Abstract
The medium access control (MAC) protocol defined in IEEE 802.15.4 standard is being considered as a promising technology for low-cost and low power wireless sensor networks (WSNs). In fact, the current IEEE 802.15.4 specifications don´t avoid hidden node problem (HNP). In this paper, proposed scheme is dynamic group allocation scheme for avoiding HNP Based on grouping strategy for solving hidden node problem in IEEE802.15.4 LR-WPAN to avoid HNP and to use bandwidth more efficiently.
