摘要:
无人机自组网应用场景中,针对OLSR(Optimized Link State Routing)协议在数据通信阶段,无人机快速移动可能引起通信链路中断,并且OLSR协议没有链路维护机制,导致发包成功率降低和时延增加.在节点入网阶段,无人机无法及时获取全网拓扑信息,导致通信失败.本文借鉴AODV(Ad Hoc On Demand Distance Vector)路由协议中按需寻路思想,提出一种按需寻路的可靠OLSR协议.该算法提出了两个优化思路:基于TC全网寻路机制和基于HELLO邻居寻路机制,通过增加路由获取途径,维护多跳链路的稳定性.通过仿真实验将该协议与现有协议进行比较,实验结果表明,该协议在不增加控制开销的前提下,提高网络的发包成功率,端到端时延和吞吐量.

为适应无线网络拓扑结构的动态变化和无线信道的不稳定性,针对三层路由的QoS较大受限于网络拓扑结构变化的缺陷与不足,研究并实现了一种无线网络二层交换路由协议算法.算法主要研究按需路由策略,针对无线网络特点介绍了路由表设计原则,进一步给出了路由表以及按需路由报文格式、按需路由流程与二层路由转发流程及其实现,并通过实验对比对协议进行性能分析.实验结果表明,该算法有效降低了动态拓扑的无线网络路由建立时间.%In order to adapt to the dynamic changes of the wireless network topology and the instability of the wireless channel, in view of the defects and shortcomings that the QoS of layer 3 routing is greatly limited by the change of network topology, a wireless network layer 2 switching routing protocol algorithms is analyzed and implemented. The on-demand routing strategy for the algorithm is discussed. The design principle of routing table is described in view of the characteristics of wireless network. In addition, the routing table, the message format of on-demand route, the on-demand routing process, layer 2 routing forwarding process and its implementation are given. The performance of the protocol is analyzed by experimental comparison. The experimental results indicate that the algorithm can effectively reduce the routing establishment time of wireless network in dynamic topology.

摘要:
移动自组织网络(MANETs)是无基础设施、由移动节点构成的动态网络.MANETs的移动特性给路由协议的设计提出挑战.为此,以典型的按需路由(AODV)为基础,提出基于链路稳定的MANETs路由协议,记为LSR.首先,分析了AODV的路由过程和不足,再计算节点能量寿命和链路寿命,然后通过比较能量寿命和链路寿命,构建候选转发节点集,最后,从链路稳定性角度,选择下一跳转发节点.实验结果表明,提出的LSR协议降低了路由开销,提升了吞吐量.与AODV相比,LSR协议的路由开销降低了近50%,吞吐量提高了23%.

摘要:
传统移动Ad Hoc网络(mobile Ad Hoc network,MANETs)黑洞攻击解析模型存在网络拓扑结构固定、网络传输性能预测精确度低的问题.针对使用按需路由协议的MANETs网络,提出一种基于随机拓扑近似技术的黑洞攻击解析改进模型(improved black hole attack analytical model,IBAAM).IBAAM协议使用随机模型代替传统解析模型使用的n元2立方体模型,并将网络结构扩展至随机拓扑结构,使用最短跳距离概率描述表示网络拓扑结构的随机拓扑信息,再使用K均值聚类法实现跳距离文件配置以求解任意拓扑结构下的攻击概率问题,从而在不利用任何实际拓扑先验信息条件下有效预测MANETs网络平均丢包数目.IBAAM实验结果表明,在多种不同固定Ad Hoc拓扑结构下,IBAAM的网络丢包预测精确度在仿真结果的95%置信区间内,能够有效预测网络传输性能.%The problem of the traditional analytical model of black hole attack for mobile Ad Hoc network (MANETs) is lower prediction accuracy for network transmission performance.Hence,for an ad hoc network with on demand routing protocol,a novel black hole analytical model was proposed based on stochastic topology approximation technology.IBAAM employs a stochastic analytical model instead of n ary 2 cube model used in the traditional analytical method,and expands the topology into the any arbitrary network topologies.It employs the shortest hop distance probability to represent the random information of network topology,and uses K-means clustering method to realize the hop distance file configuration to compute the attack probability,which can predict the average packet loss of the networks without using any given information about practical network topology.The IBAAM experiments showed,under variety of the fixed Ad hoc topology,the average prediction accuracy rate of the network packet loss of the analytical model proposed is about 95% of packet loss in the simulation results.

