Evaluating performance and reliability of AODV, ADV routing protocols in VANET environment using NCTUns 6.0 simulator

In this paper, we use NCTUns 6.0 to simulate this kind of networks ,because it is difficult to do that is the real world .In this paper, two routing protocols (AODV, ADV) are studied within many scenarios to achieve their performances and reliability using many metrics. We conclude that ADV routing protocol adapts quickly when the complexity of network and mobility of nodes increase. This is achieved by varying the size and frequency of routing updates.

Performance evaluation of AODV and hierarchical routing Protocol in wireless sensor network based on IEEE802.15.4 Standard

Routing protocols play an essential role in meeting the quality of service requirements in the network, but achieving these requirements may require frequent send and receive operations to build and maintain routing tables, which consume sensors resource If we take into consideration the limitations of wireless sensor networks in terms of the amount of available energy and storage capacity. In this research a performance comparison of the on-demand Distance Vector Routing protocol AODV and Hierarchical Routing protocolHR was carried out in terms of the packet delivery and loose rate, delay and jitter, and the amount of expended energy in the Wireless sensor network operates according to IEEE802.15.4 standard in cases where some of sensors get out of work for limited periods of time. The results showed that the hierarchical routing protocols perform better in terms of delay time and transfer rate and the amount of consumed energy than on-demand Distance Vector Routing protocol routing protocol, but suffer larger packet loss due to routing path corruption as a result of sensors crashes.

Integrating security keys exchange in the secure routing in AODV protocol

Mobile ad-hoc Networking MANETS is a promising concept to provide flexible, adaptive, and reconfigurable architecture, cost effective solution.In the mobile ad hoc network security is the basic concern for network functions work properly.Routing is the corner stone in Mobile ad-hoc Networks, A lot of known vulnerabilities and security threats can be exploited to attack routing messages, so it is important to provide secure routing protocol for MANETs.In this paper, we present a secure extension for ad-hoc On Demand Distance Vector Protocol (AODV). The default routing protocol for MANETs. The proposed protocol ensures that discovery of the route between the nodes is functioning properly and securely, achieving mutual authentication between nodes, routing message integrity, generating a security key of data sent and exchanges it securely to ensure confidentiality and all of these are in one stage. By this we save in wireless band, resource consumption, preventing duplicate of authentication algorithms.
