Wireless Sensor Networks (WSNs) are characterized by limited resources in terms of memory, computation power, and energy. As WSN nodes are powered by batteries, they have hard energy constraints therefore, efficient use of energy is one of the main design considerations in wireless sensor networks. Since all layers of protocol architecture influence the energy consumption, exploiting synergies between these layers by a cross layer design will result in an efficient energy utilization of the system. In this paper, the authors have discussed about the importance of cross layer design and the comparative analysis of the various cross layer design protocols.
