Abstract:
In wireless networking, clustering techniques add scalability,reduce the computation complexity of routing protocols,allow data aggregation and then enhance the network performance. The well known MaxMin clustering algorithm was previously generalized, corrected and validated. In [1] we improve MaxMin by proposing a Single-node Cluster Reduction (SNCR) mechanism which eliminates single-node clusters and then improve energy efficiency. In this paper, we show that MaxMin, because of its original pathological case, does not support the grid deployment topology, which is frequently used in WSN architectures. The unreliability feature of the wireless links could have negative impacts on Link Quality Indicator (LQI) based clustering protocols. So, in the second part of this paper we show how our distributed Link Quality based d-Clustering Protocol (LQI-DCP) has ood performance in high unreliable link nvironments. Performance evaluation results also show that LQI-DCP fully supports the grid deployment topology.
