Abstract In wireless sensor networks, gateway is a hub in data transmission between wireless nodes and Personal Computer (PC). Once the gateway fails, the entire network will paralyze. To ensure the stability of the network, a methodology for the design of redundant gateway based on improved Transmission Control Protocol (TCP) congestion algorithm is proposed in this paper. In this methodology, two gateways physically connected by Ethernet are logically divided into a primary one and a secondary one. Secondary gateway is the backup of the primary gateway. The paper gives an improve method of congestion algorithm, which is applied in this scheme. It can better satisfy the high demands of real-time communication in the embedded system when compares with the traditional TCP congestion algorithm. Experiment shows the effectiveness of improved TCP congestion algorithm, when the primary gateway fails. Secondary gateway can rapidly replace the primary gateway and it ensures a better reliability of the network.
