Metric-Based Cooperative Routing in Multihop Ad Hoc Networks

Collaborative Trust-Based Secure Routing in Multihop Ad Hoc Networks

In this paper we have proposed a secure routing protocol based on AODV for multihop ad hoc networks. Our protocol is unique in the sense that it is capable of finding a secure end-to-end route free of any malicious entity, thus resisting an internal attack within the network either in the form of compromised or disloyal nodes. We propose to find a secure and efficient route to a destination bas...

Topological Cluster-based Geographic Routing in Multihop Ad Hoc Networks

Existing geographic routing algorithms face serious challenges due to location errors, nonplanarity issues and overhead of location service. To solve these issues, we propose Topological Cluster Based Geographic Routing that combines topology-based routing and geographic routing. It is a localized routing scheme where the geographic routing is performed on an overlay network of topological clus...

Virtual Backbone-Based Routing in Multihop Ad Hoc Wireless Networks

Recent research ([12][15][19]) shows that the flooding mechanism (for topology update or route request) used in existing protocols for ad hoc wireless networks greatly degrades the network capacity. If we force the effective broadcasts of control packets happen in a small subset of hosts in the network, the protocol overhead caused by global flooding can be substantially reduced. This is the ba...

Shadowing Effects on Routing Protocol of Multihop Ad Hoc Networks

Two-ray ground reflection model has been widely used as the propagation model to investigate the performance of an ad hoc network. But two-ray model is too simple to represent a real world network. A more realistic model namely shadowing propagation model has been used in this investigation. Under shadowing propagation model, a mobile node may receive a packet at a signal level that is below a ...
