A cross-layer cross-overlay architecture for proactive adaptive processing in mesh networks

Abstract

The dynamic characteristics of wireless mesh network environments make delay-sensitive multimedia applications processing in such networks a very challenging task Cross-layer optimizations are commonly designed to ensure that application requirements are met. Improved timeliness of delivery and precision of information as acquired by a decision- entity can help in effective management of resources and strategies in the mesh network to achieve better application availability, stability, and performance. In this paper, we present an information exchange and database architecture that allows regular updates of cross-layer parameters through distributed database services over an overlay network The architecture provides cross-layer cross-overlay information to enable proactive decision making and distributed optimization for transmission of delay-sensitive application flows in mesh networks. Distributed multi-flow routing optimization over heterogeneous wired + wireless-mesh networks with the suggested information-exchange architecture is also explored.
