We propose and present a framework for enabling policy-based routing in mobile ad hoc networks (MANETs) by applying policy rules associated with the security and reliability (of connection) to peer-to-peer security associations (SA) that are established on (multi-link) routes. In this proposal, we leverage and integrate the concept of dispersity routing with the management and maintenance of an existing...
Mobile Ad Hoc Network (MANET) has become significantly important to support self-organizing roaming computing with changing links to neighboring hosts. The topology is changed so rapidly, finding a routing path is a challenge in reactive protocol methodology. Securing ad hoc networks is infamously challenging, notably due to the lack of an online infrastructure. MANET poses a number of security challenges...
A mobile ad hoc network (MANET) is a collection of mobile nodes that communicate with each other by forming a multi-hop radio network. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, and lack of clear lines of defense. Design of an efficient and...
The specific characteristics of Mobile Ad Hoc Networks (MANETs) make secure transmission important issues in its research. In this paper, we present a scheme using soft encryption combined with multipath routing to provide security of data transmission over MANETs. In the scheme, the messages are divided into different parts and encrypted by simple operations such as XOR function and bits rearrangement...
The peer-to-peer network has been widely used to share large files anonymously. Because of its open nature, nodes can join and leave peer-to-peer networks freely. But there are few limited methods to ensure their trust. Malicious nodes can expose great security threats to peer-to-peer networks such as spreading unauthentic data and viruses. But handling all the malicious nodes in the same way causes...
