The resource limited nature of WSNs require that proto- cols implemented on these networks be energy-e±cient, scalable and dis- tributed. This paper presents an analysis of a novel combined routing and MAC protocol. The protocol achieves energy-e±ciency by minimizing signaling overhead through state-less routing decisions that are made at the receiver rather than at the sender. The protocol depends on a source node advertising its location and the packet destination to its neighbors, which then contend to become the receiver by measuring their local op- timality for the packet and map this into a time-to-respond value. More optimal nodes have smaller time-to-respond values and so respond before less optimal nodes. Our analysis focuses on the physical layer requirements of the system and their e®ects of di®erent system parameters on per hop delay and total energy used. Some examples of mappings are examined to obtain analytical results for delay and probability of collision.
