This paper presents a novel energy-efficient pulse switching protocol for ultra-light-weight cellular sensor network applications. The key idea is to summerize a single pulse, as opposed to multi-bit packets, as the information exchange mechanism. Pulse switching is shown to be sufficient for event monitoring applications with binary sensing in terms of cellular localization. Event monitoring with conventional packet transport can be prohibitively energy inefficient due to the communication, processing, and buffering overheads of the large number of bits within a packet's data, header, and preambles. The paper presents a joint MAC and Routing architecture for pulse switching with novel cellular event localization.
