Clustering in Wireless Sensor Network (WSN) is one of the methods to minimize the energy usage of
sensor network. The design of sensor network itself can prolong the lifetime of network. Cluster head in
each cluster is an important part in clustering to ensure the lifetime of each sensor node can be preserved
as it acts as an intermediary node between the other sensors. Sensor nodes have the limitation of its
battery where the battery is impossible to be replaced once it has been deployed. Thus, this paper
presents an improvement of clustering algorithm for two-tier network as we named it as Multi-Tier
Algorithm (MAP). For the cluster head selection, fuzzy logic approach has been used which it can
minimize the energy usage of sensor nodes hence maximize the network lifetime. MAP clustering
approach used in this paper covers the average of 100Mx100M network and involves three parameters
that worked together in order to select the cluster head which are residual energy, communication cost
and centrality. It is concluded that, MAP dominant the lifetime of WSN compared to LEACH and SEP
protocols. For the future work, the stability of this algorithm can be verified in detailed via different data
and energy.
