Routing in MANET is complex due to the fact that the network graph is episodically connected and nodes get only intermittently connected because of nodes mobility, terrain, weather, and jamming that change topology rapidly. In this paper, we propose cross-layer design to achieve a reliable data transmission in MANET. A key challenge is to create a mechanism that can provide good delivery perfor...

Many routing protocols for ad hoc networks have been proposed to date. Among them, STAR is a representative table-driven protocol, while AODV and DSR are two representative on-demand protocols. This paper analyzes these three protocols using the GloMoSim simulation environment. The scenarios used in the simulation experiments take into account a variety of environmental factors that influence p...

Ad hoc routing technology has been developed primarily for networks of mobile nodes. In many cases the operational life of a node will be limited by its power source, so power consumption can be a critical issue. All the layers of communication are coupled in power consumption. Ad hoc routing protocols may consume different amounts of power and their routing decisions may be conditioned. Power ...

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Due to the dynamic nature of the network topology congestion and load balancing are the major problem in Mobile Ad-hoc Networks routing. Most of the existing protocols provide solutions to load balancing or congestion or fault tolerance individually. In...

Vehicular Ad hoc Network is one of the interesting and attractive topics in the recent years. It has a potential to achieve intelligent inter vehicle communication for the benefit of the vehicle user. The VANET has lot of challenges. These decentralized dynamic networks require a secure communication. These networks are vulnerable to various attacks. In this paper the security features of routi...

Performance on multi-hop networks suffers from limited channel capacity and poor scalability problem as the network size or density increases(Gupta and Kumar, 2000). One way to alleviate this problem is to equip each node with multiple radios. As hardware cost drops, this approach becomes more and more appealing and feasible. By tuning radios into non-interfering channels, the wireless spectrum...

In this paper we evaluate the performance of the Stream Control Transmission Protocol (SCTP) in a wireless ad-hoc network environment under two routing protocols: DSR and AODV. Furthermore, we propose a cross-layer optimization to the SCTP and DSR protocols, that handles pro-actively route failures. The novelty in the proposed mechanism consists in the identification of route failures which is ...

Ad-hoc wireless networks are defined as the category of wireless networks that utilize multi hope radio relaying and are capable of operating without the support of any fixed infrastructure. Wireless mesh networks and wireless sensor networks are specific examples of wireless ad-hoc networks. This paper discusses in detail the functioning of AODV and DSR routing protocol In different propagatio...

Energy consumption is a key issue in mobile ad hoc networks.To reduce the energy consumption of the network interface, it is necessary to turn it off, immediately affecting the routing protocols. Therefore, routing protocols and energy saving algorithms must be designed to work within each other. This article presents the use of energy management, using the load balance technique with single pa...

In our previous work we created a new ad hoc routing protocol MYLAR1, by modifying LAR1 routing protocol. The previous work showed that MYLAR1 routing protocol showed better performance as compared to LAR1 routing protocol in performance parameters such as: end to end delay, throughput, jitter and packets received without error. This paper discusses the comparison of MYLAR1 with other ad hoc ro...
