Estimate the time complexities to execute the following routing algorithms: adaptive decen- tralized routing and lookahead routing.
Adaptive decentralized routing algorithm:
O (N logN) for an SN-DN pair in an N-node network.
Lookahead routing algorithm: O(r log N) for an SN-DN pair with r-hop lookahead (i.e.,
rlookAhead) in an N-node network.
