We present two protocols based on this approach. The first protocol uses multicast addresses to filter out unwanted packets without waking up the CPU. Reusability of local addresses, similar to frequency reuse, facilitates using a limited multicast address space. The second protocol advocates a wake-up based scheme to save receiver power in a mobile host. We discuss the tradeoff between energy savings and increase in delay.
Experiments with implementation of these two protocols show that a significant improvement in battery usage can be achieved, making a case for certain features to be provided in hardware.
