Self-organization clustering is based ona variety of studies for MWSNs (mobile wireless sensor networks) as well as WSNs (Wireless Sensor Networks). The size of the sensor field in MWSNs is often larger than in WSNs. When the sensor field is too large, energy inefficiency may result when cluster-heads broadcast an Advertisement Message over the sensor field area.In this paper, we calculate the optimal transmission range for broadcasting an Advertisement Message efficiently. We analyze the number of non-receiving nodes in relation to the transmission range when self-organization clustering protocols are used in mobile environments and propose aTTC (Two-Tier Clustering)method to reduce the number of non-receiving nodes that result when the transmission range is controlled. TTC evenly distributes cluster-head nodes over the network field and prevents any cluster-head clumping generated by self-organization clustering. Consequently, our TTC protocol result in reduced data loss, increased energy efficiency, and enhanced sensor network field robustness by reducing the number of Advertisement Message non-receiving nodes.
