一种无线传感器网络中的能量有效性机会路由协议制造技术

本发明专利技术属于无线传感器网络协议技术领域，具体涉及一种无线传感器网络中的能量有效性机会路由协议。本发明专利技术针对传感器网络能量不能再生的性质对传统的机会路由做了修改，将机会路由中的备选转发节点的优先级根据转发节点的剩余能量做调整，将剩余能量较低的节点的优先级降低，剩余能量较高的转发节点的优先级升高。经过转发节点的优先级顺序的调整，剩余能量低的节点来承担实际转发任务的概率降低，从而使得其能量消耗减缓；相反，剩余能量高的节点有更大的机率来承担转发任务。应用这种机制，数据转发任务根据节点剩余能量的多少进行动态的调节，以达到全网能量均衡的目的。

An energy efficient opportunistic routing protocol in Wireless Sensor Networks

The invention belongs to the technical field of wireless sensor network protocol, in particular to an energy efficient opportunistic routing protocol in a wireless sensor network. The present invention according to the nature of sensor network energy can not be on the regeneration of the traditional routing has been modified, the alternative opportunistic routing forwarding node priority be adjusted according to the residual energy of forwarding nodes, the nodes with low residual energy of the lower priority, higher residual energy of forwarding nodes of higher priority. After forwarding node priority adjustment, reduce the probability of low residual energy of nodes to undertake the actual forwarding task, thus its energy consumption slowed down; on the contrary, nodes with high residual energy more likely to undertake the forwarding. With this mechanism, the data forwarding task is dynamically adjusted according to the amount of the remaining energy of nodes, so as to achieve the purpose of balancing the energy of the whole network.
