CGS-accumulation (Consistent Global State Accumulation) is one of the commonly used method to provide fault tolerance in distributed systems so that the system can operate even if one or more components have failed. However, mobile computing systems are constrained by low bandwidth, mobility, lack of stable storage, frequent disconnections and limited battery life. Hence CGS- accumulation etiquettes which have lesser reinstatement- points are favored in mobile environment. In this paper, we propose a minimum-method coordinated CGS-accumulation etiquette for deterministic distributed applications on mobile computing systems. We eliminate useless reinstatement-points as well as blocking of methods during reinstatement-points at the cost of logging anti- messages of very few messages during CGS-accumulation. We also try to minimize the loss of CGS-accumulation effort when any method miscarries to capture its reinstatement-point in an instigation. In this way, we take care of excessive disappointments during CGS-accumulation. We make logging of anti-messages of very few messages only during CGS-accumulation. We also strive to minimize loss of CGS-accumulation effort.
