Innovative ways to use ad hoc networking between vehicles are an active research topic and numerous proposals have been made for applications that make use of it. Due to the bandwidth-limited wireless communication medium, scalability is one crucial factor for the success of these future protocols. Data aggregation is one solution to accomplish such scalability. The goal of aggregation is to semantically...
The weakest defect among the security modes which IEEE 802.15.3 WPAN (wireless personal area networks) provides is the assumption that secret membership is pre-distributed in advance to the communicating nodes by a central key distributor. However, this assumption is inappropriate in WPAN ad hoc environment, since the wireless ad hoc network has no the central administrator node, moreover, the network...
As ad hoc network has advanced, the importance of security increases more and more. But it suffers from the restriction that ad hoc network does not have the established infrastructure. In this paper we propose a security-enhanced model with ID-based cryptosystem, which removes the necessity for any infrastructure and provides sound authentication and a more secure and concrete routing protocol with...
Mobile ad hoc networks are infrastructure-free, pervasive, ubiquitous and without any centralized authority. These unique characteristics, combined with security threats, demand solutions for securing ad hoc networks prior to their deployment in commercial and military applications. So far, the research in mobile ad hoc network has been primarily focused on routing and mobility aspects rather than...
