Abstract
Heterogeneity in sensor nodes may be caused because of differences in transmission capabilities, different terrains or different distribution of event occurrences. A distributed, energy efficient clustering protocol, Distributed Lagrangean Clustering Protocol (DLCP) based on Lagrangean Surrogate optimization is proposed for heterogenous networks. DLCP uses residual energy and position of the sensor nodes for the election of cluster heads. Cluster head election is modeled as a facility location problem. Simulation study reveals that DLCP forms better clusters than HEED (Hybrid Energy Efficient Distributed Clustering) and LEACH. DLCP prolongs network lifetime by distributing energy usage in a more uniform manner.
