摘要: 間斷連接無線網絡中的節(jié)點以協(xié)作方式完成消息投遞，惡意節(jié)點將嚴重影響網絡性能。利用節(jié)點歷史行為信息，該文提出一種惡意節(jié)點容忍的消息轉發(fā)策略，節(jié)點結合直接觀察信息與鄰居節(jié)點的推薦信息，通過動態(tài)推薦聲譽閾值感知節(jié)點惡意行為，進而利用證據理論量化節(jié)點信任度，從而檢測網絡中串謀及獨立的惡意節(jié)點，為消息選擇最優(yōu)的轉發(fā)節(jié)點。結果表明，在帶有串謀的惡意攻擊下，所提出的消息轉發(fā)策略能準確檢測出惡意節(jié)點，并顯著提高消息投遞率，改善平均時延。Abstract: Packets in ICWN (Intermittently Connected Wireless Network) are delivered in a cooperation manner between nodes, which means the existence of malicious nodes will degrade the network performance. A malicious node tolerant message forwarding mechanism is proposed in this paper. By exploiting the historical node behavior information, directly observed information is combined with the recommendation information from neighbor nodes to perceive malicious node behavior according to the dynamical reputation threshold. Consequently, evidence theory is utilized to quantify the node relation to detect malicious nodes, and then the optimal relay nodes selecting can be achieved. Results show that, under the attack of collaborating malicious nodes, malicious nodes can be accurately identified by the proposed mechanism, which leads to the notably improving packet delivery ratio and average delay.
