From energy conservation perspective in Wireless Sensor Networks (WSNs), clustering of sensor nodes is a challenging task. Clustering technique in routing protocols play a key role to prolong the stability period and lifetime of the network. In this paper, we propose and evaluate a new routing protocol for WSNs. Our protocol; Divide-and-Rule (DR) is based upon static clustering and dynamic Cluster Head (CH) selection technique. This technique selects fixed number of CHs in each round instead of probabilistic selection of CH. Simulation results show that DR protocol outperform its counterpart routing protocols. c 2011 Published by Elsevier Ltd. Keywords: wireless sensor networks, WSN routing protocols, DR-Scheme Spatially dispersed wireless sensor nodes and one or more Base Stations (BSs) are embodied to form WSN. Sensor nodes keep an eye on the physical or environmental conditions at different locations, and communicate efficiently with BS. Generally BS is power rich and nodes are equipped with low power. Applications of WSNs are in security, traffic management, environment monitoring, medical applications, surveillance, etc. Today's research challenge in WSNs is coping with low power communication. Routing protocols in this regard plays a key role in efficient energy utilization. In sending data from node to BS, selection of a specific route, which tend to minimize the energy consumption is necessary. Old fashioned routing techniques are not as energy efficient as present day clustering techniques. LEACH [1], LEACH-Centralized [2] and Multihop-LEACH [3] are few of the earlier techniques of cluster based routing protocols for WSNs. Basically two types of clustering techniques exist; static clustering and dynamic clustering. Clusters once established and never be changed throughout network operation are known as static clusters, while clusters based on some sort of network characteristics and are changing during network operation are known as dynamic clusters. Proposed DR scheme is based on static clustering and minimum distance distance based CH selection. Network area is logically divided into small regions (clusters). These regions are abbreviated as NCR1,
