It is important of Agent communication for the reality of coordination, cooperation and consistency in multi-Agent system. In this paper, an architecture of Agent communication is given. In order to decrease the working capacity to maintain the communication protocol, using the KQML as the basic Agent communication language, the paper proposes an Agent communication model based on dynamic modif...

This paper presents the pattern language for specification of communication protocols. The pattern language contains four levels which are used to specify communication protocol and its messages. These four levels of this pattern language are: high-level protocol specification, protocol structure specification, message specification, and detailed message specification. Several existing patterns...

We study the wireless communication among highway vehicles in the newly-assigned 5.9 GHz Dedicated Short Range Communication (DSRC) spectrum. A vehicle-vehicle Location-Based Broadcast (LBB) communication protocol is designed to meet highway safety applications’ communication requirements. The analytical expressions of the performance of the protocol in terms of probability of transmission fail...

We present a real one-time-pad key communication protocol that allows the secure direct communication. With the quantum nonlocality, Alice and Bob (the communicators) can send message to each other in a deterministic manner by using local operations and a reliable public channel. The security of this protocol is based on the ‘High fidelity implies low entropy’. Actually, the eavesdropper-Eve ca...

Quantum key distribution (QKD) is a protocol which is provably secure. Eve cannot gain any information from the qubits transmitted from Alice to Bob without disturbing their state. First , the no-cloning theorem forbids Eve to perfectly clone Alice’s qubit. Second, in any attempt to distinguish between two non-orthogonal quantum states, information gain is only possible at the expense of introd...

In distributed applications, a group of multiple application processes have to send and receive multimedia messages by using the high-speed network. The multimedia message at the application level is decomposed into multiple smaller packets which are transmitted in the communication system. In this paper, we discuss the atomic and ordered delivery of messages at the application level rather tha...
