1 Introduction Mobile ad-hoc networks (MANETs) 1 have no fixed infrastructure, i.e., all nodes can act as traffic sources, sinks, and/or forwarders. Developing core protocols (at different layers, e.g., MAC and network layers) for MANETs has been an area of extensive research in the past few years. Because MANET nodes are often power-constrained, several recent efforts have focused on developing power-aware protocols for MANETs 2 3 4 6 4 7 8 9. One notable example is the Minimum Total Transmission Power Routing (MTPR) 7 which tries to minimize the total transmission power consumed per packet, regardless of the remaining battery power of nodes. Since the transmission power required is proportional to dff, where d is the distance between two nodes and ff between 2 and 4 5, MTPR prefers routes with more hops having short transmission ranges to those with fewer hops but having long transmission ranges, with the understanding that more nodes