摘要:
随着无线传感网络WSNs(wireless sensor networks)的广泛应用,同一区域被多个WSNs重叠覆盖已成普通现象.在这种情况下,可通过多个WSNs间协作传输数据包,提高多个WSNs的寿命.为此,对多异构网重叠区域能耗均衡的协作路由进行研究,提出基于路由寿命的协作路由RLCR(routing lifetime-based cooperative routing)算法,均衡了各异构网的能耗,提高了它们的网络寿命.RLCR算法引入了能够多信道转发数据包的共享节点,它们能够与任何WSN通信.同时依据按需路由协议AODV(adhoc on-demand distance vector)建立路由表,并依据路由寿命选择路由,尽可能地延长各网络寿命.仿真结果表明,与基于EBCR算法相比,RLCR算法提高了网络寿命和时延性能.%As wireless sensor networks ( WSNs) are widely diffused, multiple overlapping WSNs constructed on the same ar-ea become more common. In such a situation, lifetime is expected to be extended by cooperative packet forwarding. Therefore, energy-balanced of multi-heterogeneous WSNs overlapped area-based cooperative routing was analyzed in this paper, and the rou-ting lifetime-based cooperative routing ( RLCR) was proposed. It balanced energy consumption of multi-heterogeneous WSNs, and prolonged its network lifetime. RLCR protocol introduced shared nodes that can use multiple channels to relay data packets, and can communicate with any WSNs here. In RLCR protocol, each sensor node creates its routing table based on Ad Hoc On-demand Distance Vector ( AODV) , and selects the route with maximum route lifetime. Simulation results show that RLCR out-perform in terms of lifetime and delay, compared with EBCR protocol.

摘要:
On-demand routing protocols,such as AODV (Ad Hoc on-demand distance vector)routing,generate excessively re-dundant routing traffic that may lead to broadcast storm problem (BSP ) and deteriorate the performance of MANET significantly.A probabilistic broadcasting RREQ based AODV improved routing protocol was proposed,which was marked as P_RREQ+AODV.The probability of rebroadcasting RREQ packets on the fly was determined according to the current SINR (signal to interference plus noise ratio)and node density in the neighborhood.The simulation results show that the proposed routing protocol reduces the routing overhead and improves throughput.Compared with AODV,the routing overhead of P _RREQ+AODV is reduced by 50%,and throughput is improved by 23%.%典型的按需路由协议AODV(Ad Hoc on-demand distance vector)易产生大量冗余包,可能导致广播风暴问题,降低MANET(mobile Ad Hoc networks)路由协议性能.为此,提出基于概率广播路由请求RREQ(route REQuest)控制包的AODV的改进协议,记为P_RREQ+AODV.依据信干扰比SINR(signal to interference plus noise ratio)和节点密度计算节点转发RREQ的概率,降低路由开销和传输时延,提高吞吐量.仿真结果表明,与传统的AODV协议相比,P_RREQ+AODV协议的路由开销降低了近50%,吞吐量提高了23%.

摘要:
According to the different routing trigger modes, Ad Hoc network routing protocols could fall into three categories including proactive, on-demand and hybrid routing protocols. This paper mainly discusses and analyzes hybrid ZRP routing protocol. Simulation with NS-2 is done on packet delivery ratio , routing overhead and end-to-end delay of hybrid ZRP routing protocol, and comparison of this protocol with typical routing protocol DSDV and AODV in Ad hoc network made. Experiment and analysis indicate that ZRP, combined with the advantages of AODV and DSDV protocols in Ad hoc network, could improve packet delivery ratio while effectively control the routing overhead, and meanwhile, the end-to-end delay is also reduced to some extent. This is of great significance to the research of Ad hoc routing protocols.%根据路由的触发方式不同,移动Ad Hoc网络路由协议可分为先验式、按需式和混合式路由协议三类。主要对混合式路由协议ZRP进行研究,通过网络仿真工具NS2对该协议的分组投递率、路由开销及端对端时延进行仿真,并与Ad hoc网络典型路由协议DSDV和AODV的仿真结果进行比较。分析结果表明, ZRP 路由协议结合了Ad hoc网络AODV和DSDV协议的优点,在提高分组投递率的同时,路由开销得到了有效的控制,并且在一定程度上缩短了端对端时延,对Ad hoc 路由协议的研究具有重要的意义。
