摘要: b this paper we present a case for using new power-aware metn.cs determining routes in wireless ad hoc networks. We five ~erent metriw based on battery power consumption at nodw. show that th=e metrics shortest-cost routing algorithm reduces the cost/packet of packets by 5-30% over shortwt-hop (this cost reduction is top 40-70% energy obtained PAMAS, our MAC layer prtocol). Furthermore, these ensures mean time to node failure increased si~cantly. An interesting property packet delays do not increase. Fintiy, note metrim can be used most tradition protocols
