Spatial reuse is critical for ad hoc network with limited bandwidth. Exposed terminals are refrained from transmitting in 802.11 like protocols and the network capacity is wasted in high-density ad hoc network. In this paper, we propose a new scheme named SB-FSMA/CA to mitigate the exposed terminals problem in static ad hoc network or mesh network.(More)

To mitigate the problem, this paper proposes a simple and practicable email compression method, effectively reducing emails storage space on mail servers. In our method, emails are MIME-decoded first; then attachments are chopped and duplicate attachments removed; finally the(More)
