چكيده فارسي :
Clustering is an effective approach for organizing the
network into a connected hierarchy, load balancing, and
prolonging network lifetime. Clustering protocols in wireless
sensor networks are classified into static and dynamic. In static
clustering, clusters are formed once, forever and role of the
cluster head is scheduled among the nodes in a cluster. However,
in dynamic clustering the time is divided into rounds and
clustering is performed in the beginning of each round. This
paper presents a Hybrid Clustering Approach (HCA). Whenever
a cluster head consumes a prespecified part of its energy, it
indirectly informs all other nodes so, clustering will be done in
the beginning of the upcoming round. Therefore, clustering is
performed on demand. To evaluate the efficiency of proposal, the
well known distributed clustering protocol, HEED, is used as
baseline example. By means of simulation results, we
demonstrate that significant energy saving can be achieved using
HCA.
