Recent Advances in Checkpointing Techniques in Mobile Computing Systems
This paper covers recent development that has taken place in fault tolerant techniques in mobile computing systems. A mobile computing system is a distributed system where some of the nodes are mobile computers. It consists of fixed node called Mobile Support Station (MSS) and number of Mobile Hosts (MHs). A cell is a geographical area around a MSS in which it can support a MH. A Mobile Host can change its geographical position freely from one cell to another or even to an area covered by no cell. All the communication from one Mobile Host to another Mobile Host goes through MSS. MSS has both types of links-wired and wireless links.
