There has been much research focusing on the routing problem in delay tolerant networks (DTNs). Much of the work has mainly focused on coding schemes for message distribution, while other work has been done on the probabilistic forwarding. Coding schemes achieve higher delivery rate via redundancy before forwarding, while probabilistic forwarding efficiently limits the abuse of the store and forward...
Over the past years, location-based routing protocols have been studied extensively in mobile ad hoc networks (MANETs). However, how to efficiently provide the location information for nodes is still a challenge. So far, many protocols have been proposed to solve this problem, most of which offer exact routing location information, and are complicated to implement in practice. In this paper, we propose...
Data privacy in vehicular ad hoc networks (VANETs) is a practical issue currently under investigation. Privacy-preserving anonymity authentication in networks is a challenging topic related to security, anonymity, network, and data privacy. Existing anonymity authentication in VANET is based on a k-anonymity model. An on board unit (OBU) chooses an adaptive anonymity group size in a request to an...
The publish/subscribe (pub/sub for short) paradigm is used to deliver events from a source to interested clients in an asynchronous way. Recently, extending a pub/sub system in wireless networks has become a promising topic. However, most existing works focus on pub/sub systems in infrastructured wireless networks. To adapt pub/sub systems to mobile ad hoc networks, we propose DRIP, a dynamic Voronoi...
In localized topology control protocols for mobile ad hoc networks (MANETs), each node selects a few logical neighbors from its 1-hop neighbors based on its local view, constructed by exchanging periodical "Hello" messages among neighbors, and uses a small transmission range to cover those logical neighbors. Transmission range reduction conserves energy and bandwidth consumption, while still...
