Wireless Sensor Networks (WSNs) utilize huge amount of wireless sensor nodes to gather information from their sensing terrain. The gathered information will undergo in-network process and send to the remote sink. In this densely distributed network high packet flow occur near the sink due to the convergent nature of upstream traffic. Congestion may occur in the network and cause packet loss. Due to this packet loss the throughput may be lowered and also, congestion leads to excessive energy consumption. Therefore congestion has to be controlled to prolong the sensor nodes lifetime, in terms of throughput. This paper proposes an agent based upstream congestion control protocol named, Agent-based Congestion Control Protocol (ACCP) for wireless sensor networks. The rate traffic analysis on each node is based on the priority index and the congestion degree of the node. In addition, we comprehensively evaluated the performance of congestion control with multi agent platforms as technology choices and investigated its throughput and latency in three different scenarios
