Ad hoc wireless networks depend on mutual collaboration among nodes. Congestion in ad hoc wireless networks thus presents more of a challenge than for other network types. This article proposes RAODV (relieving AODV), a modification of the AODV routing protocol, to handle congestion via third party neighbour nodes in dense and static ad hoc networks. RAODV nodes use a T-entropy threshold-based congestion detection algorithm to determine the congestion status of their neighbours. If RAODV determines that congestion is occurring, it then tries to relieve congestion via a local repair modification algorithm that replaces the congested node by a suitable monitoring/third party neighbour node. This article also shows evidence that RAODV results in better network performance than AODV in simulations with random network topologies.

We introduce AIR, a new ant-based routing protocol for ad hoc wireless networks. AIR incorporates recent technology advances in ad hoc routing protocols, such as ring-based searching and third-party reply, while retaining the characteristics and benefits of ant-based routing protocols, including probabilistic routing tables and pheromone evaporation. In addition, we combine the best features of previous ant-based routing protocols with new features like update ants and two-way route establishment, to further improve performance. We compare the performance of AIR against AODV and DSR using appropriately chosen simulations, the results of which are presented and discussed. We find that AIR is especially useful for ad hoc networks requiring low end-to-end delay where mobility rates are high.

Aodv Routing Protocol

Vehicular ad hoc networks is an emerging area for researchers to provide intelligent transportation system to the society. It is due to the wide area of applications of VANETs interest is developed among the people from different countries to be a part of it. Therefore many projects had been started and also presently working to implement VANETs in real world scenario. The main challenge in its implementation is to provide a secure mechanism against the various attacks and threats that have the capability to bring the network performance significantly down. In this paper to overcome different types of authentication based attacks in VANETs an ECDSA based secure routing protocol SE-AODV is proposed with security features incorporated in already existing AODV routing protocol. The performance of SE-AODV is evaluated and compared with original AODV and AODV with black hole attack (BH-AODV). The SE-AODV shows better performance with the parameters used for comparison with the variation in vehicle density, speed of vehicles and simulation time.

Ad-hoc networks consist of a set of mobile nodes with a restricted power supply resources that can communicate with each other without any established infrastructure or centralized administration. The loss of some nodes may cause significant topological changes, undermine the network operation, and affect the lifetime of the network. This paper discusses the energy consumption problem and summaries the existing power saving techniques in ad-hoc wireless networks. The main objective of this paper is to introduce a new power aware multi-path node disjoint routing scheme based on the Dynamic Source Routing protocol (DSR), which can prolong MANETs lifetime, reduce routing delay and increase the reliability of the packets reaching its destination. Therefore, a comprehensive study of DSR protocol has been drawn using NS-2 simulator, to evaluate the performance of DSR as a routing strategy and investigate its efficiency in saving wireless networks resources, as a prelude to avoid its performance shortcomings in our proposed routing scheme. Keywords: Power aware protocol, node disjoint, network simulation 2, multipath routing, Dsr protocol, ad-hoc network.
