Wireless Sensor Networks (WSNs) with their dynamic applications gained a tremendous attention of researchers. Constant monitoring of critical situations attracted researchers to utilize WSNs at vast platforms. The main focus in WSNs is to enhance network life-time as much as one could, for efficient and optimal utilization of resources. Different approaches based upon clustering are proposed for optimum functionality. Network life-time is always related with energy of sensor nodes deployed at remote areas for constant and fault tolerant monitoring. In this work, we propose Quadrature-LEACH (Q-LEACH) for homogenous networks which enhances stability period, network life-time and throughput quiet significantly. c 2011 Published by Elsevier Ltd.

WSNs are considered one of the best sources for monitoring remote fields and critical conditions which are out of range from humans perspective. For optimal distribution of energy among sensor nodes, in order to enhance network life time, suitable protocols and applications should be developed. Based upon optimal probability, selection of cluster heads (CHs) is discussed in homogenous clustering protocol called Low Energy Adaptive Cluster Hierarchy (LEACH) [1], for load distribution of energy within sensors. Moreover, concept of hierarchal and multi-hop clustering distributes energy load more evenly. It is noticed that localized schemes perform well when compared with centralized algorithm in clustering based approaches. On the basis of energy distribution among sensor nodes, WSNs are classified into homogenous and heterogenous networks. Through geographical information and energy awareness of nodes, Geographic and Energy Aware Routing (GEAR) [6] routes a packet towards targeted region. For such process either their exist a closer neighbor or all neighbor are farther away from destination. For closer neighbors from the destination, GEAR picks a next-hope node among all neighbors closer to the destination. In case of distant neighbors their exists a hole and GEAR selects a next-hope node on the basis of minimum cost value. Moreover, Energy Aware
