In this paper we discuss a novel multihop transport scheme for wireless sensor and actor networks (WSAN) that facilitates (a) reliable multihop data packet transmission from the sensor nodes to a centralized controller (sink), and (b) reliable multihop control packet transmission from the sink to different actor nodes. The transport scheme works on a model of prioritized packet store-and-forward mechanism which enables important information to reach its destination with minimum delay. We also employ congestion avoidance and control mechanism. Simulations are conducted using network simulator (ns-2) tool to study the performance of the proposed scheme.
