Clustering is considered as effective data gathering architecture in Wireless Sensor Network (WSN). Whereas limited energy (battery) of the sensor node is considered as the scarcest resource in WSN. In this paper, we explored clustering in terms of energy efficiency for mobile WSN and proposed Mobile Nodes based Clustering Protocol for Lifetime Optimization in Wireless Sensor Network (MNCP). In order to achieve energy efficiency we introduce few mobile nodes, which are randomly deployed across the network. These mobile nodes move in the network when any energy hole or hot spot is formed in the network. It results in improving the life time of the wireless sensor network. To achieve energy efficiency we propose algorithms for energy balanced cluster formation, cluster head selection, intra cluster and inter cluster communication in WSN. Furthermore, using OMNet-4.0 simulation we compared the performance of proposed protocol with LEACH and EEMC using parameters like energy per packet and throughput. Simulation results demonstrated that our proposed protocol is effective in prolonging the network lifetime as well as in improving other QoS parameter like throughput, than LEACH and EEMC
