Abstract-In this paper, we have proposed a novel concept called Hilch-hiking in order to reduce the energy consumption of hroadcast application for wireless networks. Hitch-hiking takes advantage of the physical layer design that facilitates the conihining of partial signals to ohtain the complete informatinn. The concept of combining partial signals using ~i m i i n a l ratio combiner [13] has been used to improve the reliahility of the communication channel but has never been exploited to reduce energy consumptinn. We propose a centralized heuristic algorithm called Wireless Multicast with Hitch-hiking (WMH) to construct an energy efficient tree using Hitch-hiking and also present a distrihuted version of the heuristic. We also evaluate the proposed heuristics through simnlation. Simulatinn results show that Hitch-hiking can reduce the transmission cost of broadcast hy as much as 5 0 4 . Further, we prnpnse and evaluate a protcrol called F'SBT that reduces energy consumption of hroadcast hy eliminating redundancy in receive nperatinn. Finally, we propose an algorithm that takes advantage of both Hitch-hiking and PSBT in conserving energy.
REF reduces energy consumption by taking advantage of the physical layer design.
