IEEE 802.15.4 technology provides one solution for low-rate short range communications. Based on the integrated superframe structure of IEEE 802.15.4, a novel low-delay traffic-adaptive medium access control (LDTA-MAC) protocol for wireless body area networks (WBANs) is proposed in the paper. In LDTA-MAC, the guaranteed time slots (GTSs) are allocated(More)
With the advances in micro-electronics, wireless sensor devices have been made much smaller and more integrated, and large-scale wireless sensor networks (WSNs) based the cooperation among the significant amount of nodes have become a hot topic. "Large-scale" means mainly large area or high density of a network. Accordingly the routing protocols must scale(More)
Recently wireless sensor networks (WSN) get great attention in both research and industrial fields. The fast development in WSNs raises many new issues in the field. One of the interesting and of great needs issues is extending the scale of WSN, in order to have large-scale WSNs. In this paper, we propose an enhancement to Pairs Energy Efficient Routing(More)
