Abstract
Relay node placement is one of the critical need of wireless sensor
networks when connectivity, lifetime, fault tolerance like factors are
desired in the network. In this study, we review the present relay node
placement techniques and provide an overall view of this study by
summarizing previous achievements. We categorize the placement
strategies into four broad categories, namely, approximation,
algorithms, heuristics, meta-heuristics based techniques. A taxonomy is
presented to enlist the present techniques. The paper also emphasizes on
the research challenges and gives an idea of potential future scope in
this research domain.
