11. Cross Layer Design
• Cross-layer design is recognized approach for wireless
sensor network protocol design because it provides the
means to adapt all layers to the limited node resources
as well other requirements.

14. Cross layer Solutions
• LRC (Link distance Reliability Cost) based Cross layer
route to improve delivery ratio and decrease the energy
consumption
• Cross Layer scheme Cost Link Based (CLB) to
improve the end to end delay.

15. Cont…..
• TCLM Model to achieve security.
• Cross layer probabilistic data aggregation method for
good quality of service.

16. Conclusion
Cross Layer Approach will be the better solution for
the discussed problems in the Wireless Sensor
Network.
