Abstract

There is a growing trend in developing group communication for mobile computing systems in which mobile host retain their network connections while in transit. In this paper, we present domain-based causal ordering group communication in wireless hybrid network. Our protocol ensures that causally related messages directed to the same destination mobile host will be delivered in an order consistent with their causality, which is important in applications that involve human interaction such as mobile e-mail and mobile teleconferencing. We address group communication that meets causal ordering requirement in a wireless hybrid network. Our handoff protocol ensures smooth migration of mobile hosts while preserving causal ordering property in a wireless hybrid network.
