Research Institution
In this proposal, Intelligent Automation Inc. (IAI) proposes an innovative Proactive and Adaptive Cross-layer Reconfiguration (PACR) scheme for Reliable Communication in Tactical Networks. The PACR scheme allows the system to adaptively reconfigure its operating parameters in the corresponding layers through proactive prediction, root-cause identification, and cross-layer negotiations. In current wireless networks, the failure occurred in one of the involved layers (e.g., link break at PHY) results in a connection termination; and consequently another connection establishment process has to go through all the layers for a new connection. This process is time-consuming and usually results in an extra latency and resource unavailability within the transition region, which in turn leads to inefficient bandwidth usage and a poor user experience. Moreover, the root cause of connection termination is typical hidden, and not utilized for the repair or reestablishment. The objective of the proposed PACR scheme is to develop an efficient cross-layer negotiation approach to enable proactive and adaptive system reconfiguration, with the final goal of providing users continuous, uninterrupted service without substantial performance degradation, despite various failures may occur frequently in volatile networks.
