We recently presented T-ROME a cross-layer routing protocol for wake-up receivers, along with a Markov chain based framework to model and analyze wake-up receiver based routing protocols. Using this analytical framework, we present here a modification to T-ROME that omits several messages but does not change the basic behavior of T-ROME. We analyze the performance of the modified algorithm and show that the modifications significantly reduce communication energy, time and overhead, especially in noisy environments. Furthermore we present a technique to prevent disconnected network nodes in cases where parent nodes die but preceding parent nodes are alive and in wake-up range.
