Balanced MAC [Ozugur98] Variation on p-persistent protocol A link access probability p_ij is assigned to each link (i,j) from node i to node j p_ij is a function of the 1-hop neighbors of node i and 1-hop neighbors of all neighbors of node i Node i picks a back-off interval, and when it counts to 0, node i transmits with probability p_ij Otherwise, it picks another backoff interval, and repeats 292
Balanced MAC degree of node j p_ij is typically = -------------------------------------------------- maximum degree of all neighbors of node i With an exception for the node whose degree is highest among all neighbors of i – For this neighbor k, link access probability is set to min (1,degree of i/degree of k) 293
