MAClets: Active MAC Protocols Over Hard-Coded Devices

Free registration required

Executive Summary

The authors introduce MAClets; software programs uploaded and executed on-demand over wireless cards, and devised to change the card's real-time medium access control operation. MAClets permit seamless reconfiguration of the MAC stack, so as to adapt it to mutated context and spectrum conditions and perform tailored performance optimizations hardly accountable by a once-for-all protocol stack design. Following traditional active networking principles, MAClets can be directly conveyed within data packets and executed on hard-coded devices acting as virtual MAC machines. Indeed, rather than executing a pre-defined protocol, they envision a new architecture for wireless cards based on a protocol interpreter (enabling code portability) and a powerful API.
