MEFP periodically selects cluster heads according to the node residual energy,incurs low message overhead,achieves fairly uniform cluster head distribution across the network,and the regular node joins the cluster which has the minimal energy-forward among cluster heads,this tactic can avoid forwarding sensing information circuitously.

提出了一种转发能量最小的无线传感拓扑算法MEFP（Minimal Energy-Forward Protocol），算法减少成簇的通信开销，在网络中簇半径区域内仅产生一个簇头，保证了分簇的均匀；在普通节点加入簇的过程中，选择转发功耗最小的簇头加入，避免迂回发送数据，降低了能量消耗。

By using the character of Cayley graph, we establish the tight upper and the lower bounds of forwarding index for circulant graph.

Packet Radio NetworkIn the network of Ad Hoc, the crunode has a report text to turn hair ability, the correspondence of crunode may pass by to have another an inside a turn of crunode hair, then has been much jump, this be the network of Ad Hoc with other move network of most basically distinct.

在Ad Hoc网络中，结点具有报文转发能力，结点间的通信可能要经过多个中间结点的转发，即经过多跳，这是Ad Hoc网络与其他移动网络的最根本区别。

The invention provides a method for achieving priority level for generating sequence of mapping items which are transformed by network address, the method comprises the following method, first, when an address conversion apparatus needs to converse address after the address conversion apparatus receives a data packet, judging whether the items are generated, upwards sending the data packet to a CPU when a mapping item is not generated, step B, judging whether concurrent mapping number exceeds the preset mapping enqueue threshold with the CPU, if exceeds the preset mapping enqueue threshold, and judging whether a Referer field is contained in HTTP data, and recording the Referer field or a GET field according to judgment result, writing in a REF table, and arraying a priority level for each user according to a write sequence, and step C, leading the CPU to generate map in turn according to the priority level in the REF table, and then sending down to a forwarding layer to transfer a data packet.

本发明提供一种对网络地址转换的映射条目生成顺序实现优先级的方法，包括下列步骤：步骤A：当地址转换设备收到数据包后，需要进行地址转换时，判断映射条目是否已经生成，在未生成映射条目时，将数据包上送至CPU；步骤B：CPU判断并发映射数是否超过预定的映射入队门限，如果是，则判断在HTTP数据中是否含有Referer字段，并根据判断结果记录Referer字段或者GET字段，写入REF表中，并将每个用户依照写入顺序排列出优先级；步骤C：CPU依照REF表中的优先级依次生成映射，然后下发到转发层面转发数据包。

Referring to OpenRouter model, we implement coordination service point by applying the hierarchical coordination model to the transceiver of messages, which facilitates open control. We build plugins-based router adapters based on symbol plugins and functional plugins, which separates control plane from the data plane and supports the dynamical extensibility of router functions.

参考OpenRo路由器模型，利用层次化协同模型实现了独立于数据层的控制平台CSP，奠定了开放控制的基础；基于功能插件和抽象插件构造了基于插件的路由器抽象层PRA，分离了控制与转发平面支持路由器转发平面功能的动态扩展；并举例说明了MER中高效的网络应用控制路由选择机制，体现了直接控制原理，有助于设==计更为复杂的控制策略！

The strategy first determined the type of the node by broadcast information of beacon, the ordinary node forward the packet by greedy method, then forecasting node predict the next node whether to go through the intersection node, and while the intersection node decisioned the direction of routing strategy.

该策略通过信标的广播信息确定节点的类型，是属于普通节点、预测节点或者十字路口节点；然后再判断采取什么样的方式转发数据包，普通节点采取贪婪转发的方式，预测节点采取受限的贪婪转发，而十字路口节点决定路由策略的方向。

Forwarding information is obtained by label in MAC layer and is piggybacked in Request-acknowledgement frame. Clear to send handshake of the downstream node was triggered by RACK that made the data frame transmit consecutively across multi-hop.

在MAC层通过标签获取转发信息并携带在请求－应答帧中发送，触发下游节点的清除发送帧握手，使得数据包多跳连续转发；连续转发概率根据业务类型和节点数据包队列占用率确定，实现了区分服务，避免了节点队列溢出。

A method for retransmitting data in overlay route network include forming overlay route network by laying overlay network node in existing bottom layer network for providing totally transparent overlay route and data retransmission service between user hosts being switched in, packaging and retransmitting as well as unpackaging user IP packet in data retransmission course then sending it to destination host for raising end to end transmission performance.

覆盖路由网络中数据转发的方法属于覆盖网络中的路由和转发技术领域，其特征在于：通过在现有底层网络中部署覆盖网络路由节点形成覆盖路由网络，为接入的用户主机之间提供完全透明的覆盖路由和数据转发服务，在数据转发过程中，用户的IP分组被封装、转发、解封装，最终发送到目的主机，实验表明在较小规模的覆盖路由网络的全连接拓扑里，同时使用跳数受限机制寻找到的路由路径会比Internet路由性能更高，而且底层网络出现故障时，覆盖路由网络能迅速绕过故障区域，从而提高了端到端的传输性能。
