This interconnection is especially required in commercial and enterprise applications of sensor networks where reliable and timely data transfers such as multiple code updates are needed from Internet nodes to sensor nodes. For this type of inbound traffic which is mostly bulk TCP as transport layer protocol is essential resulting in end-to-end TCP session through a default gateway. In this scenario a single gateway tends to become the bottleneck because of non-uniform connectivity to all the sensor nodes besides being vulnerable to buffer overflow. We propose SET a management architecture for multiple split-TCP sessions across a number of serving gateways. SET implements striping and multiple
