To minimize the communication cost and response time, actors are expected to coordinate among themselves to make task assignment to respond service request in Wireless Sensor and Actor Network (WSAN). In the existing solutions, the market-based distributed Simple Auction Aggregation Protocol (SAAP) is suitable for the resource-limited WSAN. A Directional Simple Auction Aggregation Protocol (DSAAP) was proposed based on SAAP, which screened the next-hop child node and restricted the retransmission to reduce the message transmission during auction. The simulation results show that the proposed protocol has lower communication cost compared to the SAAP without performance loss of the optimal node ratio and the distance ratio of the selected to the optimal.
