    摘要:

    隨著(zhù)“網(wǎng)絡(luò )中心戰”、“網(wǎng)電一體戰”概念的提出,自組網(wǎng)在組網(wǎng)通信中扮演著(zhù)越來(lái)越重要的角色。在實(shí)際應用中,自組網(wǎng)常常面臨著(zhù)電磁頻譜環(huán)境復雜,無(wú)線(xiàn)設備偵聽(tīng)干擾頻繁等問(wèn)題,對網(wǎng)絡(luò )的抗干擾、抗截獲性能提出了更高的要求。針對上述問(wèn)題,提出一種多路由冗余傳輸算法,源節點(diǎn)對原始數據進(jìn)行冗余編碼,利用多徑路由協(xié)議發(fā)現多條路由并行傳輸編碼包,目的節點(diǎn)只需接收到一定數量的編碼包即可恢復出全部原始信息。該算法有效融合了多徑路由和冗余編碼的特點(diǎn),具有抗干擾、抗截獲和無(wú)需重傳的優(yōu)勢。利用OPNET Modeler仿真平臺進(jìn)行仿真建模,測試了多路由冗余傳輸算法下通信節點(diǎn)對之間收發(fā)包數量以及監聽(tīng)節點(diǎn)截獲數據包情況。試驗表明,多路由冗余傳輸算法能有效提高網(wǎng)絡(luò )的抗干擾、抗截獲性能。

    Abstract:

    With the proposing of “Network Center Warfare” and “Integrated Electricity Network Warfare”, MANET plays an important role in network communication. The practical application environment of MANET is usually filled with complex electromagnetic spectrum, frequent hostile monitor and hostile interference, which resulting in higher requirements about the performance of anti-jamming and anti-interception. According to the above questions, the multipath redundant transmission algorithm is proposed: source node redundant codes the original data into coding packets, parallelly transports the coding packets by the paths calculated by the multipath routing protocol, and destination node can recover the original data by receiving a certain number of coding packets. Combining the multipath routing protocol with redundant coding, the algorithm proposed has the advantage of anti-jamming, anti-interference and without retransmission. Based on OPNET Modeler platform, the number of the packets between the communication nodes under the scenario of lost packet caused by interference and the packets intercepted by monitor node is tested. The test shows that the multipath redundant transmission algorithm can effectively improve the network performance of anti-jamming and anti-interception.
