Multi-Channel Clustering Algorithm for Improving Performance of Large-Scale Wireless Multi-Sink Sensor Networks

This paper presents a simple and distributed clustering algorithm suitable for large-scale Wireless Sensor Networks (WSNs) consisting of several thousands of sensor nodes and few sink nodes. A two-tiered hierarchical architecture is used to increase scalability and ensure performances and durability of such a system: Level 1 called sensor network is partitioned into several equilibrate clusters with one leader or sink by cluster; Level 2 also called sink network is composed by N sink nodes placed in planned manner into monitored region and is connected through IEEE 802.11 radio interfaces. A multi-channel system is used to create a cellular structure by assigning one frequency channel per cluster.
