In energy constrained wireless sensor networks, it was very essential to conserve energy and prolong network's lifetime by using energy efficient protocol. Ail the sensor nodes in these time-critical wireless sensor networks should meet the lifetime constraint at any time instance else it would cause severe consequences that involve economic losses, or even fatalities. This study aimed to maximize the lifetime of wireless sensor networks using Losningen Cross-layer Approach for single base station scenario. Losningen Cross Layer Approach was merged with data link layer and network layer to provide retransmission, monitoring and tracking facilities for the sensor nodes. It would act as an energy-efficient protocol in ubiquitous network and wireless communication by maximizing network's lifetime. Network Simulator 2 (NS2) was used to verify the proposed protocol for maximization of network's lifetime by analyzing the one among the performance metrics, latency. The simulation results showed that the network's lifetime was increased by conserving the energy of the sensor nodes in Wireless Sensor Network. The proposed approach could be used for battle field surveillance where the uninterrupted data would be highly needed, habitat/wildlife monitoring/tracking and environmental monitoring etc.
