| 摘 要： | 由于Odd-Eyen路由算法对数据包能够发生转向的位置进行了限制,使得NoP选择策略在选择数据包输出信道的时候必然会优先选择某些固定的方向.这就使得网络节点负载不均衡.所以,该选择策略在具有hotspot类型节点的通信模式中性能较低.文中提出了改进的NoP选择策略(ANoP).该选择策略能够克服NoP选择策略的缺点,使网络流量均匀分布.在ANoP选择策略下,流量在水平方向的传播较远,这就使得它比较适用于非对称的mesh网络.仿真结果表明,在具有hotspot类型节点的通信模式中,ANoP选择策略的平均性能比NoP选择策略提高达24%.

| Abstract: | The Odd-Even routing algorithm1]makes some restriction about the location where the packet can take turns.The NoP selection strategy2],when coupled with the Odd-Even routing algorithm,could give priority to some specified directions,which could result in unbalance in the network payload.As a result,the NoP selection strategy could perform inefficiently in the hotspot traffic scenario.In this paper,the advanced NoP selection strategy is proposed,which could overcome the inefficiency of the NoP counterpart ... |
