In Wireless Sensor Network (WSN), the sensors have limitations like energy-constrained nodes, unreliable links, and frequent topology change. In this paper we are trying to propose a routing protocol, which gives better results than any other conventional protocols. The protocol based on Logical Network Abridgement (LNA), used to measure the underlying path diversity and intrinsic network resiliency to congestion, failures and attacks. The proposed protocol focuses on vulnerability index and energy awareness of the node. Using both analysis and extensive simulations, we show that the proposed dynamic routing help achieve the desired system performance under the dynamically changing network conditions.
