This paper presents a localized routing protocol for both hybrid adhoc/infrastructure networks and conventional ad-hoc networks. The goal is to extend the network lifetime and to reduce power consumption. Several performance metrics are proposed considering node's transmission power and/or remaining battery capacity. The proposed protocol avoids entire network flooding to reduce interference, delay and excessive overhead. The protocol does not need position (GPS) assistance. Simulation results show that the proposed protocol improves efficiency in both hybrid and conventional ad-hoc networks. The simulation also shows that there is an optimal search radius (power) that the protocol achieves its best performance in terms of network lifetime.
