Abstract:
A heterogeneous back-off algorithm wherein latency-intolerant messages follow a linear back-off and other messages follow an exponential back-off protocol is disclosed. Typically exponential back-off techniques are used to schedule retransmissions to increase the probability of successful transmission in temporally high contention scenarios. However, exponential back-off can create an exponential increase in the transmit latency. For transmitting latency-intolerant messages like handoff messages large latency is not acceptable therefore a heterogeneous back-off algorithm using both back-off protocols is proposed.
