Research on the Traffic Load Issue of WANETs

WANETs is a recent network architecture where the nodes are spread all over the world but behave exactly as if they are part of a single-hop or multi-hop wireless networks at the PHY and MAC layers. Without distinguishing data packets and noise, the Software Defined Access Point (SoDA) samples the wireless channel for the uplink and multicasts the sampled data via Internet to other SoDAs. This leads to tremendous traffic load on the Internet. In this paper, we use energy detection to address this issue. Specifically, we propose EDDD to aim at reducing the traffic load on the Internet under the condition that dropping data packet as few as possible. Through extensive experiments on IEEE 802.11 and IEEE 802.15.4, we validate the feasibility and effectiveness of EDDD.
