Security is an important issue in mobile ad hoc networks (MANETs). However, security schemes have significant impacts on throughput. That is because 1) they need some overhead and consume some network resources, thus decrease throughput consequently, 2) most previous works consider security and throughput separately in designing a MANET, which can not achieve an overall optimization of network performance...
Mobile multi-hop relay (MMR) WiMAX networks have attracted lots of interest in the wireless communication industry recently because of its scalable coverage, improved data rates and relatively low cost. However, security of MMR WiMAX networks is the main challenge. In this paper, we first identify a possible attack on MMR WiMAX networks in which a rogue base station (BS) or relay station (RS) can...
Vehicular ad hoc networks have attracted a lot of attention in recent years, in either vehicle-to-vehicle or vehicle-to-infrastructure scenarios. In this paper, we focus on the latter, particularly for vehicles to upload to roadside units, the so-called drive-thru Internet, in a secure and efficient manner. Due to the ad hoc nature and wireless communications, traditional certificate-based security...
