Mobile ad hoc networks (MANETs) are infrastructureless. As such, they are subject to various types of security attacks if malicious nodes are present in the network. One of such attacks is the wormhole attack. In an earlier work, a scheme (called Cell-based Open Tunnel Avoidance (COTA)) was proposed to address this problem, which consisted in a mechanism for detecting and classifying the wormhole...
In mobile ad hoc networks (MANETs), nodes are mobile and have limited energy resource that can quickly deplete due to multi-hop routing activities, which may gradually lead to an un-operational network. In the past decade, the hunt for a reliable and energy-efficient MANET srouting protocol has been extensively researched. This paper proposes a novel Ant Net-based routing scheme for MANETs (so-called...
This paper continues the investigation of our recently proposed protocol (called E2-SCAN) designed for protecting against network layer attacks in mobile ad hoc networks. The enhancements of the E2-SCAN protocol are twofold: (1) a modified credit strategy for tokens renewal is introduced, and (2) a novel strategy for selecting the routing path, resulting to our so-called Conditional SCAN (CSCAN)....
