Fig. 9From: Hybrid energy-efficient APTEEN protocol based on ant colony algorithm in wireless sensor networkThe life cycle of APTEEN compared in different scales. This figure shows the network life cycle of APTEEN compared 100 nodes with 50-node network topology. The network life cycles of both topologies show a downward trend stably. And the death time of the first node is also very close, so this paper established APTEEN network topology effectivelyBack to article page
