Telecommunication is critical at all phases of disaster management. The real-time information before, during and after emergencies would be very valuable in-order to provide emergency services. Due to the development of new low cost satellite systems like nano, pico satellite, there exist a feasible option in providing satellite system in rural area where existing telecommunication infrastructure is indadequate or non-existent. There are various challenges in performance of the on-board satellites system, mainly storage. Hence there exist a need for good buffer management policy to improve the performance of the system. We show that adaptive buffer management optimally exploit the limited onboard resource (buffer size) and therefore to maximize the science return
