The medium access control (MAC) protocol defined in IEEE802.15.4 standard is able to achieve low-power transmissionsin low-rate and short-distance wireless personal area networks(WPANs). The modified CSMA/CA protocol used to minimizepower consumption does not have the hidden-node protectionmechanism, such as RST/CTS mechanism, for the sake of reducingthe control overheads. Referring to previous research results, which proved that the probability of any two nodes in infrastructure network unheard each other is about 41%, the hidden-node problem(HNP) could result in inefficient data transmission in WPAN andquick power consumption. In this paper, we propose a simple andefficient grouping strategy to solve the IEEE 802.15.4 HNP withoutneeding extra control overheads in data transmissions. The proposed strategy groups nodes according to their hidden-node relationships and then separates the periodic transmission period into severalnon-overlapping sub-periods, one for each group. The WPANcoordinator is responsible for detecting the hidden-node situationand performing the grouping procedure if necessary. In this paper,we also prove that the maximal number of groups in a WPAN is five.Simulation results demonstrate that the proposed strategy is able to improve the standard transmission efficiency and to conserve energyby eliminating the unnecessary collisions.
