An efficient and reliable message passing by mobile agent

For messages with a variety of characteristics, unicasting, multicasting and broadcasting do not on the whole ensure the optimum efficiency. For the transfer of a message to many receivers, we propose to adopt our messenger agent based on the mobile agent paradigm instead of sticking to the three main protocols. Its autonomy and asynchronous message delivery handle this case in a more efficient and reliable manner compared with unicasting, which is a sender-based message transfer protocol like ours. Of course, we must pay for the creation, migration, and management of it. However, we have justified the employment of our messenger agent by proving the profit from it to overcome the cost. We have considered the buffer requirements at gateways to defend the given drop ratio, the single node delay and the total delay for the entire message delivery path per packet
