We discuss agent communication in wireless environment according to FIPA's communication model, which can be seen as a communication stack. From the stack, we focus on the message transport protocols, message envelope layer and agent communication language (ACL) layer. The message transport protocol should provide both efficient and reliable service for the upper layers. We analyze the performance of bit-efficient FIPA-ACL in terms of the output size of an encoded message and the time needed to construct and parse an encoded message. The results show that this encoding is not only the most space-efficient but also proved to be efficient to deal with for instance in message parsing.
