Cross Layer Design and Energy Efficient Protocol for Wireless Sensor Network

Abstract

The Open System Interconnection (OSI) layered protocol model divides networking tasks into layers and defines a set of services for each layer to be provided individually. The design of the protocol makes the services realized for different layers, no direct Communication between nonadjacent layers is permitted as the architecture forbids such an action, also communication is limited to procedure calls and responses between adjacent layers. Whereas the cross layer design violates the reference architecture, by allowing direct communication between protocols at non adjacent layers. It also allows sharing variables between layers, which gives it a better performance in the area of wireless communication.  In order to support better usage of wireless users the cross layer design paradigm has been proposed. This paper covers definition, proposed designs, evaluation, challenges and research issues of cross-layer design.
