A Survey on Cross-Layer Design Approach for Secure Wireless Sensor Networks

Wireless sensor networks comprise of several sensor nodes which are connected to one another with the limitations in computational capacity, battery life, energy resources, and memory. Since the traditional layered approach was adequate for an only wired network, it operates within the boundary which leads to more energy consumption and more communication traffic that impact on overall lifetime and network performance of system architecture. Cross-layer design approach has been introduced to overcome these limitations by allowing the direct interactions between non-adjacent layers and can be applied to bring the optimum energy consumption in wireless sensor networks. In this survey paper, the working scenarios of cross-layer design in wireless sensor networks have been discussed and several cross-layer proposals have been reviewed.
