Abstract: In order to reduce the energy consumption of nodes and improve the transmission capacity of data in the process of building wireless sensor network at the cognitive sensor node,a new time-limited energy-efficient protocol based on stability was proposed.The protocol introduces a stability factor through employing the channel model to mo-del by authorized users and studies the relationship between path selection and system energy consumption by adjusting the stability factor constantly to find a reasonable path choice which is least affected by users,thus reducing the times of link failure,improving data transmission capacity,ensuring the lesser energy consumption,and achieving the goal of effectively balancing the network energy and extending the network lifecycle.The simulation results are consistent with the theoretical analysis and show that the proposed protocol has better performance in energy consumption and data transmission capacity.

Key words: Cognitive wireless sensor network, Energy efficiency, Network life cycle, Stability
