In the wireless sensor networks the energy of the nodes present in the network is limited. Due to the low manufacturing costs of sensor nodes, they can be deployed in large numbers and having more challenges in topology, routing and data management protocols. Challenges are complicated by severe energy constraints and the inherently unreliable nature of wireless communications. Main objective is to increase the tolerance level and decrease the complexity of the wireless sensor networks. We discuss about fast data collection process with reduced interference and increased the lifetime of the network. We use a heterogeneous configured network (nodes with different coverage range and energy levels), depending on the conditions relay nodes are get selected randomly and data is collected and sends to the mobile sink node.
