In this paper we present an improved hard acknowledgement deadline protocol in real-time remote procedure call (RT-RPC). Current RT-RPC protocol asks services and waits until the deadline of result. M. Dao and Kwei-Jay Lin (1991) extended RT-RPC by adding hard acknowledgement deadline and got considerable result, to give more time to client recovering error etc. We improved that hard acknowledgement deadline by sending cancel message to the server at acknowledgement deadline when the client did not receive any message from the server by acknowledgement deadline. Upon receiving the cancel message the server kills the current request and executes next message. This scheme will give the client more time to handle requests and the server can do more requests in a given time. To show the effectiveness (more throughput in server) of our protocol we also include our simulation analysis
