Video Transport Improvement over MANET

Real-time multimedia transport over MANET has stringent bandwidth, delay, and loss requirements. It is a great challenge to support such applications in wireless ad hoc networks, which are characterized by frequent link failures, congestion, and lack of central administration.

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.

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.
