Description
Application partitioning and code offloading are being researched
extensively during the past few years. Several frameworks for
code offloading have been proposed. However, fewer works
attempted to address issues occurred with its implementation in
pervasive environments such as frequent network disconnection
due to high mobility of users. Thus, in this paper, we proposed a
fault tolerant algorithm that helps in consolidating the efficiency
and robustness of application partitioning and offloading
frameworks. To permit the usage of different fault tolerant policies
such as replication and checkpointing, the devices are grouped into
high and low reliability clusters. Experimental results shown that
the fault tolerant algorithm can easily adapt to different execution
conditions while incurring minimum overhead.
