Study and Implementation of Cross Layer Protocol in Wireless Sensor Networks

Abstract

The rapid evolution of wireless network technology and the explosive growth of wireless network services have made wireless communication an ubiquitous means for transporting information across many different domains. However, there are still some fundamental challenges that need to be overcome in the design of the next generation of wireless sensor networks. The sensor nodes present in the wireless sensor networks are constrained of energy as they are powered with the help of battery. Due to energy limitations there is a great need of providing any energy efficient way of communication for the wireless sensor networks. The traditional method of designing networks using the layered approach might be unsuitable and inefficient for designing wireless networks. Cross layer design is an emerging methodology, which is been implemented in this project to provide congestion control, better routing over the cross layers. This cross layer protocol is designed based on the initiative determination present in cross layer module .The implementation of this initiative determination involves the comparison with the threshold values. The central idea of cross layer design is to optimize the control and exchange of information over two and more layers to achieve significant performance improvements by exploiting the interactions between various protocol layers.
