Technology is described for configuring data communication schedules for devices. A computing hub in a wireless network may determine a data communication schedule for a device in the wireless network. The data communication schedule may include an assigned time slot for the device to communicate with the computing hub. The data communication schedule with the assigned time slot may be provided from the computing hub to the device. The device may be instructed to wake up from a reduced power mode and enter into an active mode during the assigned time slot defined in the data communication schedule. The computing hub may prioritize data communication for the device during the assigned time slot defined in the data communication schedule and when the device is in the active mode.

Scheduling data communication for devices

A technology is provided for mitigating an attack against a host service. Receive a connection from a client using a first cipher suite to authenticate the client. Identify that a distributed denial-of-service (DDoS) attack is occurring from a plurality of clients. Change the first cipher suite to a second cipher suite wherein the second cipher suite is more computationally intensive than the first cipher suite. Disconnect with the client and causing the client to reconnect using the second cipher suite.

Mitigating a denial-of-service attack

A device driver assignment service registers, in an event-driven compute service, device driver functions for respective IoT devices. The event-driven compute service receives a network protocol message that includes an identifier for an IoT device and an instruction for the IoT device. In response to determining that the network protocol message matches a defined event to trigger a registered device driver function, the event-driven compute service launches the registered device driver function. The registered device driver function translates the instruction into a device driver hardware command for a hardware device corresponding to the IoT device (e.g., within the IoT device). The registered device driver function then transmits, to the IoT device, another network protocol message that includes the device driver hardware command. The IoT device receives the other network protocol message, parses the message to obtain the device driver hardware command, and performs the command on the hardware device.
