Abstract
Strip Wireless Sensor Networks (SWSNs) have drawn much attention in many
applications such as monitoring rivers, highways and coal mines. Packet delivery in
SWSN usually requires a large number of multi-hop transmissions which leads to long
transmission latency in low-duty-cycle SWSNs. Several pipeline scheduling schemes
have been proposed to reduce latency. However, when communication links are
unreliable, pipeline scheduling is prone to failure. In this paper, we propose a pipeline
scheduling transmission protocol based on constructive interference. The protocol first
divides the whole network into multiple partitions and uses a pipelined mechanism to
allocate active time slots for each partition. The nodes in the same partition wake up at
the same time for concurrent transmission. Multiple identical signals interfere
constructively at the receiver node, which enhances received signal strength and
improves link quality. Simulations show that the proposed scheme can significantly
reduce the transmission latency while maintaining low energy consumption compared
with other schemes.
