Cluster Head Recovery Mechanism for Hierarchical Protocols


Nahla S. Abd El-Azeem, Sherine M. Abd El-Kader and Mohamed M. Zahra

Due to the big and essential role played by the cluster head in hierarchical protocols of wireless sensor network, it consumes an amount of energy more than the member nodes of the cluster. Therefore, the hierarchical protocols usually suffer from a packet loss due to frequent cluster head failure during the data transmission. This decreases the communication reliability in wireless sensor network applications. Errors caused by data loss inevitably affect the data analysis and subsequent decision making. This paper introduces, the Low-Loss Low-Energy Adaptive Clustering Hierarchy Centralized Protocol (LLEACH-C); LLEACH-C provides a cluster head recovery mechanism, which recovers the cluster heads death during the protocol round operation. This is a missing mechanism in LEACH-C protocol, the protocol that is one of the most popular in hierarchical protocols. The simulation results showed that, LLEACH-C succeeds in decreasing the data packet loss by on average 43% over LEACH-C, and in increasing the lifetime of the network by on average 69.3% more than VLEACH, the protocol that also proposes a mechanism for cluster head death recovery. Furthermore the behavior of the LLEACH-C, in both of the End to End delay and Throughput, are analyzed and compared to VLEACH.
