Research Problem
Understanding existing clustering algorithms and finding the problems stated and addressed
Compare the pros and cons of each algorithm
Simulate algorithms and compare performance with and without clustering mechanism
INTRODUCTION TO CLUSTERING
Grouping of similar objects or sensors in our context
distance or proximity
Logical organizing
Topology control approach
Load balancing, network scalability
Types of clustering
Static: local topology control
Dynamic: changing network parameters
Single hop and multi ho
Homogeneous and heterogeneous
ADVANTAGES OF CLUSTERING
Transmit aggregated data to the data sink
reducing number of nodes taking part in transmission
Useful energy consumption
Scalability for large number of nodes
Reduces communication overhead for both single and multi hop
CONCLUSIONS
Problem statement seems to be unique
Reduce energy consumption
Prolong network lifetime
Form set of clusters from a set of nodes
Cluster the whole network with the selected CH
Rotate CHs for energy distribution
Algorithms differ in CH selection and cluster formation
Some address intra and inter cluster communication
Some address real world applications
