In many reliable Wireless Sensor Network (WSN) applications, messages have different priorities depending on urgency or importance. For example, a message reporting the failure of all nodes in a region is more important than that for a single node. Moreover, traffic can be bursty in nature, such as when a correlated error is reported by multiple nodes running identical code. Current communication layers in WSNs lack efficient support for these two requirements. The authors present a priority-driven communication layer, called SeNDORComm, which schedules transmission of packets driven by application-specified priority, buffers and packs multiple messages in a packet, and honors the latency guarantee for a message.
