In this thesis, we consider a multi-channel ad hoc network employing frequencyagile radios that utilize direct-sequence spread-spectrum signaling. Two of the key distributed protocols for this type of network control channel access and routing. The channel-access protocol is responsible for controlling access to the channels available to the terminals in the network, and the routing protocol determines how packets are forwarded among the terminals in the network. To achieve reliable and efficient network performance, these protocols should cooperate with one another and take advantage of the multiple channels available to the network.In this thesis, we investigate a number of channel-access strategies for selecting a channel as well as various channel metrics to be used with routing. For our channelaccess protocol, one channel is designated the control channel and is used to reserve access to one of the traffic channels. The channel-access protocol selects the traffic channel for a data packet transmission by examining the characteristics of the different traffic channels. New channel metrics are proposed to characterize the channels, and the metric values are used to assign a link resistance value for a link. Least-resistance routing utilizes the link resistances to calculate routes. The performance of the channel metrics for the routing protocol and the channel-access strategies are examined with a discreteevent simulation. From our investigations, we show that a jointly designed protocol that coordinates the channel-access strategies with the channel metrics results in network performance that is better than traditional channel-access and minimum-hop routing protocols.iii ACKNOWLEDGMENTS

“…What is more, taking the high speed of the vehicles into consideration, the time cost for the handover in different clusters has to be lowered down. So, figuring out a new robust system to provide the high speed service under the VANETs is in high demand [3,7,15,18,21]. Aside from that, seeing to the self-organizing, decentralized topology, and high speed movement characteristics, how to provide an efficient and secure communication mechanism for VANETs is of great challenge although many open security issues are still unsolved.…”

Vehicle ad hoc networks are self-configurable networks with dynamic topologies. All involved nodes in vehicle ad hoc networks, including vehicles and roadside devices, have to share the responsibility for achieving handover operation and providing communication services. Such networks are more vulnerable to the malicious attacks than traditional wireless networks because of the shortage of the fixed infrastructure. Moreover, because the vehicles always move from one area to another very quick, how to handle the handover between roadside devices has become a crucial challenge in designing the system. For providing secure and seamless communications in such networks, we develop a robust and fast handover mechanism. We have conducted essential experiments to demonstrate the superiority of the new mechanism to other works. In particular, we have applied the BAN logic model to prove the correctness of mutual authentication between involved participants.

SummarySince the early 1990s, engineers have proposed many mechanisms for providing confidential communications and data integrity in mobile ad hoc networks (MANET). The deficiency of fastened infrastructure makes mobile ad hoc networks more vulnerable to security threats than conventional wireless networks. MANET can be considered as a short-lived collection of mobile nodes that communicate with each other in between. All involved nodes in the network system share the responsibility for routing, accessing, and communicating. The main challenges on the design of MANET include high power saving and low bandwidth. The public key infrastructure (PKI) is a wellknown mechanism used to provide data integrity and confidential communications in MANET recently. The computation loads of PKI, however, are heavy to each mobile node in the cluster. Without adopting PKI cryptosystems to en/decrypt messages, we propose a novel version based on a variant Diffie-Hellman protocol. The novel method can preserve the forward and backward secrecy of group communications. Specifically, the new method outperforms related works in the computation overheads of involved nodes while communicating with other nodes.
