Hitch-hiking takes advantage of the physical layer design that facilitates the combining of partial signals to obtain the complete information. The concept of combining partial signals using maximal ratio combiner [13] has been used to improve the reliability of the communication channel but has never been exploited to reduce energy consumption. We propose a centralized heuristic algorithm called Wire-less Multicast with Hitch-hiking (WMH) to construct an energy efficient tree using Hitch-hiking and also present a distributed version of the heuristic. We also evaluate the proposed heuristics through simulation. Simulation results show that Hitch-hiking can reduce the transmission cost of broadcast by as much as 50%. Further, we propose and evaluate a protocol called PSBT that reduces energy con-sumption of broadcast by eliminating redundancy in receive operation. Finally, we propose an algorithm that takes ad-vantage of both Hitch-hiking and PSBT in conserving en-ergy.Publication Metadata only On Understanding Transient Interdomain Routing Failures(2009-01) Wang, F; Qiu, J; Gao, LX; Wang, JPublication Metadata only Cooperative robust forwarding scheme in DTNs using erasure coding(2007-01) Liao, Y; Zhang, Z; Ryu, B; Gao, LPublication Metadata only How to lease the Internet in your spare time(2007-01) Feamster, N; Gao, LX; Rexford, JPublication Metadata only On characterizing BGP routing table growth(2004-01) Bu, T; Gao, LX; Towsley, DPublication Metadata only The monitoring and early detection of Internet worms(2005-01) Zou, CC; Gong, WB; Towsley, D; Gao, LXPublication Metadata only On inferring autonomous system relationships in the Internet(2001-01) Gao, LX
