Design considerations and comparative analysis of cross layer approaches for terrestrial & underwater wireless sensor networks

초록

Due to the ever increasing demand of the deployment of terrestrial and underwater wireless sensor networks in Internet of Things applications to sense and monitor physical and environmental conditions, it becomes highly essential to design an efficient cross layer framework for Terrestrial and Underwater Wireless Sensor Networks to conserve energy & achieve low delay by considering the design issues involved and challenges encountered in these environments. This paper provides a detailed study on the design considerations and comparative analysis of Cross Layer approaches for Terrestrial & Underwater Wireless sensor networks. The cross-layer design supports in leveraging the performance of wireless sensor networks, and conservation of resources like storage, battery and bandwidth etc. Most of the cross layer architecture designs focus either on limited layers such as MAC and Routing, ignoring the functionalities of other layers or integrate all layer parameters as a single module resulting in increased complexity. This paper proposes a novel Hybrid Cross Layer Model (HCLM) which combines layer interaction through integration and Interface to achieve a good performance across the system. The main aim of the proposed hybrid cross layering model is to achieve a blended efficiency of the layers - Physical, MAC, Routing and Application. This approach, performs the cross layering in two parts - considering one at the middle layers (MAC and Routing) and other at the extreme edge layers (PHY and Application). The proposed model assures the leverage in performance along with the complexity of balancing and maintenance of good data rate resulting in energy conservation. © International Research Publication House.
