Whenever streaming of multimedia based data such as video, audio and text is performed traffic will be more and network becomes congested in mobile ad hoc networks. The present routing protocols are not able to cope up with this situation. It is observed that network congestion is the dominant reason for packet loss, longer delay and delay jitter in streaming video. Most of the present routing ...

Proactive MANET routing protocols tend to provide smaller route discovery latency than ondemand protocols because they maintain route information to all the nodes in the network at all time. However, the downside for such protocols is the excessive routing control overhead that is generated by disseminating periodic HELLO messages and topology control messages. Due to the resource-constrained n...

Routing packets in mobile ad hoc networks has been considered to a great extent, even though the hypothesis on full connectivity is generally not valid in a real time system which means that a practical routing protocol ought to handle intermittent connectivity and the absence of end-to-end connections. In this paper, we propose a location aware routing mechanism called adaptive position based ...

In Manet’s Dynamics and Robustness are the key features of the nodes and are governed by several routing protocols such as AODV, DSR and so on. However in the network the growing resource demand leads to resource scarcity. The Node Mobility often leads to the link breakages and high routing overhead decreasing the stability and reliability of the network connectivity. In this context, the paper...

This article presents analysis of the design and simulation of a new class of environmentally aware clustering algorithms for wireless ad hoc networks. The clustering algorithm establishes an adap-tive self-organizing arrangement that enables multimode routing strategies. Multimode operation is needed to enhance scalability and robustness. In the present case, clustering is based on a criterion...

We propose and analyze a class of integrated social and quality of service (QoS) trust-based routing protocols in mobile ad-hoc delay tolerant networks. The underlying idea is to incorporate trust evaluation in the routing protocol, considering not only QoS trust properties but also social trust properties to evaluate other nodes encountered. We prove that our protocol is resilient against bad-...

This paper compares Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Wireless Routing Protocol (WRP) for MANETs to Distance Vector protocol to better understand the major characteristics of the three routing protocols, using a parallel discrete event-driven simulator, GloMoSim. MANET (mobile ad hoc network) is a multi-hop wireless network without a fixed infrastructure...

Vehicular Ad-Hoc Networks can enhance road safety and enable drivers to avoid different threats. Safety applications, mobile commerce, and other information services are among different available services that are affected by dynamic topology, vehicle’s speed and node misbehaving. Dynamic topology makes the route unstable and unreliable. So, improving the throughput and performance of VANET thr...

Increasing popularity and availability of portable wireless devices, which constitute mobile ad hoc networks, calls for scalable ad hoc routing protocols. On-demand routing protocols adapt well with dynamic topologies of ad hoc networks, because of their lower control overhead and quick response to route breaks. But, as the size of the network increases, these protocols cease to perform due to ...

We introduce WRP-Lite, which is a table-driven routing protocol that uses non-optimal routes, and compare its performance with the performance of the dynamic source routing (DSR) protocol, which is an on-demand routing protocol for wireless ad-hoc networks. We evaluate the performance of WRP-Lite and DSR for varying degree of mobility and traffic in a 20-node network. The performance parameters...
