Wireless Sensor Networks (WSN) has played a crucial role in many military and civilian applications. However, with the increase in popularity of such networks, the demand for security is also increasing proportionally. The new sophisticated attacks can easily compromise these resource constraint networks such as WSN. In this paper, the authors propose a location and energy efficient routing scheme using identity bases cryptography. They review the classical selective forwarding attack on WSN and see how an identity-based cryptographic scheme using a cross-layer design approach is helpful in circumventing such an attack.
