Nowadays, sensors are being used in a wide spectrum of applications including mission-critical military as well as civil domains. Data dissemination and data aggregation are important aspects of wireless sensor networks. In this paper, the motivation for use of clustering in comb-needle model (CNM) in WSN is presented. Then, the proposed cluster-based CNM (CCNM) is elaborated with suitable illustrations. The outcome of mathematical analysis of the CCNM in terms of communication, computation, and storage overheads is included next. The simulation environment is also explained. This paper is concluded with the performance evaluation of the proposed model in terms of the criteria, namely communication cost, energy consumption, throughput, delay, packet delivery ratio, and packet loss. The communication cost of the proposed model is O(√N/Nc). N denotes the total number of sensor nodes in the network, and N_c denotes total number of clusters identified in the sensor network.
