phases: power tuning phase and tree break repair phase.
