Micro sensor nodes are now easily available and are very cheap. These resource constrained nodes are spread in re mote locations to gather data. There are some energy ef ficient clustering protocols that are known to work well for sensor networks. The analyses of these algorithms that have been done in the past are based on the energy con sumption only. In this paper, we develop a performance measure for these algorithms that includes the energy spent, the time delay incurred in the whole process and the infor mation loss. We have formulated a novel metric, the infor mation loss metric, which to the best of our knowledge has not been previously addressed. We then optimize the joint performance measure which is a combination of these dif ferent metrics to yield the optimal clustering configuration.
