Background/Objectives: Sensor nodes will be in fixed/mobile locations. The exchanges can also be huge that it may result in overlapping or loss of packets. This will lead to heavy overhead and less packet forwarding ratio. A layer level model will be a good solution. Methods/Statistical Analysis: In this research work, Hierarchical Hybrid Model based clustering is proposed to combines the merits of both hierarchical and hybrid approaches in routing for improving the lifetime of the network. A mathematical model is being proposed for a wireless sensor network. It consists of following phases. Layering Design, Clustering, Multilayer clustering, Region categorization. The model is improved as it has facilities for clustering and routing based on combined layered approach. Findings: For simulation, the network simulator tool (NS 2) is used. The performance of the proposed scheme has been shown in graphs for the metrics namely, Total consumed energy, control overhead, good put, throughput, delay, packet delivery ratio and lifetime. The paper provides conclusions how the longetivity of the network is improved by combining hierarchical and hybrid approaches in routing. This approach can be applied for users in indoor environment.
