Detailed Description

Basic Concept for Cluster Head Decision Modules.

The Cluster Head Decision Component (CHD) is used to elect cluster heads based on selected parameters given by the user. By examining many clustering algorithms we can identify some generic modules that use selected parameters to elect the cluster heads. Such modules can be the Probabilistic, the Identity Based , Energy Based , Node Connectivity and K-Attribute where one or more attributes like sensor readings are used find cluster heads.

As some algorithms elect cluster heads in an almost identical way, CHD modules can be easily reused for multiple algorithms.
