                       This paper proposes a new model for evaluating the robustness of the ecosystem for drone
                       projects in a given country, considering nine factors ranging from the regulatory framework to
                       economic and social impact. The objective of this study is to provide a tool in the form of an
                       index that can be used to gauge countries readiness for drone projects. Governments, NGOs as
                       well as commercial drone companies can use the index to gain insights into the possibilities of
                       drones for non-military use. Notable successful projects using drones were used as a benchmark
                       to chart out the various components of the Drone Readiness Index (DRI). We first reviewed
                       selected projects that have attempted to use drone aircrafts for non-military activities, using
                       secondary data. We then quantify the elements of the drone ecosystem and present derivations of
                       the proposed drone readiness index. To show applications and examples of the proposed drone
                       readiness index, we compute the values of the drone readiness index for selected African
                       countries. These values are further presented in a website.

                       Video streaming over HTTP through 4G wireless network used for multimedia applications
                       faces many challenges due to fluctuations in network conditions. The existing HTTP Adaptive
                       Streaming (HAS) techniques based on prediction of buffer state or link bandwidth offer solution
                       to some extent, but if the link condition deteriorates, the adaptation process may reduce the
                       streaming bit rate below an acceptable quality level. In this paper, we propose a machine
                       learning based method, State Action Reward State Action (SARSA) Based Quality Adaptation
                       algorithm using Softmax Policy (SBQA-SP), which identifies the current state (Throughput),
                       action (Streaming quality) and reward (current video quality) at client to determine the future
                       state and action of the system. The ITU-T G.1070 recommendation (parametric) model is
                       embedded in the SBQA-SP to implement adaptation process. The proposed system was
                       implemented on the top of HTTP in a typical internet environment using 4G wireless network
                       and the streaming quality is analyzed using several full reference video metrics. The test results
                       outperformed the existing Q-Learning based video quality adaptation (QBQA) algorithm. For
                       instance, an improvement of 5% in average PSNR and 2 % increase in average SSIM index over
                       the QBQA approach was observed for the live stream.
