Fusion techniques for multi-hop relay wireless sensor networks

摘要: Wireless sensor networks have gained considerable interest in the research community during last decade. In this paper, we target lower layers protocol stack of wireless networks, for aim providing a reliable backbone multimedia applications where error propagation and relatively high rates are major concern. Decoding fusion techniques developed evaluated multi-hop relay incorporating “Amplify Forward” “Decode relaying protocols, based on turbo codes. Simulation results show significant gain bit rate performance when different streams fused at relays or clustering nodes, compared to case these blended final center. Results also that situations transmission conditions do not allow good exploitation multi-stream diversity center, outperforms terms improved BER reduced complexity, expense linear increase rate.
