Recently Wireless Sensor Networks (WSN) is one of the increasing technologies to provide a service to the network users. WSN is used to transfer the data among the network nodes. To transferring the data, network should provide better communication method among WSN and should provide efficient energy consumption. To achieve this problems many approaches like mobile sink protocol and some other strategies were developed to transfer data through mobile sink mechanisms. These approaches solved only the data transfer problem but fail in solving efficient energy consumption while routing. Sensor nodes usually have limited energy supply and they are impractical to recharge. How to balance traffic load in sensors in order to increase network lifetime is a very challenging research issue. Cluster based wireless sensor network is created with number of sensor nodes and energy efficient cluster head is elected. The mobile collector Sencar collects data from each CH and transfers data to the base station. The proposed load balancing reduces the delay and replacement mechanism will change the cluster head if the energy is loss. Along with the routing procedures the above mechanisms give reliable result in the performance of the network.
