Figure 8From: An Energy and Application Scenario Aware Active RFID ProtocolTypes of back-off algorithms: constant, linear, linear modulus, exponential, and exponential modulus. The arrow ending at time (randomly chosen by each tag in the range of the ICW) is the initial back-off, then increasing B-numbers show successive back-offs. Shadowed parts show randomness in the back-off time which is added to each .Back to article page
