摘要
综合SPEED与SEEM协议,提出了一种混合型协议QoSDM。它针对多数QoS保证的路由协议没有特别考虑到无线传感器节点的能量约束的问题,在sink和多个源节点之间找到多条路径,减少碰撞的发生,利用多个节点代表源节点来接收和转发数据包。多径搜索使用的是全球网络知识,具有先进性。仿真结果表明,既保留了与SPEED相近的可靠性和时延性能,又具有SEEM多路径路由协议的节能QoS保证效率,展现了此协议的潜力和效益。这特别适合于高QoS要求情况下又需要节省能源消耗的情形,符合当前的研究趋势。
By combining of SPEED protocol and SEEM protocol,a hybrid protocol called QoSDM was proposed.It was aimed at the issues which no particular QoS routing protocol for wireless sensor nodes,took the energy constraint into account,in the sink and between multiple sources to find multiple paths to reduce the occurrence of collisions,used multiple nodes on behalf of the source node to receive and forward data packets.Multi-path search used knowledge of global network,which was advanced.Simulation results show that,QoSDM retains the similar reliability and delay performance of SPEED,and has the similar energy efficiency of multi-path routing protocols of SEEM,which demonstrated the potential and benefits of this protocol.This is particularly suitable for the situation of high QoS requirement which also need to save energy consumption,in line with current research trends.
