The latest technology MANETs is being studied widely and attracting a large variety of applications. Due to varying network topology, The most common challenging factor in MANET is routing [2][3]. In this research paper, we study the performance of reactive routing protocols, Ad hoc on demand Distance Vector (AODV) and Dynamic Source Routing (DSR) and proactive routing protocol Destination Sequ...

An ad-hoc network is a spontaneous network that emerges when two or more wireless nodes pledge to help each other. As the wireless range of these nodes is usually limited so each node commits to forward the packets on behalf of its neighbours in accordance with a predefined routing protocol. Dynamic Source Routing (DSR) is one of the widely used routing protocols that is currently undergoing ex...

This paper presents a new Ad hoc Dynamic Source Routing (DSR) protocol based on mobility prediction, named as MDSR. The algorithm controls route discovery, route keeping and route switching according to the distance and mobility estimation of the neighbor nodes. We have implemented this protocol using a modified NS2 and studied its performance. Simulation results show that MDSR reduces the end-...

Mobile Adhoc networks are infra structure-less and are categorized by multi-hop wireless connectivity and dynamic changing network topology. They are self organized networks without dependency on any fixed infrastructure. Application area of MANET is varied, ranging from small, static networks to large scale highly mobile and highly dynamic networks. Routing is an important issue in wireless ad...

Mobile ad hoc networks (MANETS) are self-created and self organized by a collection of mobile nodes, interconnected by multi-hop wireless paths in a strictly peer to peer fashion. DSR (Dynamic Source Routing) is an on-demand routing protocol for wireless ad hoc networks that floods route requests when the route is needed. Route caches in intermediate mobile node on DSR are used to reduce floodi...

Route caching strategy is important in on-demand routing protocols in wireless ad hoc networks. While high routing overhead usually has a significant performance impact in low bandwidth wireless networks, a good route caching strategy can reduce routing overheads by making use of the available route information more efficiently. In this paper, we first study the effects of two cache schemes, “l...

Routing is continuous challenging issue in Vehicular Ad Hoc Networks (VANETs) given the intrinsic characteristics of these networks, especially limited resources and high mobility. Indeed, for any routing protocol to achieve acceptable network throughput performance it should adapt its operation to VANET high frequency topology change dynamics. In this paper an enhancement of such routing proto...

This Mobile Ad Hoc Networks (MANET) is gaining importance because of their flexibility, mobility and ability to work with a limited infrastructure. In multi-hop wireless network, proper utilization of battery power is very much necessary to maintain network connectivity.In order to overcome the network from inefficient routing problem, this paper presents different energy efficient routing prot...

Wireless ad-hoc networks are characterized by the lack of infrastructure, use of wireless links with limited bandwidth and frequent topological changes. On-demand multipath routing in wireless ad-hoc networks is effective in providing resilience to route failures and to successful load balancing. Previous work shows that on-demand multipath routing protocols achieve lower end-to-end delay, rout...
