We consider energy-constrained multihop wireless links where the power consumption must be minimized under given requirements on the end-to-end bit error probability. As multihop is known to be able to save transmission energy in a wireless environment, we study the power scheduling schemes over intermediate hops where each source-relay-destination link is modeled as a cascaded binary symmetric channel. The optimal power scheduling problem is formulated with the end-to-end bit error probability constraints. Results show that with the proposed joint power scheduling strategy, a maximum power reduction factor of M is possible in a M-hop route compared with the individual link requirement strategy where each hop assigns power individually to meet certain bit error probability at each intermediate link.
