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...
In this paper, we present a trust establishment and management framework for hierarchical wireless sensor networks. The wireless sensor network architecture we consider consists of a collection of sensor nodes, cluster heads and a base station arranged hierarchically. The framework encompasses schemes for establishing and managing trust between these different entities. We demonstrate that the proposed...
Ad-hoc networks establish communication in improvised environments without requiring any fixed infrastructure. These networks are inherently prone to security attacks, with node mobility being the primary cause in allowing security breaches. Therefore secure routing is a must for such networks. A number of secure routing protocols based on trust have recently been proposed. However, all these protocols...
The absence of a router or a base station urges the need for a better access control mechanism in the ad-hoc networks. All the nodes in the network need to cooperate among themselves for proper functioning of the network. It is important to provide access only to the nodes, which cooperate in routing and forwarding, and to deny access to the selfish nodes. Selfish nodes send and receive their own...
