摘要:

现有大部分的无线自组网广播协议采用最小虚拟骨干子网进行全网广播，能最小化广播的总发送次数。但是，由于未考虑无线链路的不可靠性，这些协议在实际网络中的广播效率并不高。为此，提出了一种高效的全网可靠广播协议（ENWRB），该协议采用网络编码技术减少单跳广播的重传次数，并通过一种基于链路感知的虚拟骨干网选择算法产生更高效的广播骨干网。仿真结果表明，在确保所有节点成功接收广播消息的相同前提下，ENWRB协议的效率显著高于HCA(Hierarchical CDS-based Algorithm)协议。

Abstract:

Most existing broadcast protocols for wireless ad hoc networks use a minimal virtual backbone subnet to broadcast messages,which can minimize the total broadcast transmission number. However,since the unreliability of wireless link is not considered,the broadcast efficiencies of these protocols are not high in real networks. This paper proposes an efficient network-wide reliable broadcast protocol(ENWRB),which adopts network coding scheme to reduce the retransmissions in single-hop broadcast and a link-aware virtual backbone election algorithm to generate the more efficient broadcast backbone. Simulation results show that,under the same premise of ensuring all nodes to receive broadcast message successfully,the efficiency of ENWRB is higher than that of Hierarchical CDS-based Algorithm(HCA) greatly.
