Abstract This document presents the Centralized Energy Management System (CEMS), a dynamic fault-tolerant reclustering protocol for wireless sensor networks. CEMS reconfigures a homogeneous network both periodically and in response to critical events (e.g. cluster head death). A global TDMA schedule prevents costly retransmissions due to collision, and a genetic algorithm running on the base station computes cluster assignments in concert with a head selection algorithm. CEMS’ performance is compared to the LEACH-C protocol in both normal and failure-prone conditions, with an emphasis on each protocol’s ability to recover from unexpected loss of cluster heads.
