In this paper, the authors first propose a reverse sector mechanism and an optimization division mechanism, which can provide enormous energy conservation benefits. Based on these mechanisms, an efficient sensory data collection mechanism over a cellular-WSN integrated network, named beacon routing algorithm, is proposed to spontaneously renew the local WSN topology according to the position of the UE relative to the location of the beacon cluster under an optimized network division pre-set. Different from the previous studies, beacon routing algorithm achieves the adaptive topology renewal without additional re-clustering overhead. Through performance evaluation, they can implement WSN by making a trade-off between network scale and sector division.
