We define a MANET route discovery protocol particularly suitable for networks that exhibit a rapid changing topology. LDRP relies on an auxiliary sensor network to gather localization information of nodes and makes use of this information to identify links of high residual lifetime for communications. In simulation, we show that LDRP outperforms the level of service provided by a flooding based algorithm. This advantage is clearly seen in terms of both higher throughput and lower packet loss for UDP or TCP based traffic. © 2006 IEEE.
