Focusing on achieving better geographic routing performance of the two-phase geographic greedy forwarding (TPGF) in duty-cycled wireless sensor networks (WSNs) when there is a mobile sink, this paper proposes a geographic distance based connected-k neighborhood (GCKN) algorithm. The algorithm analysis and simulation results show that GCKN can obtain shorter length of the transmission paths explored...
This paper focuses on studying the performance of TPGF geographic routing algorithm with multi routing metric called McTPGF in random duty-cycled wireless multimedia sensor networks (WMSNs). The multi-metric contains the geographic distance and the time, which is called sleeping-delay in this paper, the forwarding node waits to forward packet to the neighbor node after it wakes up. We recognize the...
