Cross-layer Design for Manets
نویسندگان
چکیده
Routing in MANET is complex due to the fact that the network graph is episodically connected and nodes get only intermittently connected because of nodes mobility, terrain, weather, and jamming that change topology rapidly. In this paper, we propose cross-layer design to achieve a reliable data transmission in MANET. A key challenge is to create a mechanism that can provide good delivery performance and high quality of service in intermittent networks. The key components of our approach include a cross-layer design (CLD) to improve information sharing between different protocol layers. In order to improve the end-to-end performance of MANET, we present mechanism that allows the network layer to adjust its routing protocol dynamically based on SNR and Received Power along the end-to-end routing path for each transmission link. We evaluate our approach using one of common MANET routing protocols, DSR, to illustrate that our CLD improved the performance of DSR.

This paper provides a review of the different Cross Layer Design and protocol tuning approaches that may be used to meet a growing need to support inelastic soft real-time streams in MANETs. These streams are characterised by critical timing and throughput requirements and low packet loss tolerance levels. Many Cross Layer approaches exist either for provision of QoS to soft real-time streams i...
