... terminates, all the marked nodes (clusterheads or gateways) form the k-CCS/k-CS. Theorem 2: All the clusterheads (and gateways) marked in CKA form a k-CS (k-CCS) of the networks. This algorithm can be easily extended to achieve k-coverage in O(k log3 n) time with high probability. A randomized clu ...

Yes, because if B1 is true, i.e. we have found wheat grains in Willie’s jaw, the conditional probability of obtaining a match in DNA would be different from the corresponding conditional probability if B2 was true. Now assume for A ...
