Abstract
In this work, we propose to use two optimization meta-heuristics that are: firefly and simulated annealing to extend the life time
of a heterogeneous wireless sensors network (WSN) with a fixed base station by reducing the communication energy
consumption. The proposed approach combines between the clustering and the chain approaches. Our optimization algorithm
tries at first time to find the optimal clustering over the network nodes using the firefly algorithm then inside each cluster it
attempts to find the best chain using simulated annealing. A particularity in our algorithm is the dynamic adjustment of clusters
number over rounds.
