Abstract
Sensors collect data in many ways and provide various services based on that data. Sensors can be distributed or placed anywhere unreachable from human beings. In wireless sensor network environment, it is hard to replace sensor nodes when they fail to operate. In an anchor-based group relay MAC(AGR-MAC), an anchor node can be isolated when any other anchor nodes do not exist in the communication range. And data collected into isolated sensor nodes could be discarded. In order for solving this kind of node isolation phenomenon, we have proposed isolation detection and recovery method for AGR-MAC and prevented the nodes from unwantedly discarding the data.
